org.freedesktop.systemd1 — The D-Bus interface of systemd
systemd(1) and its auxiliary daemons expose a number of APIs over D-Bus. This page only describes the various APIs exposed by the system and service manager itself. It does not cover the auxiliary daemons.
The service manager exposes a number of objects on the bus: one
Manager
object as a central entry point for clients along with individual objects
for each unit and for each queued job. The unit objects each implement a generic
Unit
interface as well as a type-specific interface. For example, service units
implement both org.freedesktop.systemd1.Unit
and
org.freedesktop.system1.Service
. The manager object can list
unit and job objects or directly convert a unit name or job id into a bus path of the corresponding
D-Bus object.
Properties exposing time values are usually encoded in microseconds (usec) on the bus, even if their corresponding settings in the unit files are in seconds.
In contrast to most of the other services of the systemd suite, PID 1 does not use polkit for controlling access to privileged operations, but relies exclusively on the low-level D-Bus policy language. (This is done in order to avoid a cyclic dependency between polkit and systemd/PID 1.) This means that sensitive operations exposed by PID 1 on the bus are generally not available to unprivileged processes directly. However, some operations (such as shutdown/reboot/suspend) are made available through the D-Bus API of logind, see org.freedesktop.login1(5).
The main entry point object is available on the fixed
/org/freedesktop/systemd1
object path:

Note that many of the methods exist twice: once on the Manager
object and once on the respective unit objects. This is to optimize access times so that methods that
belong to unit objects do not have to be called with a resolved unit path, but can be called with only
the unit id, too.
GetUnit()
may be used to get the unit object path for a unit name. It takes
the unit name and returns the object path. If a unit has not been loaded yet by this name this method
will fail.
GetUnitByPID()
may be used to get the unit object path of the unit a process
ID belongs to. It takes a UNIX PID and returns the object path. The PID must refer to an existing system process.
LoadUnit()
is similar to GetUnit()
but will load the
unit from disk if possible.
StartUnit()
enqueues a start job and possibly depending jobs. It takes the unit
to activate and a mode string as arguments. The mode needs to be one of "replace
",
"fail
", "isolate
", "ignore-dependencies
", or
"ignore-requirements
". If "replace
", the method will start the unit and
its dependencies, possibly replacing already queued jobs that conflict with it. If
"fail
", the method will start the unit and its dependencies, but will fail if this would
change an already queued job. If "isolate
", the method will start the unit in question
and terminate all units that aren't dependencies of it. If "ignore-dependencies
", it
will start a unit but ignore all its dependencies. If "ignore-requirements
", it will
start a unit but only ignore the requirement dependencies. It is not recommended to make use of the
latter two options. On completion, this method returns the newly created job object.
StartUnitReplace()
is similar to StartUnit()
but
replaces a job that is queued for one unit by a job for another unit.
StopUnit()
is similar to StartUnit()
but stops the
specified unit rather than starting it. Note that the "isolate
" mode is invalid for this
method.
ReloadUnit()
, RestartUnit()
,
TryRestartUnit()
, ReloadOrRestartUnit()
, or
ReloadOrTryRestartUnit()
may be used to restart and/or reload a unit. These methods take
similar arguments as StartUnit()
. Reloading is done only if the unit is already
running and fails otherwise. If a service is restarted that isn't running, it will be started unless
the "Try" flavor is used in which case a service that isn't running is not affected by the restart. The
"ReloadOrRestart" flavors attempt a reload if the unit supports it and use a restart otherwise.
KillUnit()
may be used to kill (i.e. send a signal to) all processes of a
unit. It takes the unit name
, an enum who
and a UNIX
signal
number to send. The who
enum is one of
"main
", "control
" or "all
". If
"main
", only the main process of the unit is killed. If "control
", only
the control process of the unit is killed. If "all
", all processes are killed. A
"control
" process is for example a process that is configured via
ExecStop=
and is spawned in parallel to the main daemon process in order to shut it
down.
GetJob()
returns the job object path for a specific job, identified by its
id.
CancelJob()
cancels a specific job identified by its numeric ID. This
operation is also available in the Cancel()
method of Job objects (see below) and
exists primarily to reduce the necessary round trips to execute this operation. Note that this will not
have any effect on jobs whose execution has already begun.
ClearJobs()
flushes the job queue, removing all jobs that are still
queued. Note that this does not have any effect on jobs whose execution has already begun. It only
flushes jobs that are queued and have not yet begun execution.
ResetFailedUnit()
resets the "failed" state of a specific unit.
ResetFailed()
resets the "failed" state of all units.
ListUnits()
returns an array of all currently loaded units. Note that
units may be known by multiple names at the same name, and hence there might be more unit names loaded
than actual units behind them. The array consists of structures with the following elements:
The primary unit name as string
The human readable description string
The load state (i.e. whether the unit file has been loaded successfully)
The active state (i.e. whether the unit is currently started or not)
The sub state (a more fine-grained version of the active state that is specific to the unit type, which the active state is not)
A unit that is being followed in its state by this unit, if there is any, otherwise the empty string.
The unit object path
If there is a job queued for the job unit, the numeric job id, 0 otherwise
The job type as string
The job object path
ListJobs()
returns an array with all currently queued jobs. Returns an array
consisting of structures with the following elements:
The numeric job id
The primary unit name for this job
The job type as string
The job state as string
The job object path
The unit object path
Subscribe()
enables most bus signals to be sent out. Clients which are
interested in signals need to call this method. Signals are only sent out if at least one client
invoked this method. Unsubscribe()
reverts the signal subscription that
Subscribe()
implements. It is not necessary to invoke
Unsubscribe()
as clients are tracked. Signals are no longer sent out as soon as
all clients which previously asked for Subscribe()
either closed their connection
to the bus or invoked Unsubscribe()
.
Reload()
may be invoked to reload all unit files.
Reexecute()
may be invoked to reexecute the main manager process. It will
serialize its state, reexecute, and deserizalize the state again. This is useful for upgrades and is a
more comprehensive version of Reload()
.
Exit()
may be invoked to ask the manager to exit. This is not available for
the system manager and is useful only for user session managers.
Reboot()
, PowerOff()
, Halt()
, or
KExec()
may be used to ask for immediate reboot, powering down, halt or kexec
based reboot of the system. Note that this does not shut down any services and immediately transitions
into the reboot process. These functions are normally only called as the last step of shutdown and should
not be called directly. To shut down the machine, it is generally a better idea to invoke
Reboot()
or PowerOff()
on the
systemd-logind
manager object; see
org.freedesktop.login1(5)
for more information.
SwitchRoot()
may be used to transition to a new root directory. This is
intended to be used by initial RAM disks. The method takes two arguments: the new root directory (which
needs to be specified) and an init binary path (which may be left empty, in which case it is
automatically searched for). The state of the system manager will be serialized before the
transition. After the transition, the manager binary on the main system is invoked and replaces the old
PID 1. All state will then be deserialized.
SetEnvironment()
may be used to alter the environment block that is passed
to all spawned processes. It takes a string array of environment variable assignments. Any previously set
environment variables will be overridden.
UnsetEnvironment()
may be used to unset environment variables. It takes a
string array of environment variable names. All variables specified will be unset (if they have been
set previously) and no longer be passed to all spawned processes. This method has no effect for variables
that were previously not set, but will not fail in that case.
UnsetAndSetEnvironment()
is a combination of
UnsetEnvironment()
and SetEnvironment()
. It takes two
lists. The first list contains variables to unset, the second one contains assignments to set. If a
variable is listed in both, the variable is set after this method returns, i.e. the set list overrides the
unset list.
ListUnitFiles()
returns an array of unit names and their enablement
status. Note that ListUnit()
returns a list of units currently loaded into memory,
while ListUnitFiles()
returns a list of unit files that were
found on disk. Note that while most units are read directly from a unit file with the same name, some
units are not backed by files and some files (templates) cannot directly be loaded as units but need
to be instantiated instead.
GetUnitFileState()
returns the current enablement status of a specific unit
file.
EnableUnitFiles()
may be used to enable one or more units in the system (by
creating symlinks to them in /etc/
or /run/
). It takes a list
of unit files to enable (either just file names or full absolute paths if the unit files are residing
outside the usual unit search paths) and two booleans: the first controls whether the unit shall be
enabled for runtime only (true, /run/
), or persistently (false,
/etc/
). The second one controls whether symlinks pointing to other units shall be
replaced if necessary. This method returns one boolean and an array of the changes made. The boolean
signals whether the unit files contained any enablement information (i.e. an [Install]) section. The
changes array consists of structures with three strings: the type of the change (one of
"symlink
" or "unlink
"), the file name of the symlink and the
destination of the symlink. Note that most of the following calls return a changes list in the same
format.
Similarly, DisableUnitFiles()
disables one or more units in the system,
i.e. removes all symlinks to them in /etc/
and /run/
.
The EnableUnitFilesWithFlags()
and DisableUnitFilesWithFlags()
take in options as flags instead of booleans to allow for extendability, defined as follows:
#define SD_SYSTEMD_UNIT_RUNTIME (UINT64_C(1) << 0) #define SD_SYSTEMD_UNIT_FORCE (UINT64_C(1) << 1) #define SD_SYSTEMD_UNIT_PORTABLE (UINT64_C(1) << 2)
SD_SYSTEMD_UNIT_RUNTIME
will enable or disable the unit for runtime only,
SD_SYSTEMD_UNIT_FORCE
controls whether symlinks pointing to other units shall be
replaced if necessary. SD_SYSTEMD_UNIT_PORTABLE
will add or remove the symlinks in
/etc/systemd/system.attached
and /run/systemd/system.attached
.
Similarly, ReenableUnitFiles()
applies the changes to one or more units that
would result from disabling and enabling the unit quickly one after the other in an atomic
fashion. This is useful to apply updated [Install] information contained in unit files.
Similarly, LinkUnitFiles()
links unit files (that are located outside of the
usual unit search paths) into the unit search path.
Similarly, PresetUnitFiles()
enables/disables one or more unit files
according to the preset policy. See
systemd.preset(7) for more
information.
Similarly, MaskUnitFiles()
masks unit files and
UnmaskUnitFiles()
unmasks them again.
SetDefaultTarget()
changes the default.target
link. See
bootup(7) for more
information.
GetDefaultTarget()
retrieves the name of the unit to which
default.target
is aliased.
SetUnitProperties()
may be used to modify certain unit properties at
runtime. Not all properties may be changed at runtime, but many resource management settings (primarily
those listed in
systemd.resource-control(5))
may. The changes are applied instantly and stored on disk for future boots, unless
runtime
is true, in which case the settings only apply until the next
reboot. name
is the name of the unit to modify. properties
are
the settings to set, encoded as an array of property name and value pairs. Note that this is not a
dictionary! Also note that when setting array properties with this method usually results in appending to
the pre-configured array. To reset the configured arrays, set the property to an empty array first and
then append to it.
StartTransientUnit()
may be used to create and start a transient unit which
will be released as soon as it is not running or referenced anymore or the system is
rebooted. name
is the unit name including its suffix and must be
unique. mode
is the same as in StartUnit()
,
properties
contains properties of the unit, specified like in
SetUnitProperties()
. aux
is currently unused and should be
passed as an empty array. See the
New Control Group
Interface for more information how to make use of this functionality for resource control
purposes.
Note that most signals are sent out only after Subscribe()
has been invoked
by at least one client. Make sure to invoke this method when subscribing to these signals!
UnitNew()
and UnitRemoved()
are sent out each time a
new unit is loaded or unloaded. Note that this has little to do with whether a unit is available on
disk or not, and simply reflects the units that are currently loaded into memory. The signals take two
parameters: the primary unit name and the object path.
JobNew()
and JobRemoved()
are sent out each time a new
job is queued or dequeued. Both signals take the numeric job ID, the bus path and the primary unit name
for this job as arguments. JobRemoved()
also includes a result string which is one
of "done
", "canceled
", "timeout
",
"failed
", "dependency
", or
"skipped
". "done
" indicates successful execution of a
job. "canceled
" indicates that a job has been canceled (via
CancelJob()
above) before it finished execution (this doesn't necessarily mean
though that the job operation is actually cancelled too, see above). "timeout
"
indicates that the job timeout was reached. "failed
" indicates that the job
failed. "dependency
" indicates that a job this job depended on failed and the job hence
was removed as well. "skipped
" indicates that a job was skipped because
it didn't apply to the unit's current state.
StartupFinished()
is sent out when startup finishes. It carries six
microsecond timespan values, each indicating how much boot time has been spent in the firmware (if
known), in the boot loader (if known), in the kernel initialization phase, in the initrd (if known), in
userspace and in total. These values may also be calculated from the
FirmwareTimestampMonotonic
, LoaderTimestampMonotonic
,
InitRDTimestampMonotonic
, UserspaceTimestampMonotonic
, and
FinishTimestampMonotonic
properties (see below).
UnitFilesChanged()
is sent out each time the list of enabled or masked unit
files on disk have changed.
Reloading()
is sent out immediately before a daemon reload is done (with the
boolean parameter set to True) and after a daemon reload is completed (with the boolean parameter set
to False). This may be used by UIs to optimize UI updates.
Most properties simply reflect the respective options in
/etc/systemd/system.conf
and the kernel command line.
The others:
Version
encodes the version string of the running systemd instance. Note that
the version string is purely informational. It should not be parsed and one may not assume the version to
be formatted in any particular way. We take the liberty to change the versioning scheme at any time and
it is not part of the public API.
Features
encodes the features that have been enabled and disabled for this
build. Enabled options are prefixed with +, disabled options with -.
Tainted
encodes a couple of taint flags as a colon-separated list. When
systemd detects it is running on a system with certain problems, it will set an appropriate taint
flag. Taints may be used to lower the chance of bogus bug reports. The following taints are currently
known: "split-usr
", "mtab-not-symlink
",
"cgroups-missing
", "local-hwclock
". "split-usr
" is
set if /usr/
is not pre-mounted when systemd is first invoked. See
Booting Without /usr is Broken
for details why this is bad. "mtab-not-symlink
" indicates that
/etc/mtab
is not a symlink to /proc/self/mounts
as
required. "cgroups-missing
" indicates that control groups have not been enabled in the
kernel. "local-hwclock
" indicates that the local RTC is configured to be in local time
rather than UTC.
FirmwareTimestamp
, FirmwareTimestampMonotonic
,
LoaderTimestamp
, LoaderTimestampMonotonic
,
KernelTimestamp
, KernelTimestampMonotonic
,
InitRDTimestamp
, InitRDTimestampMonotonic
,
UserspaceTimestamp
, UserspaceTimestampMonotonic
,
FinishTimestamp
, and FinishTimestampMonotonic
encode
CLOCK_REALTIME
and CLOCK_MONOTONIC
microsecond timestamps
taken when the firmware first began execution, when the boot loader first began execution, when the
kernel first began execution, when the initrd first began execution, when the main systemd instance
began execution and finally, when all queued startup jobs finished execution. These values are useful
for determining boot-time performance. Note that as monotonic time begins with the kernel startup, the
KernelTimestampMonotonic
timestamp will always be 0 and
FirmwareTimestampMonotonic
and LoaderTimestampMonotonic
are to
be read as negative values. Also, not all fields are always available, depending on the used firmware,
boot loader or initrd implementation. In these cases the respective pairs of timestamps are both 0,
indicating that no data is available.
Similarly, the SecurityStartTimestamp
,
GeneratorsStartTimestamp
and LoadUnitTimestamp
(as well as their
monotonic and stop counterparts) expose performance data for uploading the security policies to the
kernel (such as the SELinux, IMA, or SMACK policies), for running the generator tools and for loading
the unit files.
NNames
encodes how many unit names are currently known. This only includes
names of units that are currently loaded and can be more than the amount of actually loaded units since
units may have more than one name.
NJobs
encodes how many jobs are currently queued.
NInstalledJobs
encodes how many jobs have ever been queued in total.
NFailedJobs
encodes how many jobs have ever failed in total.
Progress
encodes boot progress as a floating point value between 0.0 and
1.0. This value begins at 0.0 at early-boot and ends at 1.0 when boot is finished and is based on the
number of executed and queued jobs. After startup, this field is always 1.0 indicating a finished
boot.
Environment
encodes the environment block passed to all executed services. It
may be altered with bus calls such as SetEnvironment()
(see above).
UnitPath
encodes the currently active unit file search path. It is an array of
file system paths encoded as strings.
Virtualization
contains a short ID string describing the virtualization
technology the system runs in. On bare-metal hardware this is the empty string. Otherwise, it contains
an identifier such as "kvm
", "vmware
" and so on. For a full list of
IDs see
systemd-detect-virt(1).
Note that only the "innermost" virtualization technology is exported here. This detects both
full-machine virtualizations (VMs) and shared-kernel virtualization (containers).
Architecture
contains a short ID string describing the architecture the
systemd instance is running on. This follows the same vocabulary as
ConditionArchitectures=
.
ControlGroup
contains the root control group path of this system manager. Note
that the root path is encoded as the empty string here (not as "/
"!), so that it can be
appended to /sys/fs/cgroup/systemd
easily. This value will be set to the empty
string for the host instance and some other string for container instances.

implement the same operation as the respective methods on the
Manager
object (see above). However, these methods operate on the unit
object and hence do not take a unit name parameter. Invoking the methods directly on the Manager
object has the advantage of not requiring a GetUnit()
call to get the unit object
for a specific unit name. Calling the methods on the Manager object is hence a round trip
optimization.
Id
contains the primary name of the unit.
Names
contains all names of the unit, including the primary name that is also
exposed in Id
.
Following
either contains the empty string or contains the name of another
unit that this unit follows in state. This is used for some device units which reflect the unit state
machine of another unit, and which other unit this is might possibly change.

contain arrays which encode
the dependencies and their inverse dependencies (where this applies) as configured in the unit file or
determined automatically.
Description
contains the human readable description string for the
unit.
SourcePath
contains the path to a configuration file this unit is
automatically generated from in case it is not a native unit (in which case it contains the empty
string). For example, all mount units generated from /etc/fstab
have this field
set to /etc/fstab
.
Documentation
contains a string array with URLs of documentation for this
unit.
LoadState
contains a state value that reflects whether the configuration file
of this unit has been loaded. The following states are currently defined: "loaded
",
"error
", and "masked
". "loaded
" indicates that the
configuration was successfully loaded. "error
" indicates that the configuration failed
to load. The LoadError
field (see below) contains information about the cause of
this failure. "masked
" indicates that the unit is currently masked out (i.e. symlinked
to /dev/null
or empty). Note that the LoadState
is fully
orthogonal to the ActiveState
(see below) as units without valid loaded
configuration might be active (because configuration might have been reloaded at a time where a unit
was already active).
ActiveState
contains a state value that reflects whether the unit is currently
active or not. The following states are currently defined: "active
",
"reloading
", "inactive
", "failed
",
"activating
", and "deactivating
". "active
" indicates
that unit is active (obviously...). "reloading
" indicates that the unit is active and
currently reloading its configuration. "inactive
" indicates that it is inactive and
the previous run was successful or no previous run has taken place yet. "failed
"
indicates that it is inactive and the previous run was not successful (more information about the
reason for this is available on the unit type specific interfaces, for example for services in the
Result
property, see below). "activating
" indicates that the unit
has previously been inactive but is currently in the process of entering an active state. Conversely
"deactivating
" indicates that the unit is currently in the process of
deactivation.
SubState
encodes states of the same state machine that
ActiveState
covers, but knows more fine-grained states that are
unit-type-specific. Where ActiveState
only covers six high-level states,
SubState
covers possibly many more low-level unit-type-specific states that are
mapped to the six high-level states. Note that multiple low-level states might map to the same
high-level state, but not vice versa. Not all high-level states have low-level counterparts on all unit
types. At this point the low-level states are not documented here, and are more likely to be extended
later on than the common high-level states explained above.
FragmentPath
contains the unit file path this unit was read from, if there is
one (if not, it contains the empty string).
UnitFileState
encodes the install state of the unit file of
FragmentPath
. It currently knows the following states: "enabled
",
"enabled-runtime
", "linked
", "linked-runtime
",
"masked
", "masked-runtime
", "static
",
"disabled
", and "invalid
". "enabled
" indicates that a
unit file is permanently enabled. "enable-runtime
" indicates the unit file is only
temporarily enabled and will no longer be enabled after a reboot (that means, it is enabled via
/run/
symlinks, rather than /etc/
). "linked
"
indicates that a unit is linked into /etc/
permanently. "linked-runtime
"
indicates that a unit is linked into /run/
temporarily (until the next
reboot). "masked
" indicates that the unit file is masked permanently.
"masked-runtime
" indicates that it is masked in /run/
temporarily
(until the next reboot). "static
" indicates that the unit is statically enabled, i.e.
always enabled and doesn't need to be enabled explicitly. "invalid
" indicates that it
could not be determined whether the unit file is enabled.
InactiveExitTimestamp
, InactiveExitTimestampMonotonic
,
ActiveEnterTimestamp
, ActiveEnterTimestampMonotonic
,
ActiveExitTimestamp
, ActiveExitTimestampMonotonic
,
InactiveEnterTimestamp
, and InactiveEnterTimestampMonotonic
contain CLOCK_REALTIME
and CLOCK_MONOTONIC
64-bit microsecond
timestamps of the last time a unit left the inactive state, entered the active state, exited the active
state, or entered an inactive state. These are the points in time where the unit transitioned
"inactive
"/"failed
" → "activating
",
"activating
" → "active
", "active
" →
"deactivating
", and finally "deactivating
" →
"inactive
"/"failed
". The fields are 0 in case such a transition has
not yet been recorded on this boot.
CanStart
, CanStop
, and CanReload
encode
as booleans whether the unit supports the start, stop or reload operations. Even if a unit supports
such an operation, the client might not necessary have the necessary privileges to execute them.
CanIsolate
encodes as a boolean whether the unit may be started in isolation
mode.
Job
encodes the job ID and job object path of the job currently scheduled or
executed for this unit, if there is any. If no job is scheduled or executed, the job id field will be
0.
StopWhenUnneeded
, RefuseManualStart
,
RefuseManualStop
, AllowIsolate
,
DefaultDependencies
, OnFailureIsolate
,
IgnoreOnIsolate
, IgnoreOnSnapshot
map directly to the
corresponding configuration booleans in the unit file.
DefaultControlGroup
contains the main control group of this unit as a
string. This refers to a group in systemd's own "name=systemd
" hierarchy, which
systemd uses to watch and manipulate the unit and all its processes.
NeedDaemonReload
is a boolean that indicates whether the configuration file
this unit is loaded from (i.e. FragmentPath
or SourcePath
) has
changed since the configuration was read and hence whether a configuration reload is
recommended.
JobTimeoutUSec
maps directly to the corresponding configuration setting in the
unit file.
ConditionTimestamp
and ConditionTimestampMonotonic
contain
the CLOCK_REALTIME
/CLOCK_MONOTONIC
microsecond timestamps of
the last time the configured conditions of the unit have been checked or 0 if they have never been
checked. Conditions are checked when a unit is requested to start.
ConditionResult
contains the condition result of the last time the configured
conditions of this unit were checked.
Conditions
contains all configured conditions of the unit. For each condition,
five fields are given: condition type (e.g. ConditionPathExists
), whether the
condition is a trigger condition, whether the condition is reversed, the right hand side of the
condition (e.g. the path in case of ConditionPathExists
), and the status. The status
can be 0, in which case the condition hasn't been checked yet, a positive value, in which case the
condition passed, or a negative value, in which case the condition failed. Currently only 0, +1, and -1
are used, but additional values may be used in the future, retaining the meaning of
zero/positive/negative values.
LoadError
contains a pair of strings. If the unit failed to load (as encoded
in LoadState
, see above), then this will include a D-Bus error pair consisting of
the error ID and an explanatory human readable string of what happened. If it loaded successfully, this
will be a pair of empty strings.
Transient
contains a boolean that indicates whether the unit was created as a
transient unit (i.e. via CreateTransientUnit()
on the manager object).
Similarly to methods on the Manager
object, read-only access is
allowed for everyone. All operations are allowed for clients with the
CAP_SYS_ADMIN
capability or when the
org.freedesktop.systemd1.manage-units
privilege is granted by
polkit.
All service unit objects implement the
org.freedesktop.systemd1.Service
interface (described here) in addition to
the generic org.freedesktop.systemd1.Unit
interface (see above).

Most properties of the Service interface map directly to the corresponding settings in service unit files. For the sake of brevity, here's a list of all exceptions only:
TimeoutStartUSec
, TimeoutStopUSec
and
TimeoutAbortUSec
contain the start, stop and abort timeouts, in microseconds. Note
the slight difference in naming when compared to the matching unit file settings (see
systemd.service(7)):
these bus properties strictly use microseconds (and thus are suffixed …USec
) while
the unit file settings default to a time unit of seconds (and thus are suffixed
…Sec
), unless a different unit is explicitly specified. This reflects that fact that
internally the service manager deals in microsecond units only, and the bus properties are a relatively
low-level (binary) concept exposing this. The unit file settings on the other hand are relatively
high-level (string-based) concepts and thus support more user friendly time specifications which
default to second time units but allow other units too, if specified.
WatchdogTimestamp
and WatchdogTimestampMonotonic
contain
CLOCK_REALTIME
/CLOCK_MONOTONIC
microsecond timestamps of the
last watchdog ping received from the service, or 0 if none was ever received.
ExecStartPre
, ExecStart
, ExecStartPost
,
ExecReload
, ExecStop
, and ExecStop
are arrays
of structures where each struct contains: the binary path to execute; an array with all arguments to
pass to the executed command, starting with argument 0; a boolean whether it should be considered a
failure if the process exits uncleanly; two pairs of
CLOCK_REALTIME
/CLOCK_MONOTONIC
microsecond timestamps when
the process began and finished running the last time, or 0 if it never ran or never finished running;
the PID of the process, or 0 if it has not run yet; the exit code and status of the last run. This
field hence maps more or less to the corresponding setting in the service unit file but is augmented
with runtime data.
LimitCPU
(and related properties) map more or less directly to the
corresponding settings in the service unit files except that if they aren't set, their value is
18446744073709551615 (i.e. -1).
Capabilities
contains the configured capabilities, as formatted with
cap_to_text(3).
SecureBits
, CapabilityBoundingSet
,
MountFlags
also correspond to the configured settings of the unit files, but
instead of being formatted as strings, they are encoded as the actual binary flags they are.
ExecMainStartTimestamp
, ExecMainStartTimestampMonotonic
,
ExecMainExitTimestamp
, ExecMainExitTimestampMonotonic
,
ExecMainPID
, ExecMainCode
, ExecMainStatus
contain information about the main process of the service as far as it is known. This is often the same
runtime information that is stored in ExecStart
. However, it deviates for
Type=forking
services where the main process of the service is not forked off
systemd directly. These fields either contain information of the last run of the process or of the
current running process.
MainPID
and ControlPID
contain the main and control PID of
the service. The main PID is the current main PID of the service and is 0 when the service currently
has no main PID. The control PID is the PID of the current start/stop/reload process running and is 0
if no such process is currently running. That means that ExecMainPID
and
MainPID
differ in the way that the latter immediately reflects whether a main
process is currently running while the latter possible contains information collected from the last run
even if the process is no longer around.
StatusText
contains the status text passed to the service manager via a call
to
sd_notify(3).
This may be used by services to inform the service manager about its internal state with a nice
explanatory string.
Result
encodes the execution result of the last run of the service. It is
useful to determine the reason a service failed if it is in the "failed
" state (see
ActiveState
above). The following values are currently known:
"success
" is set if the unit didn't fail. "resources
" indicates that
not enough resources were available to fork off and execute the service
processes. "timeout
" indicates that a timeout occurred while executing a service
operation. "exit-code
" indicates that a service process exited with an unclean exit
code. "signal
" indicates that a service process exited with an uncaught
signal. "core-dump
" indicates that a service process exited uncleanly and dumped
core. "watchdog
" indicates that a service did not send out watchdog ping messages
often enough. "start-limit
" indicates that a service has been started too frequently
in a specific time frame (as configured in StartLimitInterval
,
StartLimitBurst
).
ControlGroup
indicates the control group path the processes of this service
unit are placed in.

Most of the properties map directly to the corresponding settings in socket unit files. As socket
units can include ExecStartPre
(and similar) fields which contain information about
processes to execute. They also share most of the fields related to the execution context that Service
objects expose (see above).
In addition to these properties there are the following:
NAccepted
contains the accumulated number of connections ever accepted on this
socket. This only applies to sockets with Accept
set to "yes
",
i.e. those where systemd is responsible for accepted connections.
Similarly NConnections
contains the number of currently open connections on
this socket. It only applies only to socket units with Accept
set to
"yes
".
Result
encodes the reason why a socket unit failed if it is in the
"failed
" state (see ActiveState
above). The values
"success
", "resources
", "timeout
",
"exit-code
", "signal
" and "core-dump
" have the same
meaning as they have for the corresponding field of service units (see above). In addition to that,
the value "service-failed-permanent
" indicates that the service of this socket failed
continuously.
FlushPending
specifies whether to flush the socket
just before entering the listening state. This setting only applies to sockets with
Accept=
set to "no
".

Target units have neither type-specific methods nor properties.
All device unit objects implement the org.freedesktop.systemd1.Device
interface (described here)

Device units only expose a single type-specific property:
SysFSPath
contains the sysfs path of the kernel device this object corresponds
to.
All mount unit objects implement the org.freedesktop.systemd1.Mount
interface (described here) in addition to the generic
org.freedesktop.systemd1.Unit
interface (see above).

Most of the properties map directly to the corresponding settings in mount unit files. As mount
units invoke the /usr/bin/mount
command, their bus objects include implicit
ExecMount
(and similar) fields which contain information about processes to
execute. They also share most of the fields related to the execution context that Service objects
expose (see above). In addition to these properties there are the following:
ControlPID
contains the PID of the currently running
/usr/bin/mount
or /usr/bin/umount
command if there is one
running, otherwise 0.
Result
contains a value explaining why a mount unit failed if it failed. It
can take the values "success
", "resources
",
"timeout
", "exit-code
", "signal
", or
"core-dump
" which have the identical meaning as the corresponding values of the
corresponding field of service unit objects (see above).
All automount unit objects implement the
org.freedesktop.systemd1.Automount
interface (described here) in addition
to the generic org.freedesktop.systemd1.Unit
interface (see above).
node /org/freedesktop/systemd1/unit/proc_2dsys_2dfs_2dbinfmt_5fmisc_2eautomount { interface org.freedesktop.systemd1.Automount { properties: @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly s Where = '...'; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly u DirectoryMode = ...; readonly s Result = '...'; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly t TimeoutIdleUSec = ...; }; interface org.freedesktop.DBus.Peer { ... }; interface org.freedesktop.DBus.Introspectable { ... }; interface org.freedesktop.DBus.Properties { ... }; interface org.freedesktop.systemd1.Unit { ... }; };
Most of the properties map directly to the corresponding settings in the automount unit files.
Result
knows the values "success
" and
"resources
" at this time. They have the same meanings as the corresponding values of
the corresponding field of the Service object.
All timer unit objects implement the org.freedesktop.systemd1.Timer
interface (described here) in addition to the generic
org.freedesktop.systemd1.Unit
interface (see above).
node /org/freedesktop/systemd1/unit/systemd_2dtmpfiles_2dclean_2etimer { interface org.freedesktop.systemd1.Timer { properties: @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly s Unit = '...'; @org.freedesktop.DBus.Property.EmitsChangedSignal("invalidates") readonly a(stt) TimersMonotonic = [...]; @org.freedesktop.DBus.Property.EmitsChangedSignal("invalidates") readonly a(sst) TimersCalendar = [...]; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly b OnClockChange = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly b OnTimezoneChange = ...; readonly t NextElapseUSecRealtime = ...; readonly t NextElapseUSecMonotonic = ...; readonly t LastTriggerUSec = ...; readonly t LastTriggerUSecMonotonic = ...; readonly s Result = '...'; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly t AccuracyUSec = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly t RandomizedDelayUSec = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly b FixedRandomDelay = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly b Persistent = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly b WakeSystem = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly b RemainAfterElapse = ...; }; interface org.freedesktop.DBus.Peer { ... }; interface org.freedesktop.DBus.Introspectable { ... }; interface org.freedesktop.DBus.Properties { ... }; interface org.freedesktop.systemd1.Unit { ... }; };
Unit
contains the name of the unit to activate when the timer elapses.
TimersMonotonic
contains an array of structs that contain information about
all monotonic timers of this timer unit. The structs contain a string identifying the timer base, which
is one of "OnActiveUSec
", "OnBootUSec
",
"OnStartupUSec
", "OnUnitActiveUSec
", or
"OnUnitInactiveUSec
" which correspond to the settings of the same names in the timer
unit files; the microsecond offset from this timer base in monotonic time; the next elapsation point on
the CLOCK_MONOTONIC
clock, relative to its epoch.
TimersCalendar
contains an array of structs that contain information about all
realtime/calendar timers of this timer unit. The structs contain a string identifying the timer base,
which may only be "OnCalendar
" for now; the calendar specification string; the next
elapsation point on the CLOCK_REALTIME
clock, relative to its epoch.
NextElapseUSecRealtime
contains the next elapsation point on the
CLOCK_REALTIME
clock in miscroseconds since the epoch, or 0 if this timer event
does not include at least one calendar event.
Similarly, NextElapseUSecMonotonic
contains the next elapsation point on the
CLOCK_MONOTONIC
clock in microseconds since the epoch, or 0 if this timer event
does not include at least one monotonic event.
Result
knows the values "success
" and
"resources
" with the same meanings as the matching values of the corresponding
property of the service interface.
All swap unit objects implement the org.freedesktop.systemd1.Swap
interface (described here) in addition to the generic
org.freedesktop.systemd1.Unit
interface (see above).

Most of the properties map directly to the corresponding settings in swap unit files. As mount
units invoke the
swapon(8) command,
their bus objects include implicit ExecActivate
(and similar) fields which contain
information about processes to execute. They also share most of the fields related to the execution
context that Service objects expose (see above). In addition to these properties there are the
following:
ControlPID
contains the PID of the currently running
swapon(8) or
swapoff(8)
command if there is one running, otherwise 0.
Result
contains a value explaining why a mount unit failed if it failed. It
can take the values "success
", "resources
",
"timeout
", "exit-code
", "signal
", or
"core-dump
" which have the identical meanings as the corresponding values of the
corresponding field of service unit objects (see above).

Most properties correspond directly with the matching settings in path unit files.
The others:
Paths
contains an array of structs. Each struct contains the condition to
watch, which can be one of "PathExists
", "PathExistsGlob
",
"PathChanged
", "PathModified
", or "DirectoryNotEmpty
"
which correspond directly to the matching settings in the path unit files; and the path to watch,
possibly including glob expressions.
Result
contains a result value which can be "success
" or
"resources
" which have the same meaning as the corresponding field of the Service
interface.
All slice unit objects implement the org.freedesktop.systemd1.Slice
interface (described here) in addition to the generic
org.freedesktop.systemd1.Unit
interface (see above).

Abandon()
may be used to place a scope unit in the "abandoned" state. This
may be used to inform the system manager that the manager that created the scope lost interest in the
scope (for example, because it is terminating), without wanting to shut down the scope entirely.
RequestStop
is sent to the peer that is configured in the
Controller
property when systemd is requested to terminate the scope unit. A program
registering a scope can use this to cleanly shut down the processes it added to the scope instead of
letting systemd do it with the usual SIGTERM
logic.
All properties correspond directly with the matching properties of service units.
Controller
contains the bus name (unique or well-known) that is notified when
the scope unit is to be shut down via a RequestStop
signal (see below). This is
set when the scope is created. If not set, the scope's processes will terminated with
SIGTERM
directly.
Job objects encapsulate scheduled or running jobs. Each unit can have none or one jobs in the execution queue. Each job is attached to exactly one unit.
node /org/freedesktop/systemd1/job/666 { interface org.freedesktop.systemd1.Job { methods: Cancel(); GetAfter(out a(usssoo) jobs); GetBefore(out a(usssoo) jobs); properties: @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly u Id = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly (so) Unit = ...; @org.freedesktop.DBus.Property.EmitsChangedSignal("const") readonly s JobType = '...'; readonly s State = '...'; }; interface org.freedesktop.DBus.Peer { ... }; interface org.freedesktop.DBus.Introspectable { ... }; interface org.freedesktop.DBus.Properties { ... }; };
Cancel()
cancels the job. Note that this will remove a job from the queue if
it is not yet executed but generally will not cause a job that is already in the process of being
executed to be aborted. This operation may also be requested via the CancelJob()
method of the Manager object (see above), which is sometimes useful to reduce roundtrips.
Id
is the numeric Id of the job. During the runtime of a systemd instance each
numeric ID is only assigned once.
Unit
refers to the unit this job belongs to. It is a structure consisting of
the name of the unit and a bus path to the unit's object.
JobType
refers to the job's type and is one of "start
",
"verify-active
", "stop
", "reload
",
"restart
", "try-restart
", or "reload-or-start
". Note
that later versions might define additional values.
State
refers to the job's state and is one of "waiting
" and
"running
". The former indicates that a job is currently queued but has not begun to
execute yet. The latter indicates that a job is currently being executed.
Example 1. Introspect org.freedesktop.systemd1.Manager
on the bus
$ gdbus introspect --system \ --dest org.freedesktop.systemd1 \ --object-path /org/freedesktop/systemd1
Example 2. Introspect a unit on the bus
$ busctl introspect org.freedesktop.systemd1 \ $(busctl call org.freedesktop.systemd1 \ /org/freedesktop/systemd1 \ org.freedesktop.systemd1.Manager \ GetUnit s systemd-resolved.service | cut -d'"' -f2)
Example 3. Introspect org.freedesktop.systemd1.Job
on the bus
$ gdbus introspect --system --dest org.freedesktop.systemd1 \ --object-path /org/freedesktop/systemd1/job/1292
