Informs systemd about changed daemon state. This takes a number of
newline separated environment-style variable assignments in a
string. The following variables are known:
- READY=1 Tells systemd that daemon startup is finished (only
- relevant for services of Type=notify). The passed
- argument is a boolean "1" or "0". Since there is
- little value in signaling non-readiness the only
+ MAINPID=... The main PID of a daemon, in case elogind did not
+ fork off the process itself. Example: "MAINPID=4711"
+
+ READY=1 Tells elogind that daemon startup or daemon reload
+ is finished (only relevant for services of Type=notify).
+ The passed argument is a boolean "1" or "0". Since there
+ is little value in signaling non-readiness the only
value daemons should send is "READY=1".
+ RELOADING=1 Tell elogind that the daemon began reloading its
+ configuration. When the configuration has been
+ reloaded completely, READY=1 should be sent to inform
+ elogind about this.
+
+ STOPPING=1 Tells elogind that the daemon is about to go down.
+
STATUS=... Passes a single-line status string back to systemd
that describes the daemon state. This is free-form
and can be used for various purposes: general state
BUSERROR=... If a daemon fails, the D-Bus error-style error
code. Example: "BUSERROR=org.freedesktop.DBus.Error.TimedOut"
- MAINPID=... The main pid of a daemon, in case systemd did not
- fork off the process itself. Example: "MAINPID=4711"
-
WATCHDOG=1 Tells systemd to update the watchdog timestamp.
Services using this feature should do this in
regular intervals. A watchdog framework can use the
timestamps to detect failed services. Also see
sd_watchdog_enabled() below.
+ WATCHDOG_USEC=...
+ Reset watchdog_usec value during runtime.
+ To reset watchdog_usec value, start the service again.
+ Example: "WATCHDOG_USEC=20000000"
+
FDSTORE=1 Store the file descriptors passed along with the
message in the per-service file descriptor store,
and pass them to the main process again on next
invocation. This variable is only supported with
sd_pid_notify_with_fds().
+ FDSTOREREMOVE=1
+ Remove one or more file descriptors from the file
+ descriptor store, identified by the name specified
+ in FDNAME=, see below.
+
+ FDNAME= A name to assign to new file descriptors stored in the
+ file descriptor store, or the name of the file descriptors
+ to remove in case of FDSTOREREMOVE=1.
+
Daemons can choose to send additional variables. However, it is
recommended to prefix variable names not listed above with X_.
