Munin::...::Daemon(3) User Contributed Perl DocumentationMunin::...::Daemon(3)

NAME
       Munin::Common::Daemon - utilities for daemons.

SYNOPSIS
       The following daemon-related features are supported:

       sd_notify: signal readiness of the daemon

SUBROUTINES
   emit_sd_notify_message
       Example:

	emit_sd_notify_message();

       Send a "ready" signal according to the "sd_notify" interface:

       1. check	whether	the environment	variable "NOTIFY_SOCKET" is defined
       2. remove this variable from the	environment (this interface is not
       propagated to children)
       3. send the string "READY=1" to the socket

       The function returns silently, if something fails.

       The function should be called as	soon as	the service is ready to	accept
       requests.   Calling  this  function is always safe - independent	of the
       caller supporting the "sd_notify" interface or not.

       Examples	for callers supporting the "sd_notify" interface:

       systemd:	see "Type=Notify" in "5" in systemd.exec
       start-stop-daemon: see "--notify-await" in "8" in start-stop-daemon

       See	   the		specification	       of	   "sd_notify"
       <https://www.freedesktop.org/software/systemd/man/sd_notify.html>   for
       further details of this interface.
