Munin::Common::Daemon(3pm) User Contributed Perl Documentation Munin::Common::Daemon(3pm)

NAME

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

SYNOPSIS

The following daemon-related features are supported:

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:

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