Munin::...::Daemon(3)

πŸ“¦ version 2.0.78, in nixos 26.05, nixpkgs unstable

okay so bestie, welcome to the Munin::...::Daemon(3) page β€” it's part of User Contributed Perl Documentation, and it's lowkey all about daemon utilities. Buckle up, it's short but useful ✨

πŸ’– NAME πŸ’–

Munin::Common::Daemon β€” utilities for daemons.

✨ SYNOPSIS ✨

Here's the daemon-related feature it supports:

  • sd_notify: signal readiness of the daemon 🫢

🌸 SUBROUTINES 🌸

πŸŽ€ emit_sd_notify_message πŸŽ€

Example:

emit_sd_notify_message();

It sends a "ready" signal using the sd_notify interface. The whole glow-up is literally this:

  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

If something fails, it returns silently β€” no drama, no error 😢

Call it as soon as the service is ready to accept requests. Calling it is always safe β€” independent of whether the caller supports the sd_notify interface or not. No cap πŸ’…

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.


okay that's the whole page, bestie 🫢 source/version is perl v5.42.3, dated 1980-01-01, and it's for Munin::...::Daemon(3) β€” iconic, mwah πŸ’‹
