New Munin Plugin for Systemd released

Today my plugin systemd_mem got merged into Munin’s contribution repository. It monitors the memory usage of systemd services as calculated by systemd itself.

With a little hack, you can also let yourself be notified if a services stops running: just set the lower warning limit to 1 byte.

You can check the plugin out in Munin’s official plugin gallery.


  1. Hi Paul,

    Could you tell me how i set the lower warning limit to 1 byte? I’ve been searching but can’t find anything..


  2. Take the Apache2 for example. Adding the following to munin.conf

    systemd_mem.apache2.warning 1:1610612736

    will warn outside of 1 byte and 1.5GB.
