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.

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..
TIA!
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.
