Is there now a variant built into Checkmk, for example to check whether a restart of Ubuntu is necessary?
Unfortunately, I could not find anything.
If not then I’ll build my own check, that wouldn’t hurt either 
Thanks a lot.
Hallo,
the yum check for rpm distros has an option to warn if a reboot necessary.
I don t know if the apt check works similar.

There is no such check build into Checkmk. But you can use this local check script:

thats a very nice page, didn’t know that before. Thanks
I will have a look.
Ubuntu & Debian have an optional package called needrestart.
It checks if processes/daemons/containers/whole OS need a restart. And it has a fancy -p switch to give its output in a Nagios-compatible way.
So I use it as a cached mrpe check:
Need_Restart (interval=180) /usr/sbin/needrestart -p
Also it hooks into apt/dpkg and so it asks you after an update, if you want to restart those daemons.

I will give this package a try.
Since we mainly use Ubuntu I think I can use it on any server we manage.
