2.1.0p30

8 vanished services
The script should run an the CheckMK server, but removes other services.
All local script services after that part are lost.

Even this does not work. I lose services on the server, that runs the checkmk agent.

Can somebody please help me?

You cannot generate piggyback data in a Local Check.
Local Checks must only print out local check lines.

Move this script to the plugins folder.

Thank you that was the solution. But I am using piggyback on other hosts als local scripts. I don´t understand, why it is working.

The issue is that other local checks are execute after the script that outputs the piggyback data.
The lines from these script are not in a local section any more and are lost.

This is why it is important that a script in the local directory of the agent only outputs Local Check lines and nothing else.

On your other hosts the script may be the last to be executed in the local directory.

Piggyback cannot be nested into a local section. Use a spool file as workaround or move the piggyback script from the local checks to the regular plugins.
