CheckMK 2.0.0 redis checks cannot create RRD files

I’m using the CMC core with default RRD settings “One RRD per host/service”.

I don’t think so
The error message shows that it tries to create RRDs inside the PNP4Nagios folder structure.

@Notausstieg0309

Can it be, that the semicolon in the service description

Yes this is an illegal character and not handled correctly.
The mentioned commit is not exactly the problem as this is only the agent output.
The real problem lies inside the check and how the check builds the service description or then later PNP4Nagios who should filter the service descriptions the correct way.

First step i would try is

• create an empty site with RRD handling by the CMC core
• only add one host that is using these redis checks
• check if there are files created inside ~/var/check_mk/rrd/ and graphs shown
