The plugins for RHEL 7 are compiled on CentOS 7 using Python 3.8. Your error message points to Python 3.9. Looks like your binaries were installed from the wrong repo path or weren't updated at all (just a guess).

I also tested all RHEL OS packages again - installed them according to https://repo.linuxfabrik.ch/monitoring-plugins/ in fresh VMs and ran /usr/lib64/nagios/plugins/cpu-usage. The results:

Hi I've checked some other RHEL7 systems and they all seem to have the same problem using the official RHEL 7 repos and the linixfabrik repo. Looking into it.. Found some information here https://access.redhat.com/discussions/3244811 definatley don't want to modify the RHEL7 native glibc version. Not sure why CentoS 7 does not have this problem but most of our systems are RHEL7/RHEL8.

Done a fresh install of rhel7 and recompiled from source. It is now working.

I have now compiled and packaged the plugins for RHEL 7 on a RHEL 7 instead of CentOS and uploaded it to our repo server. Maybe you can give the new rpm (-2) a try.

Will do.

Hi Markus, the rpm you linked above works however the package in the repo does not.

markuslf commented 1 year ago

Hm... We tweaked the rpm again (in the post-install script, regarding https://github.com/Linuxfabrik/monitoring-plugins/issues/674) and added a new /7Server symlink to the repo. Installation as described here works for us on both CentOS 7 and RHEL 7. You may want to try a yum clean all first.

The repo comes down with version 2023051201-3 so I am sure it has been updated however this version does not work on any of our rhel7 servers. It is not a major problem for us because we have created a seperate internal repo with the version which works maybe we wait to get some feedback from others in the community.

Ok, closing for now. Thanks for testing and your feedback.
