Hi,

Your analysis is correct. The check_openmanage plugin's check of the log
content is limited to counting the number of critical, warning and ok
messages. It doesn't do any log parsing. The intended usage of the log
checking is as a precausion, if you're concerned about missing some
temporary problem. After all, the plugin does active checking and will
only report the state of the hardware right now.

In your case I think that the easiest solution would be to stop using
the log checking with check_openmanage, and either use a fully fledged
log parsing plugin (such as check_logfiles) or write your own simple
plugin where you just filter out the certificate stuff.
