Nagios Support Forum

Hi, I have found I have no data in my perf charts. First step was to check npcd service is running, and upon running servicectl status npcd, I find it running, but issuing these errors in repetition, about 20 times:

Feb 20 09:48:38 nagios.pace.gatech.edu npcd[1639969]: Can't locate warnings.pm: /usr/local/lib64/perl5/5.32/warnings.pm: Permission denied at /usr/local/nagios/libexec/process_perfdata.pl line 27.
Feb 20 09:48:38 nagios.pace.gatech.edu npcd[1639969]: BEGIN failed--compilation aborted at /usr/local/nagios/libexec/process_perfdata.pl line 27.

lines 1-41

It seems data stopped being added to any charts on 1/28. No upgrade or changes to Nagios were made.

Why is npcd throwing this error? Thanks

You may want to see if warnings.pm exists at the location in the message and run process_perfdata.pl to see the output. Then troubleshoot.
