Hello,

There is no directory pnp4nagios under /usr/lib.

I am using /usr/local/pnp4nagios/libexec/process_perfdata.pl file/path not /usr/lib/pnp4nagios/libexec/process_perfdata.pl

Thanks,
Imran Khan.

I think you need to edit your commands.cfg file and change any references of:
/usr/lib/pnp4nagios/libexec/process_perfdata.pl
to:
/usr/local/pnp4nagios/libexec/process_perfdata.pl

Hello,

I did not set /usr/lib/pnp4nagios/libexec/process_perfdata.pl in command.cfg but I dont know why getting this error.

Command:-
define command{
command_name process-service-perfdata-file
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/service-perfdata
}
define command{
command_name process-host-perfdata-file
command_line /usr/local/pnp4nagios/libexec/process_perfdata.pl --bulk=/usr/local/pnp4nagios/var/host-perfdata
}

Thanks,
Imran Khan.

That looks much better. The only warnings you are getting are for the majority of your hosts and services not returning performance data, which could be perfectly normal depending on your setup. Since your paths appear to be correct now, what is currently happening that is causing issues?
