Can you please show us the pemissions on this file:

Code: Select all

ls -al /usr/lib/pnp4nagios/libexec/process_perfdata.pl

[imran_khan]

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.

[Box293]

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

[imran_khan]

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.

Hello,

I have corrected the path in /usr/local/nagios/var/objects.cache. Please find the verify command output. Please suggest me on the same.

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?

[imran_khan]

Hello,

Thanks for the reply.

I am getting Performance Data but still graph is not showing.

Performance Data: rta=2.443000ms;3000.000000;5000.000000;0.000000 pl=0%;80;100;0

Thanks,

What is the output of the following commands?

Code: Select all
