Nagios Support Forum

Hi All

I have a trial of Nagios XI running in the following configuration:

- 2011R1.7 running as a VM on VMWare ESXi 4.1 (downloaded VMWare Virtual Machine from Nagios site and converted to a Virtual Server in ESXi)
- 64 bit
- No Special customizations

I have about 12 Centos 5.6 and Redhat 6.1 Servers and 2 Windows 2003 hosts monitored.
For the last few weeks none of the performance graphs for any of the servers show data. I can see that the perf data is being collected as seen in the Advanced tab in the Host Status detail (see screenshot). I have tried the following:

- Restarted all Nagios Services
- Restarted Nagios server itself
- Gone to Core Config Mgr, went to Host Management, opened up each host and checked the Process perf data 'on' button (looks like it was set to 'skip' by default).
- Read through the forums

Can you please help? We are going to be purchasing Nagios and I need to have these graphs available for gathering monthly metrics.

thanks
Brett

Can you see if the npcd process is still running by typing this into the command line of your nagios server?

service npcd status

yes, it shows it running:

[root@usscnagios ~]# service npcd status
NPCD running (pid 1579).

Hmm, is the npcd log showing anything strange/errors? Its at /usr/local/nagios/var/npcd.log. Start at the bottom and look for errors.
