Nagios Support Forum

Hi All,

We have successfully added monitoring services but after several checks, we don't see performance data on graphs.

Rrd and xml files are updated. We get no error both in npcd.log and perfdata.log.
You can see below a screenshot of the "advanced tab"
We are running Nagios XI 2012R2.9 on a cent0s6.3

Thanks

Could you increase the log level/debugging and check the logs again? The faq entry details the necessary steps to increase perfdata and npcd logging levels.

As you suggested, i have increased perfdata and npcd logging verbosity

I have not found any error in my log files (in attachment)

I can see in the perfdata.txt log that the perfdata files are being updated.

Can you please do the following: Do any graphs appear for the host nagios.lan ? Like the http service?

Hi there,
we found the cause of the problem. It was the heartbeat set to a lower value than the check interval.
The default value of the heartbeat was 8460 as indicated in the /usr/local/nagios/etc/pnp/process_perfdata.cfg but it was too much higher for some our checks so we decreased it to 120.
After the change, all the graphs created for checks having check_interval < 120 have not worked.
We solve the problem by increasing each RRD heartbeat via rrdtool.

Is it possible to set the RRD heartbeat when a service is being created?


Thanks.

You can edit the rra to change the rrd creation values for all newly created rrds by editing the file /usr/local/nagios/etc/pnp/rra.cfg.

Hi,
we would like to set different heartbeats for different RRDs

Well, all rrds are created with that same rra. If you need to set different values for different rrds, you will need to do it by hand or make a pseudo intelligent script to do so.
