Nagios Support Forum

Dear Team,
We are observing no data in performance graphs for all services and hosts.
Also observing that no graph icon showing newly adding servers into monitoring.
Please refer below attached screenshot for more details.

Can you help to advise quickly as no performance stats available for services and hosts in monitoring?

Hi,

Welcome to the Customer Support Forum!

This could happen if the npcd service is not running, so let's check that first. If that's running, then please step through the guide below to check the spool count on the files. It might be necessary to increase the default thresholds, explained in the guide as well and let me know if the issue is resolved.

Hope these details helpful to advise further.

Thank you.

Hi,

Those errors may be logged if the file was processed by another thread. Are the performance graphs working for any of the services?

If not, let's increase the log level on NPCD. You can enable debugging for npcd by setting:
in /usr/local/nagios/etc/pnp/process_perfdata.cfg and then restart the npcd process. Then tail the log file and post any errors to the thread. Also, how's the count of spooled files looking? Regards,
Benjamin

Hi Benjimin,
All Graphs are working fine after above mentioned settings put in place.

Thank you.

Best Regards,
Jagan
