Nagios Support Forum

Hi everbody,

I'm using Nagios Core 3.4.1 on a CentOS 6.5, and Nagvis 1.7.10 to display my supervised hosts on a big screen.
This morning, i found my Nagvis screen with the error " The needed parameter "perfdata" is missing'.

nothing was changed on the configuration, i checked out my storage and everything was ok. but when i reloaded Nagios, the error message disappeared and everything's back to normal.

Any idea about this ?

Thank you...

Hi @Anasstaze,

In Nagios Core, perfdata is temporarily stored in spool directory before being written to RRD files used to generate visualizations. Since your problem was resolved when restarting, it's possible a service or daemon related to this process had stopped or was unable to process perdata.

If you experience this issue again, we can take a look at the log files and try to find the source of the problem. You can enable debug logging in /usr/local/nagios/etc/pnp/process_perfdata.cfg for perdata and messages will be written to /usr/local/nagios/var/perfdata.log

For more info, we have a knowledgebase article that explains log files architecture in Nagios XI and Nagios Core:
