Nagios Graphs for newly added plugin

[kingston]

Hi

I have configured one of my RHEL 5.3 x86_64 bit server as a Nagios monitoring host and the nagios core version installed is 3.5.0.
My environment has OEL 5.3, RHEL 5.3/6, SLES 10 and HPUX 11i V3 servers

Recently i have added check_memory plugin in OEL and in RHEL servers which is working fine. But when it comes to graphs, it is not showing any graphs.
I have checked rrd directory for the relavant rrd files under "each server's" directory but found there is no relavant entry is created.

I did delete all the contents under /var/nagios/rrd directory to check whether it is creating new files for the newly added plugins but failed.

Please let me know how to enable graphs for newly added plugins.

Regards
Kingston S

It is possible the plugin you added doesn't return performance data, and a graph would not be generated.

If you look at the service status detail page, on the advanced tab is there performance data?

So, as you said, my memory plugin is not sending any performance data to the graph. Could you also please tell me how to check plugins for performance data compatibility?

Well, this is totally dependent on the author of the plugin, though there are a few key points to look for as are specified here:

http://nagios.sourceforge.net/docs/3_0/perfdata.html
https://nagios-plugins.org/doc/guidelines.html

Specifically looking for direct output pipes contained in an exit string or block would be a heavy indicator of it's presence, that, and looking at the usage output of a plugin, and what it actually returns when ran.
