Nagios Support Forum

Hi Team,

I've configured an service in Nagios.
Nagios was not receiving Performance Data from the query, SO i customised the query to print performance data as well.

So now i'm getting output like below: The query output i customized to get above output & is working for all the servers & even this server [oslas037] too .
But the problem is whenever i'm changing Service Name to Active Sessions its not reading Performance Data.
But if Service name is Active Sessions Test or something else, it's displaying performance data.

Please help me & let me know what i'm doing wrong or if there something in cache etc.

I'm attaching two sanpshot of performace grapgh which are of same server oslas037 with same commands but different service name.

Hello, @hoegh. This perfdata syntax is correct:

JMX CRITICAL activeSessions=420 |'activeSessions'=420;100;300

Did you create a new service check definition in XI that is using this new command or did you just change the service name in the existing check?

The RRD file likely got corrupted. Can you run the following command and then upload the support.txt file from the /tmp/ folder?

ls -ld /usr/local/nagios/var/spool/perfdata > /tmp/support.txt

I had created first service with name Active Sessions, but performance graph was missing. So i created another Service named Active Sessions test to test my performance graph.
Once it worked, i tried renaming it to Active Sessions but again performance graph was not visible.
I tried deleting Active Sessions service anme, recreating new service with name Active Sessions.
But whenever i'm using Active Sessions as service name, Graph is not coming.

ls -ld /usr/local/nagios/var/spool/perfdata > /tmp/support.txt

I've attached support.txt file. please have a look.

@hoegh, Sorry I've given you the wrong command. I wanted you to run the following command so I could see the list of RRD and XML files.

ls -lr /usr/local/nagios/var/spool/perfdata

This could cause corruption to the rrd file. There's only 1 rrd file that gets created for each service. Changing the service definition will change the data coming to the RRD file and may populate the wrong fields.

My recommendation would be to look for the Active Sessions RRD and XML files in the /usr/local/nagios/var/spool/perfdata folder, delete them and wait 15 minutes for nagios to generate new files.

I deleted rrd & xml file located at /usr/local/nagios/share/perfdata/
issue resolved.


Please Close this thread.
Thanks

@hoegh, Awesome, I'll be closing this thread as resolved.
