Graphs not showing in Dashboard

[dwhitfield]

rm /usr/local/nagios/share/perfdata/crgnas1.bose.com/Check_Volumes.rrd should get rid of the rrd file, but note that means you lose this data. The rrd file should recreate itself.

You could also just mv the rrd file and then it should also start repopulating.

Please let us know if you have any questions about this.

You may also find this information helpful if you want to preserve the existing data with the newly generated rrd file:

We renamed the rrd file but it was not creating another file....so we had to manually re-create it and still graphs are not showing.

Lets turn on debugging for the process_perfdata command and see if we can get any details on why the data is not populating the graph.
Edit this file

Code: Select all

/usr/local/nagios/etc/pnp/process_perfdata.cfg

Change the following from

Code: Select all

LOG_LEVEL = 0

to

Code: Select all

LOG_LEVEL = 2

Save the file and restart nagios by running

Code: Select all

service nagios restart

Then delete both of the .xml and .rrd files bu running

Code: Select all

rm /usr/local/nagios/share/perfdata/crgnas1.bose.com/Check_Volumes.rrd
rm /usr/local/nagios/share/perfdata/crgnas1.bose.com/Check_Volumes.xml

Let the system run that check a few times and upload the following log file so we can see the errors on why it is not recreating the graphs for you.

Code: Select all

/usr/local/nagios/var/perfdata.log

I have enabled the Log kevel to 2 and moved the rrd and xml files to tmp directory.

[dwhitfield]

if /usr/local/nagios/var/perfdata.log is too large to upload, tail -100 /usr/local/nagios/var/perfdata.log will likely be enough.

Make sure the check runs a few times before uploading the log.

we fixed the issue by using a different plug in

you can close this post.

It might be useful for others to know which plugin you used. Glad you found something working!
