Issues with Multiple Perfdata graphs for a single service

[weapon]

I am having some issues with checks that return multiple lines of perfdata, and therefore have multiple graphs for a single service.

I have found that nagios does not pay attention to the label for the performance data, only the order which it is returned in - therefore if you change the order the graphs have the wrong data in them. This is not my issue though, I can work around that. What I have found is that when the number of lines of perfdata changes (only noticed when it reduces, not sure if it occurs when it increases), no more data gets logged for that service.(see attached images - perfdata was being generated at the time, just not graphed)

I have traced it through and I think that process_perfdata.pl is the issue. It does not seem to have a section for handling changing the number of data sources. Is this a bug or limitation in Nagios or rrd, or am I doing something wrong.

Unfortunately for some reason my perfdata.log has stopped working. Nagios appears to be configured for bulk mode (without NCPD) for loading the perfdata. The /usr/local/nagios/var/spool/xidpe directory is empty.

I am running Nagios 2012R2.7, but will be upgrading to the latest 2014 next week. I think this was installed by the VMImage.

Thanks in advance,

David

I believe the issue is caused by the fact that the rrds (the storage mechanism for perfdata) do not support a dynamic number of data sources, and if the number of data sources change, graphing will cease to function correctly. You can try running the "fix_ds_quantity.sh" script to fix the issue:

Let us know if this helped.

Yes, this helped (or the upgrade to 2012.14R2.6)

But...

I have lost my pnp4nagios graphs, whilst the new graphs are nice, they are missing some functionality (multiple separate graphs for services with warning and critical lines)

Is there an easy way to get the pnp4nagios graphs back, or working side by side?

You can turn off highcharts and use PNP instead.

Admin > System Config > Manage System Config
Use Highcharts for Perfdata Graphs = UN check this box
Click Update Settings

Thanks for that.

I think that is all working now!
