Empty perfdata files in /var/spool/icinga2/perfdata directory

Icinga 2

Hi Team,

This morning, I have noticed a strange behaviour in my icinga2 environment.

Below are the version details.

Apache - 2.4.41
Icinga2 - 2.11.2
Icingaweb2 - 2.7.3
PHP - 7.3.13
OS - RHEL 7.6

Till last evening i could able to see the perfdata in icingaweb2 console in pnp4nagios graph, when i checked this morning i have noticed that there is no data in pnp4nagios graph.

I initially suspected that, it is becuase of pnp4nagios issue. but after investigating i have realized that icinga2 is creating empty files in /var/spool/icinga2/perfdata directory.

I could see the performance data under the performanc data label in icingaweb2. these checks were showing data till last evening.

I have enabled debuglog and it is picking the perfdata values as per the check output but while writing to perfdata directory…these are empty files.

Any suggestions to troubleshoot this issue?

What does df tell you about available disk space?

The perfdata feature in the webinterface is enabled?

It is disabled. Just now I enabled it. Looks like it is working…Let me monitor this for sometime and update here.

I have enabled the perfdata feature in the backend using command and also I can see this perfdata in enabled feature list.

Can you please tell me where to check this in the backend conf files?

I don’t believe enabled/disabled features can be controlled from a
configureation file (and therefore there’s nowhere to look to find out what
setting they have) - this is why the “icinga2 feature” command exists.

I’m not a developer, but I suspect this means the enabled/disabled settings
are stored in the private Icinga database.

You can find out which features are enabled using the command “icinga2 feature
list”.

I mean I have disabled/enabled using “icinga2 feature” command. Still it was not showing data. But after you post, I have checked the icingaweb2 log and noticed that one of my collegue has disabled it from GUI…
After enabling this from GUI I can confirm that again I started seeing data.

Hence closing this thread.

Thanks a lot for the response and troubleshooting.
