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?
