influxdbwriter ignores perfdata from passive checks

[kochd]

I noticed that influxdbwriter (v1) does not handle the perfdata of passive checks. v2 might be affected by this as well.

The passive check result is submitted using the API (https://icinga.com/docs/icinga-2/latest/doc/12-icinga2-api/#process-check-result)

The latest perfdata is available to icingaweb2 (when viewing the service) but it never gets send to the influxdb (I queried for it using the influx cli). There is no meassurement named 'lvm-thin' even tho I have a service named 'lvm-thin' which has perfdata aswell.

This tells me that the passive-check is correctly sending perfdata and it gets written into the ido but the influxwriter ignores it for some reason.

I found multiple people noticing the same, but it was never solved. (https://github.com/Icinga/icinga2/issues/6228 and in the community forums) I cant find any sort of log that gives more information about why it never gets written.

Imho this is an unintended behavior of influxdbwriter and therefore an actual bug.
