Hi Evgeni,
This is possibly behaviour that has been carried over from when the
textfile collectors were part of the prometheus-node-exporter package,
prior to upstream splitting them out into their own git repo.
If you look closely, you will see that the systemd timers (with the
exception of the apt collector) contain Condition... clauses, which will
prevent them from starting if the relevant hardware is not found on the
host. So yes, they are /enabled/ in the sense that systemd will process
them at boot, but they won't /start/ if not applicable (even if
attempted to be started manually) - and obviously if the timers do not
start, then the service units won't be automatically triggered either.
At most, you should get one log entry per timer, stating that it was not
started, e.g.:
May 08 07:50:53 vega systemd[1]:
prometheus-node-exporter-ipmitool-sensor.timer - Run ipmitool sensor
metrics collection every minute was skipped because of an unmet
condition check (ConditionDirectoryNotEmpty=/sys/class/ipmi).
Regards,
Daniel
