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).
