Some metrics are reported only if the respective configuration are enabled:
systemd.service.cpu_time_consumed requires Systemd configuration CPUAccounting to be enabled
systemd.service.memory_usage requires Systemd configuration MemoryAccounting to be enabled
systemd.service.task_count requires Systemd configuration TasksAccounting to be enabled
Some metrics are only available from specific version of Systemd:
Returns OK if Systemd is reachable, CRITICAL otherwise.
Statuses: ok, critical
systemd.system.state
Returns OK if Systemd’s system state is running. Returns CRITICAL if the state is degraded, maintenance, or stopping. Returns UNKNOWN if the state is initializing, starting, or other.
Statuses: ok, critical, unknown
systemd.unit.state
Returns OK if the unit active state is active. Returns CRITICAL if the state is inactive, deactivating, or failed. Returns UNKNOWN if the state is activating or other.
Statuses: ok, critical, unknown
systemd.unit.substate
Returns OKCRITICAL or UNKNOWN based on the substate of the unit and the user-provided mapping in systemd.d/conf.yaml.
