Module units 

units module

All main systemd unit statistics. Counts of types of units, unit states and queued jobs. We also house service specific statistics and system unit states.

Structs

ListedUnit

Representation of the returned Tuple from list_units - Better typing etc.

ServiceStats

Per-service metrics from the org.freedesktop.systemd1.Service and Unit D-Bus interfaces. Ref: https://www.freedesktop.org/software/systemd/man/org.freedesktop.systemd1.html

SystemdUnitActiveStateIter

An iterator over the variants of SystemdUnitActiveState

SystemdUnitLoadStateIter

An iterator over the variants of SystemdUnitLoadState

SystemdUnitStats

Aggregated systemd unit statistics: counts by type, load state, active state, plus optional per-service and per-timer detailed metrics

UnitStates

Per-unit state tracking combining active state, load state, and computed health. Ref: https://www.freedesktop.org/software/systemd/man/org.freedesktop.systemd1.html

Enums

MonitordUnitsError

SystemdUnitActiveState

Systemd unit active states representing the unit’s runtime lifecycle. Ref: https://www.freedesktop.org/software/systemd/man/org.freedesktop.systemd1.html

SystemdUnitLoadState

Functions

is_unit_unhealthy

Check if we’re a loaded unit and if so evaluate if we’re acitive or not If we’re not Only potentially mark unhealthy for LOADED units that are not active

parse_state

Parse state of a unit into our unit_states hash

parse_unit_state

Pull all units from dbus and count how system is setup and behaving

update_unit_stats

Async wrapper than can update uni stats when passed a locked struct
