Struct UnitsCollectionTimings

}

Inner timing breakdown for the units collector D-Bus phases.

Helps locate which step of unit collection dominates wall time when the units collector is the slowest one in MonitordStats::collector_timings.

Fields

list_units_ms: f64

Time for the systemd ListUnits D-Bus call (one batched call returning all units).

unit_files_ms: f64

Time for filesystem unit file stats collection (runs concurrently with list_units).

per_unit_loop_ms: f64

Time spent in the per-unit parse loop, including any per-unit D-Bus calls (timer property fetches, state stats, service stats).

timer_dbus_fetches: u64

Number of timer units whose properties were fetched via D-Bus this run.

state_dbus_fetches: u64

Number of unit state D-Bus fetches this run (when state_stats_time_in_state is enabled).

service_dbus_fetches: u64

Number of per-service D-Bus property fetches this run.

slowest_units: Vec<(String, f64)>

Slowest units (by per-unit collection duration, descending) this run, truncated to units.slowest_units_count. Empty when disabled (count 0).

Trait Implementations

impl Clone for UnitsCollectionTimings

fn clone(&self) -> UnitsCollectionTimings

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnitsCollectionTimings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UnitsCollectionTimings

fn default() -> UnitsCollectionTimings

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UnitsCollectionTimings

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UnitsCollectionTimings

fn eq(&self, other: &UnitsCollectionTimings) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UnitsCollectionTimings

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
