Struct DurationStats

Source

pub struct DurationStats { /* private fields */ }

Expand description

DurationStats tracks:

durations an escrowing component was executing (started_durations/histogram/MONIKER)
durations an escrowing component stayed stopped in-between two executions (stopped_durations/histogram/MONIKER)

The tracking begins the first time a component sends an escrow request. Subsequently, started/stopped durations will be tracked regardless if that component keeps sending escrow requests.

The duration is measured in ticks in the Zircon monotonic clock, hence does not account into times the system is suspended.

Implementations§

Source §

impl DurationStats

pub fn new(node: Node) -> Self

Creates a new duration tracker. Data will be written to the given inspect node.
