What the meter has seen since the process started.

Percentiles are bucket upper bounds capped at the observed maximum, so they over-estimate by at most a factor of two and never under-estimate.

Fields

gate_us: u64

The gate these counts are measured against, microseconds.

observed_ops: u64

Accepted ops measured. Rejections are not ops and are not counted.

decision_p50_us: Option<u64>

Median dequeue -> append: the gate as literally written.

decision_p99_us: Option<u64>

99th percentile dequeue -> append.

decision_max_us: u64

Slowest dequeue -> append observed.

decision_breaches: u64

Accepted ops whose append alone reached the gate.

durable_p50_us: Option<u64>

Median dequeue -> acknowledgement, durability barrier included: what a submitter waits out.

durable_p99_us: Option<u64>

99th percentile dequeue -> acknowledgement.

durable_max_us: u64

Slowest dequeue -> acknowledgement observed.

durable_breaches: u64

Accepted ops that reached the gate through the barrier. This is the breach count the lag log records.

pending_breaches: usize

Breaches recorded but not yet drained to the operator’s lag log.

Trait Implementations

impl Clone for LagReport

fn clone(&self) -> LagReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LagReport

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

Formats the value using the given formatter.

impl PartialEq for LagReport

fn eq(&self, other: &LagReport) -> 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.
