Fields

CommandDuration

Histogram of command-handling latency in milliseconds for commands dispatched through the outbox worker. Tagged with RequestType and Outcome (success or failure).

public static readonly Histogram<double> CommandDuration

Field Value

Histogram<double>

Remarks

It is not end-to-end command latency, despite the name. The in-process mediator dispatch path records nothing here, so a host that dispatches commands directly sees an empty histogram and a host that does both sees only half its traffic. Read it as "outbox command latency". Covering the in-process path would change what the instrument means and is a separate decision.

EventSourceAppendConflicts

Counter that tracks optimistic-concurrency conflicts encountered when appending events to a stream (write store).

public static readonly Counter<long> EventSourceAppendConflicts

Field Value

Counter<long>

EventsAppended

Counter of domain events appended to an event stream. Tagged with EventType and AggregateType so operators can see per-event-type and per-aggregate write throughput.

public static readonly Counter<long> EventsAppended

Field Value

Counter<long>

Meter

The shared Meter instance.

public static readonly Meter Meter

Field Value

Meter

MeterName

The meter name — "Stratara.Service".

public const string MeterName = "Stratara.Service"

Field Value

string

OutboxEntriesPublished

Counter of outbox entries successfully published by the outbox worker. Tagged with OutboxKind (command or event) so operators can distinguish command-dispatch from event-bundle throughput.

public static readonly Counter<long> OutboxEntriesPublished

Field Value

Counter<long>

ProjectionBundleDuration

Histogram of projection event-bundle processing latency in milliseconds, measured around the projection worker's per-bundle dispatch. Tagged with Outcome (success or failure).

public static readonly Histogram<double> ProjectionBundleDuration

Field Value

Histogram<double>

ProjectionEventsProcessed

Counter of events dispatched to projection handlers. Tagged with EventType and Outcome (success or failure) so operators can see per-event-type projection throughput and failure rates.

public static readonly Counter<long> ProjectionEventsProcessed

Field Value

Counter<long>

SagaBundleDuration

Histogram of saga event-bundle processing latency in milliseconds, measured around the saga worker's per-bundle dispatch. Tagged with Outcome (success or failure).

public static readonly Histogram<double> SagaBundleDuration

Field Value

Histogram<double>

SagaEventsProcessed

Counter of events dispatched to saga handlers. Tagged with EventType and Outcome (success or failure) so operators can see per-event-type saga throughput and failure rates.

public static readonly Counter<long> SagaEventsProcessed

Field Value

Counter<long>

SagasInFlight

Up/down counter tracking the number of saga event-bundles currently in flight (being processed across all saga-worker subscriptions). A persistently rising value indicates the saga lane cannot keep up with the inbound event rate.

public static readonly UpDownCounter<long> SagasInFlight

Field Value

UpDownCounter<long>
