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.

CommandDurationName

Instrument name command.duration; see CommandDuration.

public const string CommandDurationName = "command.duration"

Field Value

string
