ImqServerPlugin class

Traces incoming @imqueue RPC calls — the SERVER half of the imq integration, producing the imq.response span.

Signature:

export declare class ImqServerPlugin extends TracingPlugin

Extends: TracingPlugin

Remarks

Subscribes to apm:imq:response:{start,error,finish} — the channels the instrumentation in ./instrumentation publishes from the service's beforeCall/afterCall hooks.

This is the half that continues a caller's trace, and the half whose span becomes the ambient parent for everything the service method does. Instantiated by the tracer through ImqPlugin, not directly; switch it off with tracer.use('imq', { server: false }).

Properties

Property	Modifiers	Type	Description
component	`static`	string	Component tag reported on every span, `'imq'`.
id	`static`	string	Integration this plugin belongs to, `'imq'`.
kind	`static`	string	Datadog span kind: this half handles calls.
operation	`static`	string	Operation half, `'response'` — the middle segment of the `apm:imq:response:*` channels this subscribes to.
type	`static`	string	Datadog span type — RPC over a queue is messaging.

Methods

Method	Modifiers	Description
error(ctx)		Marks the span as failed. The span itself is finished by `finish()`, which the instrumentation always publishes.
finish(ctx)		Finishes the span of a handled call.
start(ctx)		Starts the span for an incoming call, continuing the caller's trace when the request carries a propagated context.
