Introduction

Allows for the collection of metrics in relation to how an application interacts with Orbit.

    • orbit.actors.chainresponsetime[actor:%s,method:%s]

Instructions

If no MetricRegistry is provided to the Extension or InvocationHandler then it will construct a MetricRegistry and make it available by calling the getter method. Otherwise the provided MetricRegistry will be used.

MetricRegistry metricRegistry = new MetricRegistry();

OrbitMetricsActorExtension actorExtension = new OrbitMetricsActorExtension(metricRegistry);
OrbitMetricsMessagingExtension messagingExtension = new OrbitMetricsMessagingExtension(metricRegistry);

OrbitMetricsInvocationHandler invocationHandler = new OrbitMetricsInvocationHandler(metricRegistry);

Builder builder = new Stage.Builder();
builder.extensions(actorExtension, messagingExtension);
builder.invocationHandler(invocationHandler);
Stage stage = builder.build();
stage.start();
