Orleans.TelemetryConsumers.Datadog

Orleans integration package for Datadog.

telemetry consumers

There are six telemetry consumer interfaces extending the ITelemetryConsumer interface:

• IMetricTelemetryConsumer
• IDependencyTelemetryConsumer
• IEventTelemetryConsumer
• IExceptionTelemetryConsumer
• IRequestTelemetryConsumer
• ITraceTelemetryConsumer

At the moment, only IMetricTelemetryConsumer is supported and it's implemented by DatadogMetricTelemetryConsumer.

DatadogMetricTelemetryConsumer

Implements IMetricTelemetryConsumer interface. Provides basic metrics like grain count, information about application requests, messaging, etc.

usage

DatadogMetricTelemetryConsumer has two constructors:

• DatadogMetricTelemetryConsumer(string[] namesOfRelevantMetrics, StatsdConfig statsdConfig) - accepts a collection of metric names to be tracked and datadog statsd configuration

    siloBuilder.ConfigureServices(services =>
    {
      services.AddSingleton(serviceProvider =>
          new DatadogMetricTelemetryConsumer(
              new[] {"App.Requests.Total.Requests.Current"},
              new StatsdConfig
              {
                  StatsdServerName = "127.0.0.1",
                  StatsdPort = 8125
              }));
      services.Configure<TelemetryOptions>(
          telemetryOptions => telemetryOptions.AddConsumer<DatadogMetricTelemetryConsumer>());
    });

  Here, Orleans will detect that DatadogMetricTelemetryConsumer is already registered in the collection of silo's services (the AddSingleton bit) and will not instantiate it again.

• DatadogMetricTelemetryConsumer() - Orleans uses this one by default if DatadogMetricTelemetryConsumer instance cannot be found in the collection of silo's services.

  siloBuilder.ConfigureServices(services =>
  {
      services.Configure<TelemetryOptions>(
          telemetryOptions => telemetryOptions.AddConsumer<DatadogMetricTelemetryConsumer>());
  });

  Here, Orleans will instantiate DatadogMetricTelemetryConsumer using the default constructor.

A fleshed out example can be found in e.g. the road to orleans.
