Metrics

Metrics

DotPulsar support metrics from version 2.3.0 following the guidelines from the OpenTelemetry project.

Enabling metrics

All that's needed for metrics to work is to add the 'DotPulsar' meter to OpenTelemetry's MeterProviderBuilder.

.ConfigureServices(services =>
{
    services.AddOpenTelemetryMetrics(builder =>
	{
	    builder.AddMeter("DotPulsar");
	});
})

For more in-depth information about OpenTelemetry for .NET you can read the getting started section and browse the git repository.
