See the TestConsoleExporter.cs for an example of how to use the exporter for exporting traces to a collection.

You can configure the ConsoleExporter through Options types properties and environment variables. The Options type setters take precedence over the environment variables.

MetricReaderOptions (metrics)

For metrics, AddConsoleExporter() pairs the exporter with a PeriodicExportingMetricReader. Use MetricReaderOptions to configure temporality and export interval/timeout:

var meterProvider = Sdk.CreateMeterProviderBuilder()
    // rest of config not shown here.
    .AddConsoleExporter((_, metricReaderOptions) =>
    {
        metricReaderOptions.TemporalityPreference = MetricReaderTemporalityPreference.Delta;

        metricReaderOptions.PeriodicExportingMetricReaderOptions.ExportIntervalMilliseconds = 10_000;
        metricReaderOptions.PeriodicExportingMetricReaderOptions.ExportTimeoutMilliseconds = 5_000;
    })
    .Build();

See TestMetrics.cs for a runnable example.

Environment Variables

The following environment variables can be used to override the default values of the PeriodicExportingMetricReaderOptions (following the OpenTelemetry specification).
