OpenTelemetry

DurableStack integrates with OpenTelemetry by registering its activity source and meter.

Use this when you want traces/metrics to flow into your existing OpenTelemetry pipeline.

What AddDurableStackOpenTelemetry does

• Adds DurableStack tracing source to OpenTelemetry.
• Adds DurableStack metrics meter to OpenTelemetry.
• Leaves exporter selection to your app's OTel setup.

Example

using DurableStack.Hosting.DependencyInjection;

builder.Services.AddDurableStackPostgres(connectionString, options =>
{
    options.WorkerName = $"orders-api-{Environment.MachineName}-{Environment.ProcessId}";
});

builder.Services.AddDurableStackOpenTelemetry();

Integration guidance

• Keep resource attributes (service.name, environment) consistent across services.
• Use traces to correlate run failures with downstream dependency calls.
• Use metrics for alerting on claims, failures, retries, and lease extensions.

Notes

• OpenTelemetry integration is optional.
• It complements event sinks and hosted observability rather than replacing them.
