Cross-host observability defaults for the Stratara stack. Reference from every host (API, worker) to get OpenTelemetry + Serilog wired up with sensible defaults.

What's in the box

Extension Purpose
ConfigureOpenTelemetry Logging + metrics + tracing with HTTP, EF Core, RabbitMQ, runtime instrumentation; OTLP exporter wired up automatically when OTEL_EXPORTER_OTLP_ENDPOINT is set. Accepts optional MeterProviderBuilder / TracerProviderBuilder callbacks for host-specific extras.
ConfigureSerilog Structured logging with destructuring attributes, async console sink, OTLP sink (gRPC or HTTP/Protobuf based on OTEL_EXPORTER_OTLP_PROTOCOL), dev-mode log cleanup at {Path.GetTempPath()}/stratara-logs/{service-name}.log — the OS temp directory, so not literally /tmp on Windows or macOS.
ConfigureSerilogBootstrapLogger Sets up Log.Logger as a bootstrap logger before the host is built, so early-startup errors surface to the console.

Quick start

builder.ConfigureOpenTelemetry();
builder.ConfigureSerilog();

It deletes your development log file on start-up

In the Development environment only, configuring Serilog deletes the current log file before opening it: %TEMP%/stratara-logs/{OTEL_SERVICE_NAME}.log, where the service name falls back to Unknown when OTEL_SERVICE_NAME is unset. The intent is a clean file per debugging session rather than one that grows across dozens of restarts.

Two consequences worth knowing before they cost you an hour:

  • A crash you wanted to read is gone the moment you restart to reproduce it. Copy the file before restarting, or point the sink elsewhere for that session.
  • Two development services with no OTEL_SERVICE_NAME share Unknown.log and delete each other's. Set the variable per service.

Outside Development nothing is deleted.

Sibling packages

  • Stratara.EventSourcing.WorkerDefaults — one-stop AddBackendServices / AddXxxWorkerServices composites that wire the framework's mediator + outbox + projections + sagas stack.
  • Stratara.ServiceDefaults.AspNetCore — ASP.NET-specific extras: AddDefaultHealthChecks + MapDefaultEndpoints (/health, /alive) and ASP.NET request OTel instrumentation.

Dependencies

  • Stratara.Shared — diagnostics base (ApplicationDiagnostics.Activity.SourceName).
  • OpenTelemetry runtime + exporter packages.
  • Serilog sinks (Console, File, Async, OpenTelemetry).
  • Destructurama.Attributed for destructuring conventions.
  • Microsoft.Extensions.Http.Resilience + Microsoft.Extensions.ServiceDiscovery.

Prerelease dependencies. This package transitively pulls in two prerelease OpenTelemetry instrumentation packages that have no stable release yet: OpenTelemetry.Instrumentation.EntityFrameworkCore (beta) and RabbitMQ.Client.OpenTelemetry (RC). Both ride the stable OpenTelemetry 1.15.x core. NU5104 is suppressed in this csproj with that justification — consumers inherit the prerelease deps transitively. We will swap to GA as soon as the vendors ship stable.

A fix for hosts on the Orleans execution model. A store reader that catches up a large backlog and a singleton
work that runs long now answer their keep-alive, so neither leaves reminder errors in the silo's log. A silo that
joins while a singleton work runs long on another silo no longer fails its start. No API change, no schema change
and no migration.

### Fixed

- **A busy store reader or singleton work answers its keep-alive.** On the Orleans execution model, a projection or
 saga reader that caught up a backlog for longer than the runtime's response timeout made its keep-alive tick wait
 behind the catch-up, and Orleans logged `Could not deliver reminder tick` at Error, once per partition and
 keep-alive period. A singleton work whose run outlasted the timeout did the same. Nothing was lost, but a large
 catch-up left dozens of errors on the silo. The keep-alive and the poll now start a catch-up where none is
 running and do not wait for it. A partition is still read by one catch-up at a time, and a commit during a
 catch-up is still applied by it. A singleton work's keep-alive interleaves with its run, and runs still never
 overlap.
- **A silo starts while a singleton work runs long.** A silo that started while a singleton work it registers ran
 longer than the response timeout on another silo waited for that run in its own start. The start then failed
 with a `TimeoutException`. The call a starting silo makes to each singleton work and store reader now
 interleaves, so the start goes on.
- *Operate the Orleans execution model* says that a durable timer whose handler outlasts the response timeout
 still makes Orleans log `Could not deliver reminder tick` for that tick, and that the line says nothing about
 the timer. It also says that, outside a deploy, the line now points to an unreachable store reader or singleton
 work rather than a busy one.
