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 host that removed or renamed a projection no longer has that
projection's store readers come back on every start and fail each entry; they retire once, as a saga's readers do. A
retired store reader now logs its retirement once instead of three times, and leaves no reminder error behind. No
API change, no schema change and no migration.

### Fixed

- **A reader of a removed projection retires.** On the Orleans execution model, a host that removed or renamed a
 projection kept the keep-alive reminders of its store readers. On every start of the silo they brought the readers
 back, and each one read the next entry of its partition, failed it because no projection of its name was
 registered, and tried again on the next tick, without end — a warning per partition and entry. Such a reader now
 retires the first time it is brought back, as a saga's reader already did: it unregisters its keep-alive, logs
 `117_136` `UnregisteredProjectionReaderRetired` (Information) once, reads nothing and deactivates. Its checkpoints
 stay, so a projection registered again resumes where it stopped; *Operate the Orleans execution model* says how to
 delete them. In a rolling deployment that adds a projection, a reader that lands on a silo of the earlier version
 refuses a rebuild's or a replay's pause, which then fails naming it, and a wait counts its partition as behind.
- **A retired store reader logs its retirement once.** A reader that retired as it was activated — of a partition
 beyond a lowered partition count, or of a saga the silo no longer registers — deactivated before it answered the
 call that activated it. Orleans forwarded that call to a new activation, which retired again, so the retirement was
 logged three times per reader and the keep-alive tick ended in `Could not deliver reminder tick` at Error. The
 reader now answers the call first and deactivates after it.
