Stratara.ServiceDefaults
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
License: MIT.
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_NAMEshareUnknown.logand delete each other's. Set the variable per service.
Outside Development nothing is deleted.

Prerelease dependencies. This package transitively pulls in two prerelease OpenTelemetry instrumentation packages that have no stable release yet:
OpenTelemetry.Instrumentation.EntityFrameworkCore(beta) andRabbitMQ.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 release for hosts on the Orleans execution model. A durable timer now answers its tick while its handler runs, so a
long handler leaves no reminder error in the silo's log, and a timer that fails is logged by the framework with its
owner and purpose. A commit no longer constructs every registered projection to learn which store readers to wake. No
API change, no schema change and no migration.
### Changed
- **A commit no longer constructs every projection.** On the Orleans execution model, every command that committed
facts constructed each registered projection, with its dependencies, only to learn the names of the store readers to
wake. The names are now worked out once per silo, and the wait for a projection, the rebuild and the full replay's
checkpoint reset use the same list. A rebuild of a name that is not registered is refused before any reader is
paused, with the same message as before.
### Fixed
- **A durable timer answers its tick while its handler runs.** On the Orleans execution model, a durable timer's
reminder call stayed open until its handler returned, so a handler longer than the runtime's response timeout made
Orleans log `Could not deliver reminder tick` at Error for every tick it outlasted. The tick is now answered at once
and the handler runs in a call that carries no response timeout. The timer still fires once per due time, a tick
during its handler still does nothing, and a handler stopped with its silo still fires again on the next one.
- **A failing timer is logged.** A durable timer whose handler threw — or whose owner check or unregistration
failed — was visible only as Orleans' reminder error line. It is now logged as `117_137` `TimerFiringFailed` (Error)
with the owner, the purpose and the exception, and the timer fires again after its retry period as before.
