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 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.
