Stratara.Diagnostics

License: MIT.

Generic observability primitives shared by all Stratara packages. Use this to emit Activity / Meter instruments under a uniform source name and stable event-ID schema.

Contents

  • ApplicationDiagnosticsActivitySource("Stratara.Application") + Meter("Stratara.Service") + tag-name constants (correlation.id, causation.id, tenant.id, user.id, event.type, request.type, outcome, outbox.kind) + the metric instruments below. These names are part of the public observability contract — renaming them breaks downstream Grafana/Tempo queries.

Metric instruments (ApplicationDiagnostics.Metrics)

Instrument Type Tags
event_source.append.conflicts counter aggregate.type
event_source.events.appended counter event.type, aggregate.type
outbox.published counter outbox.kind (command / event)
command.duration (ms) histogram request.type, outcome
projection.events.processed counter event.type, outcome
projection.bundle.duration (ms) histogram outcome
saga.events.processed counter event.type, outcome
saga.bundle.duration (ms) histogram outcome
saga.inflight up/down counter

Projections and sagas are real-time bus subscribers without a persisted checkpoint, so these report throughput and latency, not consumer lag.

  • LogEvents[LoggerMessage] event-ID ranges per domain (ChangeSet=100_000s, BackgroundTasks=101_000s, EventStore=102_000s, …, Messaging=108_000s, Update=109_000s, Saga=110_000s). Even hundreds = info/debug, _1xx = error.
  • LoggerScopeExtensions.BeginCreateAggregateScope / BeginUpdateAggregateScope — pre-baked logging scopes for the create/update aggregate flows.

Quick reference

using var activity = ApplicationDiagnostics.Activity.Source
    .StartActivity("CreateOrder");
activity?.SetTag(ApplicationDiagnostics.TenantIdTagName, tenantId);

ApplicationDiagnostics.Metrics.EventSourceAppendConflicts.Add(1,
    new("aggregate.type", "Order"));

Showing the top 5 NuGet packages that depend on Stratara.Diagnostics:

Package Downloads
Stratara.Sessions

ASP.NET Core middleware and provider for Stratara's Actor/Subject session model. Reads tenant and user from JWT claims (or X-Tenant-Id / X-Client-Id headers) and populates the ambient ISessionContextProvider for every request.

Stratara.Mediator

In-process mediator with DI-resolved handlers and pipeline behaviors for the Stratara framework. MediatR-style routing via typed wrapper cache, plus an authorizing decorator and a bucket-lock concurrency primitive.

Stratara.Security

Dependency-light key-store and envelope encryption for the Stratara framework. Production IKeyStore implementation (EnvelopeFileKeyStore) with KEK-wrapped, versioned per-scope DEKs (rotation + revoke + crypto-shred), a file-backed master-key provider, and an AES-GCM blob encryptor with purpose-bound associated data. References only Stratara.Abstractions + BCL crypto — no EF Core, RabbitMQ, Redis, or cloud SDKs.

Stratara.Validation

Vendor-neutral request validation for the Stratara framework — a mediator pipeline behavior that runs IValidator<T> implementations before the handler and throws an aggregated StrataraValidationException on failure. No FluentValidation dependency; an optional adapter is shipped separately.

Stratara.Shared

Umbrella package for the Stratara framework — source-generated logger extensions for command flows, domain-event helpers, merge primitives, and the Tier-A/B abstractions surface re-exported as one transitive bundle.

### Fixed

- **Snapshot loads are now scoped to the aggregate type.** The snapshot read previously filtered
 only by stream id, so when two aggregate types shared a stream id, rehydrating one type could
 pick up the other type's (higher-versioned) snapshot and deserialize it into the requested type —
 silently returning an aggregate with default/empty fields. Snapshot reads now match the aggregate
 type (version-independently, so an assembly rev-bump does not invalidate existing snapshots), and
 snapshot writes are grouped per `(stream, aggregate type)` so a stream carrying more than one type
 snapshots each type independently. A snapshot of type X may now only ever rehydrate type X.

### Changed

- **`ISnapshotRepository` gained type-scoped read overloads.** `GetAsync(streamId,
 aggregateTypeName, toVersion, ct)` and `GetLatestVersionOrDefaultAsync(streamId,
 aggregateTypeName, ct)` are the correct lookups; the previous type-less overloads are now
 `[Obsolete]` because they can return a foreign aggregate type's snapshot on a shared stream.
 Custom `ISnapshotRepository` implementers should add the new overloads.
