Herald.Sinks.OtlpGrpc

Exports Herald log events to an OpenTelemetry collector over OTLP/gRPC. Calls opentelemetry.proto.collector.logs.v1.LogsService/Export with the standard ExportLogsServiceRequest payload. Reuses the hand-rolled protobuf writer from Herald.Sinks.Otlp so payload shape stays identical across HTTP and gRPC transports — no proto codegen, no generated message types.

Part of Herald — high-performance structured logging for .NET 8, 9, and 10.

Install

dotnet add package Herald.Sinks.OtlpGrpc

The sink auto-registers into LogSinkProviderRegistry.Default via a [ModuleInitializer] on assembly load. No manual RegisterAll(...) or With*SinkProviders() call is required — dotnet add package is the whole workflow.

Sink kind: otlp_grpc (the identifier the Dashboard form and JSON config use to reference this sink).

Capabilities

  • OTLP/gRPC log export to any compliant collector (OpenTelemetry Collector, Tempo, Honeycomb, Grafana Agent, etc.)
  • Reuses OtlpProtobufLogSerializer from Herald.Sinks.Otlp — identical wire payload to the HTTP-OTLP sibling sink
  • Raw byte marshallers on the gRPC method descriptor — no proto-codegen step, no generated IMessage types, AOT-clean
  • Batched delivery via IBatchedLogSink
  • Configurable per-call deadline (default 30s)

Limitations

  • No compression on the request body (matches the HTTP-OTLP sibling)
  • No mTLS / custom credentials configurable through runtime-definition today — construct OtlpGrpcLogSink directly with a configured GrpcChannel for advanced auth scenarios
  • Resource attributes configurable at construction only

Tier & runtime

  • Edition: Community — works on the free Apache 2.0 Herald.Core. No license key required.
  • AOT-compatible: yes
  • Targets: .NET 8 / 9 / 10
  • Thread safety: Thread-safe — GrpcChannel is shared across calls and is itself thread-safe per gRPC contract.

Vendor

OpenTelemetry — https://opentelemetry.io/docs/specs/otlp/

Configuration

Per-sink config form lives in configuration*.mmpform at the package root and inside the assembly as an embedded resource. The Herald Dashboard renders it at runtime; JSON config follows the same shape. See CAPABILITY.yaml shipped at the package root for the full manifest (schema reference: CAPABILITY-SCHEMA.md).
