Herald.Sinks.Loki

Posts Herald log events to Grafana Loki's push endpoint. Groups events into streams by label set so batches produce the minimum number of Loki streams, and keeps high-cardinality properties out of the label index so an operator misstep cannot explode it.

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

Install

dotnet add package Herald.Sinks.Loki

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

Capabilities

  • Batched delivery via IBatchedLogSink
  • Streams grouped by label set — fewer streams per batch
  • Nanosecond-precision timestamps (string to avoid JS i53 loss)
  • Cardinality guard — properties never promoted to labels
  • Auth: bearer token OR basic-auth credentials (mutually exclusive)
  • Label-name sanitisation (operator typos land with underscores rather than 400s)

Limitations

  • Static labels + basic-auth supplied at construction only
  • Synchronous Send path; pair with async decorator for throughput
  • No compression on the request body

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 — shared HttpClient, synchronous Send.

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).

Package Downloads
MMP.Herald.Business

Herald observability metapackage for business and enterprise deployments. Pulls in every Herald.Sinks destination — HTTP, TCP, UDP, every Enterprise HTTP sink (Seq, Splunk, Honeycomb, Datadog, Loki, SignalFx, Sentry, PagerDuty), community transports (Elasticsearch, Slack, GenericWebhook), and the OTLP trio. Depend on this one package and pick destinations at registration time.
MMP.Herald.Game.Pro

Herald observability metapackage tuned for paid-tier games. Pulls in the network transports (HttpJson / TcpJsonLine / UdpJsonLine), the Enterprise HTTP observability sinks (Seq, Splunk, Honeycomb, Datadog, Loki, SignalFx), Sentry for crash tracking, the generic-webhook sink, and the OTLP trio. PagerDuty, Elasticsearch, and Slack are deliberately excluded — those are business/on-call surfaces rather than game-side.
