Herald.Sinks.Slack

Sends Herald log events to a Slack webhook URL as formatted messages with per-level emoji. Intended for high-severity alerts — stack behind a Warn-or-above filter so routine info events don't swamp the channel.

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

Install

dotnet add package Herald.Sinks.Slack

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

Capabilities

  • Per-level emoji mapping (trace → 🔍, warn → ⚠️, etc.)
  • Slack-markup-safe message escaping
  • JSON-injection-safe body construction
  • Single-event POST (one message per event)

Limitations

  • No batching — one message per event
  • Channel and emoji table configurable only at construction
  • Slack truncates long messages; caller should pair with a message truncation decorator for noisy templates

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.

Vendor

Slack — https://api.slack.com/messaging/webhooks

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).
