MMP.Herald.Sinks.File
Writes Herald log events to disk. Plain-text mode produces human-readable lines; structured mode produces NDJSON for machine parsing. Optional file rolling for time-based or size-based rotation, with per-pipeline path templating.
Part of Herald — high-performance structured logging for .NET 8, 9, and 10.
Install
dotnet add package MMP.Herald.Sinks.File
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: file (the identifier the Dashboard form and JSON config use to reference this sink).
Capabilities
- Plain-text or NDJSON output via the format toggle
- Time-based rolling (hour / day / week)
- Size-based rolling (maxBytes per file)
- Retention by file count or total size cap
- Path templating with {pipeline}, {date}, {hour} tokens
Limitations
- Local filesystem only (use a remote sink for cloud storage)
- One file per sink instance — fan-out via multiple sink registrations
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 via internal lock around write+flush.

MMP
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).
