Herald.Sinks.AwsCloudWatch

Writes Herald log events to an AWS CloudWatch Logs log group / log stream via PutLogEvents. Drop-in for Serilog.Sinks.AwsCloudWatch. Honours CloudWatch's 10,000-event / 1 MB batch ceiling and the 256 KB single-event ceiling. Optional auto-create of log group and stream.

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

Install

dotnet add package Herald.Sinks.AwsCloudWatch

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

Capabilities

  • Single and batched PutLogEvents (respects 10,000-event / 1 MB / 256 KB ceilings)
  • Stable-sort by timestamp to satisfy CloudWatch's chronological-order requirement
  • JSON-formatted message bodies for CloudWatch Logs Insights queries
  • Default AWS credential chain (env, shared creds, IMDS, SSO, role)
  • Code-first overload accepts a pre-built IAmazonCloudWatchLogs client

Limitations

  • No retention-policy management — configure via IaC or installer
  • Oversize events truncate silently rather than fail the batch
  • Synchronous Send path (.GetAwaiter().GetResult() around async AWS SDK calls)

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 — the AWS SDK client is thread-safe per AWS SDK contract.

Vendor

Amazon Web Services — https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/

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).
