stats-observer

Overview ¶

Package stats-observer demonstrates how to use stats.ValidationObserver and stats.ReportErrors with codecs directly — without any HTTP or MQTT adapter.

This is the codec-only observability path: implement just stats.ValidationObserver (one method) and call stats.ReportErrors after each codex.Codec.Decode.

Scenario: an application validates its config file on startup. Invalid config fields emit stats.RecordValidationError events that a production observer would route to Prometheus counters, structured logs, or alerting.

Run with: go run ./examples/stats-observer
