Overview ¶
Package monitor is the alerting engine. It watches container state (Docker events), resource usage (polled stats), restart frequency, and log output, evaluates user-defined rules, and dispatches matches to the in-app feed and configured webhooks. It also maintains a stats snapshot for the Prometheus exporter.
