Structured logs Include correlation IDs to link logs to traces. log.LogInformation("{CorrelationId} handling {Message}", id, msg); Metrics to watch Mailbox depth per actor Message processing latency Restart counts and deadletters Sample dashboard graph LR subgraph Metrics m1[Mailbox depth] m2[Processing latency] end subgraph Logs l1[Correlation ID] end subgraph Traces t1[Spans per PID] end m1-->l1 m2-->t1 Start with these building blocks and iterate: good observability turns incidents into quick fixes rather than mysteries.
