The Holy Trinity of Observability: Logs, Metrics, and Traces
summary
Live demo shows a concrete pipeline for monitoring Spring Boot microservices using the Elastic Stack: system metrics from metricbeat, network captures from packetbeat, structured logs via filebeat modules, uptime with heartbeat, filesystem events with auditbeat, and distributed traces stored from Sleuth into Zipkin. Three nodes collect ~1,200 requests in 15 minutes with 99th percentile latency ~3s, an injected bad-jar causes OOMs, stack-hash grouping surfaces the top error (32 occurrences), and killing the frontend produces immediate 502 and heartbeat alerts.
