Story of Correlation: Integrating Thanos Metrics with Observabi...
summary
Thanos extends Prometheus with horizontal, highly available storage and a Store API used to stitch metrics into a global view; the project reports ~400 contributors and >10k GitHub stars and plans a 1.0 around the next KubeCon. The demo wires Thanos (sidecar + store), Grafana Agent, Jaeger, logs backend and Parka continuous profiling, then runs a tiny correlator service (~100 lines of code) that uses exemplars with trace IDs to link an alert to a trace and a CPU-burning profile; the automation successfully finds and fixes the offending function.
