Elastic Observability & APM
Use the Elastic Stack as a full observability platform for logs, metrics, and traces.
Elastic Observability turns the search stack into a unified logs-metrics-traces platform, all stored in Elasticsearch and explored in Kibana. Elastic APM adds distributed tracing: APM agents (or OpenTelemetry) instrument services, send spans and transactions to an APM Server, and Kibana's APM app renders service maps, latency distributions, and trace waterfalls. Because traces, logs, and metrics share one store, you can pivot from a slow transaction to its logs by shared identifiers.
Extending a library that already indexes every book so it now also files the timing logs and the courier routes — same catalogue, same search desk, three kinds of records that cross-reference.
