Building an APM with OpenTelemetry and OpenSource
summary
Shows a working open source APM built by instrumenting a demo "telescope shop" app with auto-instrumentation agents and exporting OTLP to an OpenTelemetry collector that writes metrics to Prometheus, Jaeger, Loki and dashboards in Grafana. Community activity is huge — ~20,000 commits and ~45,000 PRs/issues — vendors are donating agents, and traces, logs and metrics correlate via semantic conventions. Known problems: trace clock skew of minutes–hours, a collector bug breaking exemplars, and metrics conventions still stabilizing; expect usable metrics/logs in about six months.
