Open-Source and Self-Hosted APM Tools for Rails - FastRuby.io

A guide to setting up open-source, self-hosted Application Performance Monitoring (APM) for Rails applications, covering the three pillars of observability: traces, metrics, and logs. It walks through using OpenTelemetry with Jaeger or Zipkin for tracing, Prometheus with yabeda-prometheus for metrics, and Loki for log aggregation, with Grafana or Kibana as unified visualization layers. Also covers simpler alternatives like the rails_performance gem (Redis-backed) and solid_telemetry (SQLite-backed) for smaller apps that don't need a full external stack.
