The Ultimate Self-Hosted Observability Stack: Prometheus + Grafana + Loki + Uptime Kuma
Vendor lock-in on APM and monitoring platforms like Datadog, New Relic, and Dynatrace is notorious for unpredictable billing spikes. Adding custom tags, ingestion volume, or retained log indices can quickly turn a $200/mo budget into a $2,000/mo surprise invoice.
With this open-source Docker Compose observability pipeline, you get:
System Metrics & Dashboards: Prometheus + Node Exporter + cAdvisor visualized in Grafana.
Structured Log Aggregation: Promtail shipping container logs to Loki without heavy ElasticSearch overhead.
