Mimir Integration Plan for Observability Stack

Goal

Add Grafana Mimir for metrics storage and complete LGTM stack implementation with "Trace to metrics" support.

Implementation Steps

• Docker Compose - Add mimir service to docker-compose-observability.yml and docker-compose-observability-dev.yml (Image: grafana/mimir:latest, Ports: Dev 9109, Volume for data)

• Mimir Configuration - Create mimir-config.yml (monolithic mode, filesystem storage, configure retention)

• Grafana Alloy - Update alloy-config.river: replace otelcol.exporter.debug.metrics → otelcol.exporter.otlphttp.metrics, endpoint http://mimir:9009/otlp/v1/metrics

• Grafana Data Source - Create grafana/provisioning/datasources/mimir.yml (Type: Prometheus, URL: http://mimir:9009/prometheus) + manually add for external Grafana

• Dashboard - Add RED metrics panels and update validatorinfo-overview-import.json with ${DS_MIMIR}

• Documentation - Update docs/OBSERVABILITY.md with Mimir description and available metrics

• Testing - Verify metrics ingestion locally and trace-to-metrics correlation on production

Expected Result

• ✅ Complete LGTM Stack (Loki + Grafana + Tempo + Mimir)
• ✅ RED metrics from OpenTelemetry
• ✅ Correlation between traces, logs, and metrics
