Monitoring and Observability Stack

This repository contains a Docker Compose setup for a complete monitoring and observability stack using Grafana, Prometheus, Loki, Tempo, and Alloy with OpenTelemetry.

Architecture

Services

1. Grafana

   • Image: grafana/grafana-oss:11.1.1
   • Configuration: Mounted from ./grafana/ to /etc/grafana/
   • Data Storage: Mounted from grafana-storage volume to /var/lib/grafana
   • Exposed Ports: 3000 (Grafana UI)

2. Prometheus

   • Image: prom/prometheus:v2.54.0
   • Configuration: Mounted from ./prometheus/ to /etc/prometheus/
   • Data Storage: Mounted from prometheus-storage volume to /prometheus
   • Exposed Ports: None (can be uncommented in docker-compose.yaml)

3. Loki

   • Image: grafana/loki:3.1.0
   • Configuration: Mounted from ./loki/ to /etc/loki/
   • Data Storage: Mounted from loki-storage volume to /loki
   • Exposed Ports: None (can be uncommented in docker-compose.yaml)

4. Tempo

   • Image: grafana/tempo:2.5.0
   • Configuration: Mounted from ./tempo/tempo.yaml to /etc/tempo.yaml
   • Data Storage: Mounted from tempo-storage volume to /var/tempo
   • Exposed Ports: None (can be uncommented in docker-compose.yaml)

5. Alloy

   • Image: grafana/alloy:latest
   • Configuration: Mounted from ./alloy/config.alloy to /etc/alloy/config.alloy
   • Exposed Ports:
     • 4317 (GRPC)
     • 4318 (HTTP)

Networks

All services are connected to a Docker network named back-tier.

Volumes

• grafana-storage: Persistent storage for Grafana data.
• prometheus-storage: Persistent storage for Prometheus data.
• loki-storage: Persistent storage for Loki data.
• tempo-storage: Persistent storage for Tempo data.

Configuration Files

• Grafana: grafana/grafana.ini
• Prometheus: prometheus/prometheus.yml
• Loki: loki/local-config.yaml
• Tempo: tempo/tempo.yaml
• Alloy: alloy/config.alloy

Usage

To start the stack, run:

docker-compose up -d

To stop the stack, run:

docker-compose down

Exposed Ports

• Grafana: 3000
• Alloy: 4317 (OTEL Grpc), 4318 (OTEL HTTP)

Uncomment the relevant lines in docker-compose.yaml to expose additional ports for Prometheus, Loki, and Tempo if needed.
