observability-sandbox
Open Source monitoring, logging and tracing with Prometheus, Loki and Grafana for:
- Host (CPU, memory, storage)
- Database
- Web API
- Front-end
Prerequisites
- Docker
- Bash
Prerequisites (Windows)
In Windows Command Prompt:
net use h: \\wsl$\docker-desktop-data
For the remaining steps use Docker Desktop with WSL2 back-end, and run from Git Bash
sudo mkdir /mnt/docker
sudo mount -t drvfs h: /mnt/docker
Start all services
docker-compose up --build
Use services
- Front-end (our code): http://localhost:8081/
- API (our code): http://localhost:8080/greet?name=Lars
- Grafana (visualization): http://localhost:3000 (auth: lars/lars)
- Prometheus (metric store): http://localhost:9090/graph
- Loki (log store): http://localhost:3100/ready
- Promtail (log collector): http://localhost:9080/
Start services individually
Instead of using docker-compose, each service can be started individually:
(cd loki && ./restart.sh)
(cd promtail && ./restart.sh)
(cd nodejs && ./restart.sh)
(cd prometheus && ./restart.sh)
(cd grafana && ./restart.sh)
(cd cdn && ./restart.sh)
