The idea behind this project is to learn about Grafana and Prometheus. It can be used as a template too.
- A
docker-composeis used to bundle all the needed components:- PORT
3000→ API written in rust - PORT
3001→ Grafana- usr:
admin - pwd:
admin
- usr:
- PORT
9090→ Prometheus
- PORT
Using make, the containers are started, and the entire setup is initiated.
To test the dashboard, you can open Grafana in your preferred web browser with: http://localhost:3001/login. Login with the credentials (admin/admin), go to the Dashboards section and open the Transactions DEMO dashboard.
The panels will be blank. To populate them with data, we can send some information to the API:
watch -n 1 'curl -s -X POST http://localhost:3000/transact -H "Content-Type: application/json" -d '\''{"operation": "reada", "id": 4, "value": 100.50}'\'We will be sending a POST request every second. The dashboard on the left should always show an increasing value, while the dashboard on the right should reach a value of 1, indicating 1 TPS.
The following image shows a possible output:
The key about this project is the monitoring folder.
grafana_povisioning→ Thedocker-compose.yamlfile mounts this folder- It has configuration files:
dashboard.yamldatasource.yaml- Note: The
datasource.yamlhas auidthat is then used indashboard.json. I've tried to export the dashboard as proposed by the following URL, but it didn't work.
- It has configuration files:
prometheus.yaml→ Scrapping interval and URL to scrap, prometheus scrapes the URL/metrics endpoint.
