Instrumenting Go applications using Prometheus and Grafana - Demo

Instrumenting a Go application

Tools used ⚙️

• Prometheus: for recording/scraping metrics from the application
• Grafana: for visualizing the obtained metrics from the prometheus server

To run the application ⚡️

NOTE: Docker and Docker compose are required.

1. Run the services (app, prometheus, grafana) using docker-compose - docker-compose.yml

$ docker-compose up --build 

2. View the scraped metrics at http://localhost:5000/metrics
3. Hit the quote endpoint at http://localhost:5000/quote to record the api_latency_seconds metric for that path.
4. Query the metrics on the prometheus server at http://localhost:9090
5. Visualize the metrics on grafana at http://localhost:3000

Grafana authentication details are available at /grafana/grafana.ini

Voila! 🎉

Create your dashboard on Grafana, add the desired datasource (prometheus server), and PromQL queries to visualize the metrics.
