A simple go application that makes use of the prometheus go client library. Two metrics are implemented in this app: a counter vector and a gauge.

• main.go - App's entry point -- starts up metrics and HTTP server as go routines.
• /Metrics- Contains implementation of counter and gauge metrics, in addition to HTTP server to expose metrics
• /Server - Contains app's HTTP server and endpoints

Run the following in project root directory to compile and run the main package

• go run main.go
  

This starts up app's HTTP server, making it ready to listen to client requests at http://localhost:8080. Next, HTTP server in metrics package initializes and starts exposing metrics at http://localhost:6060/metrics.

Run the following in project root directory to run prometheus in a docker container

• docker-compose up -d

You should see prometheus UI and scraped metrics at http://localhost:9090
