# Example Go app that exposes Prometheus metrics
[](https://goreportcard.com/report/github.com/kostis-codefresh/prometheus-sample-app)
Original code modified from https://gabrieltanner.org/blog/collecting-prometheus-metrics-in-golang
## How to build
Run:
* `go build` to get the executable OR
* `docker build . -t example-app` to create a container image if you prefer docker instead or don't have access to a Go dev environment
## How to run the application on its own
* `go run .` OR
* `docker run -p 8080:8080 example-app`
Then visit http://localhost:8080 or http://localhost:8080/metrics
## How to run with Prometheus and Graphana
Run `docker-compose up`
You can access Prometheus at http://localhost:9090 and Graphana at http://localhost:3000
1. Login into Graphana. Default user/password for Graphana is admin/admin
1. Add a datasource for type Prometheus at address http://localhost:9090 and auth type "Browser"
1. Import [graphana/graphana-dashboard.json](graphana/graphana-dashboard.json) as a premade dashboard
