This is a demo Go app that shows how you can collect system metrics. The metrics can be viewed via a UI or simple API.

1. Clone this repo
2. Run make build

To run the app start the container with:

docker run -p 8080:8080 eye-of-sauron

By default the application will report on container stats. To get host stats start the app with the following:

docker run -p 8080:8080 -v /proc:/host/proc:ro -e HOST_PROC=/host/proc eye-of-sauron 

Once the application is running you can access the UI at http://localhost:8080/

The API docs can be accessed at http://localhost:8080/swagger/index.html

You can change the frequency metrics are collected by editing eye-of-sauron.yml.

You will need to rebuild after config changes.
