Now that you have the full stack running, it's time to setup grafana. The first thing we need to do is login to the UI and update the default password. The credentials are set as user: admin pass: admin
Next, lets add the prometheus data source to grafana for metric query. Click the configuration cog wheel in the left nav window.
Then select data sources and add data source.
Select the Prometheus data source on the next page and add the URL to point to your prometheus host.
Test and save the data source configuration and click the back button
Thats it, you're ready to query metrics in grafana from prometheus!
