Next, we need to hook up grafana with prometheus. First, go to hostname:3000.
– Login with admin/admin
– Click ‘add datasource’
– Name: prometheus, Type: Prometheus
– Http settings: http://localhost:9090, select Access: ‘proxy’.
– Click ‘save and test’. This should result in ‘success’ and ‘datasource updated.’
Now click on the grafana symbol in the left upper corner, dashboards, import. Enter ‘2747’ at ‘grafana.com dashboard’. This will say ‘Linux memory’, select the prometheus datasource which you just defined, and click import.
