Logging into Prometheus Dashboard
When you will enter in your prometheus docker container, you will see directory with name prometheus already mounted at root
To enter in docker container
sudo docker exec -it (container-id) /bin/sh
As we can see that, the container is up and running perfectly and we can now check the Prometheus server at http://your_ip:9090/
We have to click on the status and click on the targets to see what all components are in healthy or unhealthy state.Node can be seen UNHEALTHY and verify that node exporter not started.
