netdata - live server metrics
If your looking for a really good opensource realtime resource monitoring tool check out netdata.io
Very light, looks great and is super fast. I have it running as a docker instance on my unraid server (which runs this website, and a couple of other docker instances).
If you want to show extra info about containers / docker running on your host add the following host mappings;
container <- host
/var/run/docker.sock <– /var/run/docker.sock /host/proc <– /proc /host/sys <– sys
