Monitoring should be: "central" location with GUI/graphs + agents per bunch of servers. Let me chose from dropdown what I want to see.

If I have to deploy this on each machine than it makes no sense. I know SNMP is able to be used like this, but is μMon ?

You can easily put together something that will send UDP packets with stats at regular intervals. I’ve done that a number of times - https://github.com/rcarmo/raspi-cluster/blob/master/tools/se...
