For those who don't know, Netdata is a kind of "agent" that gather metrics and expose a nice dashboard in live. See a live demo here: http://95.216.43.14:19999
We asked Netdata devs to add Xen related metrics, and guess what, they did it!
It's still in a dev branch right now, but you can see the Xen related chart in the first link given.
What's great with Netdata is the fact you can "stream" to a central Netdata host ("push data" model, no need to declare anything in your central monitoring host) and also connect this central node to a Prometheus/Grafana to get long term metrics.
For those who want to test right now with Xen metrics:
This is NOT recommended in production until we got a binary package, this could BREAK your host
yum install yajl-devel xen-dom0-libs-devel libuuid-devel zlib-devel zlib automake autoconf git make gcc --enablerepo='base'
git clone --branch xenstat https://github.com/vlvkobal/netdata.git
cd netdata
./netdata-installer.sh
