Vladimir,

A while back the best cluster monitoring tool was Ganglia (
http://ganglia.sourceforge.net/), but it has not been maintained for
several years. There are quite a few alternatives out there, I found
nightingale (https://github.com/didi/nightingale) to be simple to install
and use.
Good luck,
  George.
