This might be more than what you are looking for, but you
may want to have at
Versiera (https://www.versiera.com/).
There is no cost to the hosted service.
Register for an account, download and install a host agent
in Xen. Quick and
easy.
Agent communications are secured with digital certs. You
will be able to get performance
info, and lots of system information down to the process and
communication levels.
May be overkill for what you want. I should disclose I work
for the company, if you
need more info send me an email.
There are lots of other choices out there you may want to
consider including Nagios,
Fiveruns, Spiceworks, Heroix...
