I don't think you provided enough information for anyone to help.
What kind of remote gui are you using?   If it is a full remote X
desktop session (freenx/x2go or native network) you could run anything
you could run locally at the console because it is in fact running on
the server side.  If you are running X locally on the display machine,
you can still run anything you want on the server machine with its
window open on the display desktop.

I think it makes sense because there are already frameworks that are
relatively easy to install and set up even if you initially only
target one host and test - and you can get things like CPU and network
bandwidth tracking for free.   Then if you want, you can expand the
monitoring to other things you are likely to need, but even if you
don't it is probably easier than building your own notification
system.    It's probably not the easiest thing to start with, but
OpenNMS is pretty flexible.  For example if you have an xmpp system
with clients for instant messaging, it can send alerts to a group
conference so the interested people see it without cluttering email.
