Hi, Donald. We have used Big Brother happily for years: http://bb4.com/.  
BB is terrific, but I think Nagios (http://www.nagios.org/) is probably
the contemporary gold standard. I'd probably use Nagios if I were
implementing something from scratch now, and weren't already settled into
a ~8 year old BB system.
