[colug-432] unix monitoring

[Travis Sidelinger]

Zenoss is another good one.

We were also using SCOM for Linux.  The failed heartbeat messages were in
the thousands daily and completely useless.

We went with Nagios+NRPE+NagiosQL+Nagstamon+Cacti.  Yes, its configuration
management is not automated, but we did our own scripting to automated the
configs to build from our CMDB.  We needed 5 different instances for
separate isolated environments, so using a solution where we were not
charged 5x was important.  Also, it is a fairly lightweight solution.  It's
not perfect, but got it done and onto the next task.
