Question about Nagios Features

[Mike Lindsey]

Short answer:  Yes.

Medium answer: The free version can provide all of this, but it takes 
some work to get what you want.  The paid version will give you a lot 
more of this right out of the door.

Long answer: Go to nagios.org, read the docs, play with the demo, 
download the software.  Install it somewhere, play with it for a day.  
Then go hit Nagios Exchange and download some addons that fix whatever 
you think doesn't work quite the way you want.  It sounds like you're 
going to be monitoring a complex environment.  That means that your 
monitoring environment is going to be complex as well - at my work we 
monitor over a hundred discrete host profiles on a vast (though still 
incredibly small in comparison to some other installations) with some 
shared monitoring, but a lot of unique custom monitoring that performs 
deep application health checks on custom apps.

You get what you put out.  In a large environment you can put out half a 
million dollars a year in licensing and support, and potentially 
millions in professional services dollars, getting something that you 
might not understand - tying you and your business to an external org 
through a hefty financial leash.  Alternately, you can download some 
free software (or pay an entirely reasonable sum for a better version 
and professional support) and put some effort into learning the tool, 
resulting in a monitoring environment that does everything you want it 
to, that you understand in and out, and hopefully the adoration of 
management -and- your operations teams.
