Just to add another opinion to the pot, I've used zabbix in several large environments, and I like it a lot.  The 
developer team is decently sized, and very responsive to requests and feedback (they operate a commercial 'support' 
model for the platform, so working on the system is literally their day job - as George pointed out, this is often a 
problem).

Zabbix also supports distributed monitoring, which is very handy for scaling or for monitoring multiple locations 
without dealing with VPNS and the like (or if you have places you need to monitor behind NATs!).  Its major weakness at 
the moment is the weak support for SNMP traps (works great in polling mode, though), so you will want a separate simple 
system for catching traps.  In my opinion, that's just fine, because statistics/trending/basic resource alerting/etc 
are best kept separate from things like "OMG one of my powersupplies is dead!!11one".

Also supports IPMI, which is nice if you have IPMI deployed.  :-)
