I would disagree; nagios is not limited to small systems... We're  
currently monitoring about 8500 services on 2834 routers with nagios  
quite successfully and have been doing so for nearly a decade now --  
we started with Netsaint. With custom scripts receiving data from our  
inventory management system, Nagios config generation for 99% of the  
hosts is completely automated with only a handful of special cases  
that are hand-modified as needed. Our investment, both in initial/ 
ongoing man-hours, hardware, etc is minimal so our ROI is decent too ;)
