That depends on the app doing the configuration, wouldn't you say? I 
myself, having deployed Nagios in about 20 corporate networks of varying 
size find it to be the exact opposite.
Also, the learning curve can be reduced to near nothingness with 
competent coding. This raises the user availability and greatly reduces 
the effort/beneficiary-ratio for the program author (Ethan). After all, 
the greatest program in the world is worthless if noone uses it.

I'm not sure what programs you've used, but we've tweaked the default 
values over a period of two years. All of our customers find them to be 
quite perfect for near enough 100% of their hosts.

But having one or two people familiar with the rather complex syntax and 
relationship scheme of Nagios makes the workload very heavy for those. 
And what happens when the precious few who knows how to configure the 
company network monitoring tool quits their jobs?

A wise suggestion no matter what tool is used for configuration.

For a small network, maybe. For a medium or large (100+ hosts), not a 
chance. When the editor fellows are done entering hostnames, aliases and 
addresses the webconfig crew will have an adequate and working 
configuration up and running.
