Anybody know where I can find Visio stencils for Netgear products

Wikipedia has a comparative table which helps a lot

I think the key differences are:

• language: Nagios is written in C and OpenNMS in Java. It makes nagios a lot faster on older hardware.

• Data collection: Nagios performs very little data collection. Other software (like cacti for example) will be required for a more extensive data collection system. OpenNMS includes it out of the box.

• host and service discovery: Nagios has to be told what to monitor whereas OpenNMS has discovery features.

There is one think in the "smart managed" product description that has me recoiling in horror and considering it "not suited for purpose" and that is the phrase "web console".

Without a mention of a telnet/ssh-based admin interface, there is no sensible way of driving the switch from code and that's a want-have for an SMB (and a must-have for a large company). A pohysical console is also a must-have.

Of course, the "fully managed" doesn't say one way or another, so I can't really get behind that either.

I think, at the end of the day, the thing to do is to purchase one of each (or, ask a suitable local vendor if you can have a loaner of each for a couple of weeks), evaluate them and see which one meets your needs and wants. Once you have that, you can then decide if the trade-off between functionality and price speaks to the cheaper or the more feature-full switch.
