I've used OpenNMS for many years. In a word, it is fantastic. You'll need to do some reading and prep work, but that is true for any NMS solution you bring on-line. The docs for OpenNMS are *very* good. The step-by-step for the install is detailed and comprehensive. What I love most about OpenNMS is that you can truly craft it to match your exact needs. The only caveat is that you need to get a big enough box (or series of boxes) to do all the monitoring/scanning that you want. The bigger your network, the more processors you are going to need. Right now I monitor about 800 routers, switches, and gateways using a box with an AMD Athlon(tm) XP 2800. My monitoring cycles range from 2 to 5 minutes. If I wanted to drop that cycle to once a minute on all devices, I would have to buy a second box and split the tasks. Also, if you want to store lots of historical data (and honestly, who doesn't want to do that!) then you'll need some large capacity hard-drives on the box. OpenNMS does some nice things to pare down the size of the historical data, but with 800+ devices all storing three hundred to a thousand data points every day, things build up! We also have a SolarWinds install (a windows based NMS app), and in my somewhat biased opinion, OpenNMS beats it hands down. OpenNMS is far more configurable - yet easier to setup, monitors a hell of a lot more device with shorter times between cycles, and has NO licensing!
