Les,
Compared to Nagios, how difficult was it to get OpenNMS running in your
environment? I found Nagios trivial but have never really rolled my sleeves
up with OpenNMS, I have just sort of kicked the tires over the years...

I have to say the WMI capability of Zenoss is a real plus for me and the
documentation  for Zenoss looks way better than OpenNMS which even they
admit on the wiki isn't very good:)
