The winner, Nagios, pretty much destroyed the field, but OpenNMS got more than twice as many votes as the third most popular choice. This wasn’t unexpected, since Nagios is much more of a general purpose monitoring solution, especially within the target audience of Linux Questions. OpenNMS is built for scale, and thus appeals to a smaller set of users.
But still, it was nice that people took the time out to vote. When you work on an open source project, especially a large scale open source project, you tend to be so heads down making improvements that you forget how useful it can be “as is”.
It’s always nice to know that the work you do is appreciated, so thanks to all who voted.
