We use and seriously appreciate OpenNMS. So, OpenNMS is helping to end world poverty by keeping Mifos infrastructure up and running!
Once OpenNMS was installed, I forgot about it, until it thankfully told me about a server that went down! Maintenance costs are minimal, and it's easy to get help with OpenNMS from their plentiful and useful community resources. It's one of the most reliable systems we use. Once it's on, it just works. I like that OpenNMS makes my job easier. Thank you!
