I got frustrated with Zabbix because as things grew, it became very cumbersome to add services to be monitored, especially in an environment like mine where I need to monitor a lot of Cisco gear, but I don't necessarily want to graph the state of every port. I decided to try OpenNMS because of the "enterprise" level monitoring systems they are the most committed to Open Source (IMHO, "Open Core" doesn't count and I try and avoid it whenever possible). I like it because it does a very good job of discovering your network. I have things set up so that as soon as a new switch sends a SNMP trap OpenNMS will discover the switch and start monitoring it. The discovery process and what gets monitored is highly customizable as well. One other thing that I like is that it uses PostgreSQL as it's database, which probably not everyone would :). One downside of OpenNMS is that it's configured through a large number of XML files. It can be hard to grok what goes where at first and the documentation is sketchy at best. It's also annoying when you install a new version and you have to go through a few .rpmnew files to see what changed (although I bring a lot of that pain on myself since I'm running nightly snapshots of the development version). One other downside is that for large environments you have to do a lot of tuning of PostgreSQL and be prepared to commit a lot of memory. I have my setup running pretty well right now but I had to throw a lot of resources at it. But maybe that's just because I don't have a lot of experience optimizing PostgreSQL databases. Professional support is available for OpenNMS... maybe if Fedora is serious about using it they might comp us some support? I'm really still in the testing phases with it, as I don't have a lot of time to really dig into the details. I'm not sure how long I'll be running it though as non-technical issues might prevail (the rest of the department isn't as committed to Open Source as I am and want something shrink-wrapped and GUI-riffic). -- Jeff Ollie _______________________________________________ infrastructure mailing list infrastructure@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/infrastructure
