I'm a big fan of Zenoss and have been using it in production for over 5 years in various environments and across different releases. Very mature open source project with commercial support options and plugins. People I know that came from OpenNMS prefer Zenoss once they get some time with it, and as opposed to Cacti which is strong at MRTG style graphing and has monitoring only as a plugin afterthought, Zenoss is built for both. http://www.zenoss.com/ Good luck, -Scott -----Original Message----- From: Ben Bartsch [mailto:uwcableguy@gmail.com] Sent: Friday, March 08, 2013 11:38 AM To: NANOG Subject: Intermapper vs NetBrain vs some other for NMS Hi all: I'm looking for information anyone might have comparing Intermapper to NetBrain for NMS. Stuff like devices up/down, interface utilization, building maps for documentation, etc. IMO, Intermapper works great, when it works. Tech support has been slow and often cannot fix the problems, not to mention they release updates about once every other week. Anyone familiar with any similar products? We are presently evaluating NetBrain and it seems really nice. We really like the Visio-like aspect of it. Thanks! -Ben
