Opsview open source monitoring
I’ve struggled with the lack of decent open source monitoring for quite some time now. Ok. Yes. Nagios. I know.
I need monitoring with a UI that doesn’t make my eyes bleed. Nagios might as well be a daemon with no UI. This is where Opsview is genius. They’ve built a great multi-user configuration and status UI on top of the nagios backend, and they’ve packaged it up for painless install and upgrades.
I love these guys. I don’t need any of their enterprise features, but I’m inclined to send them some money anyway just for doing such a great job.
