[TriLUG] Open source software to monitor hundreds of VMs

[Matt Pusateri via TriLUG]

The one think I didn’t like about Zenoss, was that it stores data in an embedded database that’s hard to backup and deal with.  Upgrades were a pain.  Simple UI, but a pain to manage long term.

Also I’d be remiss if I didn’t give you the Monitoring Sucks github page would tracks a bunch of monitoring software. https://github.com/monitoringsucks/


One thing you probably do want is a script that monitors your vm’s and fixes the parent links. This way when vm’s migrate hosts, your network map stays accurate.

Would like to get the “typical” stats (CPU, RAM, HDD, Network, SWAP, etc).  GUI would be nice as well as an API to add new VMs and extract data.
