Heres a handy piece of Python that will output a few totals of instances running in CloudStack. It’s handy for Nagios monitoring or some Cacti graphing. Figures include:
- VMware instances
- XenServer instances
- Virtual routers
- System VMs
I don’t have any KVM boxes in my lab so I haven’t added that in yet. I’m using authenticationless port 8096 or the API because I’m lazy, so you’ll need that enabled to use this.

Yes I know using CloudMonkey is probably easier but I like my way better
