Hello

I would like to monitor my openstack deployment like get statistical data from NICs, hard drive usage, when a service goes down, when a vm gets created or deleted, statistical data from vms like network usage, hard drive usage, cpu usage. I have seen online that tools like Cacti and Nagios can do that but from my searches I could not find any information on how to do that. If someone that has done that before could point me in the right direction it would be awesome.

Thank you
