I currently have a deployment of over 50 hosts in a VMware datacenter. I can get performance statistics on a per-host basis, but I was wondering if there is a way to get a consolidated view of statistics for some performance statistics added together to assist in scaling my environment.
For example:
Each one of the 50 Hosts have their own local datastores and perform a certain amount of IOPs in a given time. I would like to know how many IOPs my entire datacenter produces so that we can determine if a SAN would be an option for our environment or if the IO requirement is too high.
Any suggestions, ideas, scripts or utilities are acceptable.
I'm running 5.1u1 on all of the hosts
Thanks
