How can i sort VM's by high i/o in vSphere ?

[mjw123]

Hi,

I have an ESXi cluster  running several hundred VM's - i'm keen to establish which VM's are generating the highest level of storage i/o

Is this possible through vSphere - so they can be ranked to see say the top 20 busiest VM's ?

This could be done manually by looking at performance data for each but obviously a huge task.

tia,

This is something we've struggled with also.  My company is looking at Veeam One to be able to report on things like this.

you can also get this information through esxtop, although only real-time

[JagadeeshDev]

If you have powerCli , try this

Conenct to VI-Server

Get-VM | Select-Object Name, NumCPU, MemoryMB, ProvisionedSpaceGB | Export-Csv

This will give you name of VM, and the utilization .

Cheers !

Any further thoughts on this - i've tried batch capture in esxtop but the output is difficult to get meaningful information from.

The free vCenter Operations Manager(Foundation) can provide some great insight to Disk IO and problematic VMs and doesn't take too long to implement. Also the analytics available with the paid versions provide exactly what you are looking for.
