Using PowerCLI to get the Virtual Disk Latencies

[Poirot]

Hi All,

I am trying to get the Disk read and latencies on certain VMs

I am quite a beginner on PowerCLi apart from writing some utility one liners

I checked this thread

http://communities.vmware.com/thread/304827

But these counters are not working for Me

Can anyone please help ?

[vSphere PowerCLI] D:\Program Files\VMware\Infrastructure\vSphere PowerCLI> $stats += Get-Stat -Entity "USB-SSAPP" -Stat virtualDisk.totalWriteLatency.average
Start  $today1am.AddDays($intStartDay) -Finish  $today4am.AddDays($intEndDay)
[vSphere PowerCLI] D:\Program Files\VMware\Infrastructure\vSphere PowerCLI> $stats

Returns nothing,

I have created all the variables which I am supplying into the command.

Regards,

P

You could start with checking at which statistical level the period you specified is defined in vCenter.

The "latency" metrics need at least level 2.

I assume that "USB-SSAPP" is the name of an ESX(i) host ?

Hi,

Yes, the statistics level I need to check, and it is not set.

I will check it accordingly.

Anyway, we got Veeam which is doing the same thing.

I will try this script out in my LAB.
