Re: powercli script to capture cpu & mem usage stats of Individual VM

Hi,

thanks for your prompt reply.

I now get the metric for "Past Day"  interval .  i guess it need time to build for "Past Week" ( also in level 2).

Now this command Works :

PS C:\Windows\system32> Get-Stat -Entity (Get-VM my-vm) -Stat mem.active.average -IntervalMins 5 -MaxSamples 3 | where{$_.instance -eq ""}

MetricId                Timestamp                          Value Unit     Instance
--------                ---------                          ----- ----     --------
mem.active.average      24/01/2013 13:45:00                    0 KB              
mem.active.average      24/01/2013 13:40:00               748226 KB              
mem.active.average      24/01/2013 13:35:00               351286 KB    

But, when i"m trying to use the start/finish , i get the mistake,

$today = (Get-Date -Hour 10 -Minute 30 -Second 0)
$now = (Get-Date -Hour 13 -Minute 30 -Second 0)
Get-Stat -Entity (Get-VM my-vm) -Stat mem.active.average -Start $today -Finish $now | where{$_.Instance -eq ""}   

Get-Stat : 24/01/2013 13:53:14    Get-Stat        Object reference not set to an instance of an object.  
At line:3 char:9
+ Get-Stat <<<<  -Entity (Get-VM my-vm) -Stat mem.active.average -Start $today -Finish $now | where{$_.Instance -eq ""}
    + CategoryInfo          : NotSpecified: (:) [Get-Stat], VimException
    + FullyQualifiedErrorId : Core_BaseCmdlet_UnknownError,VMware.VimAutomation.ViCore.Cmdlets.Commands.GetViStats    

please advise.

thanks, Avi
