The metric counter "disk.usage.average" doesn't exist for entity

Hi,

I am unable to get the performance details for a VM as getting the below error

$servers=Get-Content ".\servers.txt"

foreach ($server in $servers)

{

    $vm=Get-VM $server

    if($? -eq $false)

        continue

    }

    $fileName=".\$server.csv"

    $diskusageaverage=Get-Stat -entity $vm -MaxSamples 168 -Start (Get-Date).AddDays(-1) -IntervalMins 60 -stat "disk.usage.average" | ? { $_.instance -eq "" } | select Entity,Timestamp,Value |Sort-Object Timestamp

        if (($diskus -lt $diskusageaverage.count) -and ($cpuusageaverage[$i].Timestamp -eq $diskusageaverage[$diskus].Timestamp))

        {

            Add-Content -Value "$($cpuusageaverage[$i].Entity.Name),$($cpuusageaverage[$i].Timestamp),$($cpuusageaverage[$i].Value),$($memusageaverage[$i].Value),$($diskusageaverage[$diskus].Value),$($netusageaverage[$i].value)" -Path $fileName

            $diskus++

Can you check with Get-StatType if that metric is indeed not present for a specific VM, or for all VMs?

This can also be caused by 1 VM, which perhaps wasn't powered at the $start time, who is missing that metric.

Can you add the -ErrorAction Slinetly continue parameter on the Get-Stat cmdlet.

Why do you do the Get-Stat four time?

You can do that in one call, with multiple metrics.

Also, why add the MaxSamples parameter when you use the Start parameter?

LucD,

I am looking to get the CPU, Mem and Disk Max utilization Reports for a day for specific time like 10:00 AM - 10:00 PM (only during Office hours), need help on this. below is the output from

get-vm abc | get-stattype

cpu.usage.average

cpu.usagemhz.average

cpu.ready.summation

mem.usage.average

mem.swapinRate.average

mem.swapoutRate.average

mem.vmmemctl.average

mem.consumed.average

mem.overhead.average

disk.usage.average

disk.maxTotalLatency.latest

net.usage.average

sys.uptime.latest

disk.used.latest

disk.provisioned.latest

disk.unshared.latest

[LucD]

Try something like this

$sStat = @{

  Stat = 'cpu.usage.average','mem.usage.average','net.usage.average','disk.usage.average'

  Start = (Get-Date -Hour 10 -Minute 0 -Second 0).AddDays(-1)

  Finish = (Get-Date -Hour 10 -Minute 0 -Second 0).AddDays(-1).AddHours(12)

  Instance = ''

  MaxSamples = [int]::MaxValue

  Entity = Get-VM -Name (Get-Content ".\servers.txt")

  ErrorAction = 'SilentlyContinue'

}

Get-Stat @sStat |

Group-Object -Property {$_.Entity.Name} |

ForEach-Object -Process {

   $_.Group | Group-Object -Property Timestamp |

   ForEach-Object -Process {

   New-Object -TypeName PSObject -Property ([ordered]@{

   VM = $_.Group[0].Entity.Name

   Timestamp = $_.Group[0].Timestamp

   CpuAvg = ($_.Group | where{$_.MetricId -eq 'cpu.usage.average'}).Value

   MemAvg = ($_.Group | where{$_.MetricId -eq 'mem.usage.average'}).Value

   DiskAvg = ($_.Group | where{$_.MetricId -eq 'disk.usage.average'}).Value

   NetAvg = ($_.Group | where{$_.MetricId -eq 'net.usage.average'}).Value

   })

   }

} | Export-Csv -Path .\report.csv -NoTypeInformation -UseCulture

Thanks LucD,

This reports shows average, how can I get the maximum details ? when I change from average to maximum, it shows blank (vCenter :Current Statistics Level 1)

[LucD]

The 'maximum' metrics require a higher Statistics Level, namely 4.

As you find out in the PerformanceManager documentation.

You can, as an alternative, take the maximum value of the averages over a period of time.

Don't forget that the Historical Interval 1 (past day) has in any case aggregated the values to 5 minute intervals.
