Re: Disk Performance/Latency Check - ESXi 5.1

The basic structure is to use the Get-Stat cmdlet and use the Group-Object to split up the results.

Something like this

$start= (Get-Date).AddDays(-2)$counters="disk.commandsAborted.summation","disk.totalLatency.average","disk.queueLatency.average"
$entity=Get-VMHost-NameMyEsx
Get-Stat-Entity$entity-Stat$counters-Start$start|Group-Object-PropertyTimestamp|%{  New-ObjectPSObject-Property@{    Name=$_.Group[0].Entity.Name
    Time=$_.Group[0].Timestamp
    CommandsAborted=$_.Group|where {$_.MetricId-eq"disk.commandsAborted.summation"} |Select-ExpandPropertyValue
    TotalLatency=$_.Group|where {$_.MetricId-eq"disk.totalLatency.average"} |Select-ExpandPropertyValue
    QueueLatency=$_.Group|where {$_.MetricId-eq"disk.queueLatency.average"} |Select-ExpandPropertyValue
  }
}

You can of course do this for multiple ESXi servers or take an average over the complete timespan.
