Using Get-EsxTop to get NetWorld CPU

[nicholas1982]

Hi All,

Currently I use ESXTOP via ssh and use the expand function using the GID of a VM the get the individual worlds that make up a VM, I'm interested is capturing the %USED CPU of the 4 NetWorld processed as this VM has 4 NICs

I'd like to know if I could use Get-EsxTop to capture CPU %USED on the NetWorld of a VM?

Yes, you can, although it is not too obvious.
See for example my Hitchhiker’s Guide To Get-EsxTop – Part 1 post.

Thanks Luc,

So I'm making some progress I just need to figure out how to get the world for the NetWorld.. In addition I needed to change a bit of the code to get the VMXCartelID by replacing $esxcli.vms.vm.list() with $esxcli.vm.process.list() I'm on 6.7 perhaps its changed

Would you be able to help with getting the NetWorld ?

$vmName = "MyVMName"

$esxcli = Get-EsxCli

$vmxid = $esxcli.vm.process.list() | where {$_.DisplayName -eq $vmName} | Select VMXCartelID

$esxtopInterval = 5

$conversion = 100 / (1e6 * $esxtopInterval)

$first = $true

$report = @()

for ($i = 0; $i -lt 10; $i++) {

   $stats = Get-EsxTop -CounterName VCPU | where {$_.VCPUID -eq $vmxid.VMXCartelID}

   if (!$first) {

   $row = "" | Select VCPUID, WorldName, Run, Ready

   $row.VCPUID = $stats.VCPUID

   $row.WorldName = $stats.WorldName

   $row.run = "{0:p1}" -f (($stats.RunTimeInUsec - $run) * $conversion)

   $row.ready = "{0:p1}" -f (($stats.ReadyTimeInUsec - $ready) * $conversion)

   $report += $row

  }

   else {

   $first = $false

  }

   $run = $stats.RunTimeInUsec

   $ready = $stats.ReadyTimeInUsec

  sleep $esxtopInterval

}

$report | ft -AutoSize

Not sure I get what you mean by "Networld"?

[nicholas1982]

Hi Luc,

You know with ESXTOP you can hit 'e' to expand all the worlds that make up the VM, if you see attached screenshot there is one world here called 'NetWorld-VM-209' I want the %USED cpu for that world if possible?

[LucD]

Ok, got it, these are Tx threads for VM-to-VM communication.
Let me check.

[nicholas1982]

Hey Luc,

Exactly, I should have mentioned they were Tx threads. anyway if I manually specify the ID as per the screenshot I think it works but of course I need a way getting this ID

[LucD]

Try the following.
I used a -contains operator since a VM can have more than 1 Tx thread.

$vmName = "MyVM"

$vm = Get-VM -Name $vmName

$esxcli = Get-EsxCli -VMHost $vm.VMHost -V2

$vmxid = $esxcli.vm.process.list.Invoke() | where {$_.DisplayName -eq $vmName} | Select VMXCartelID

$group = (Get-EsxTop -TopologyInfo -Topology SchedGroup).Entries |

   where {$_.GroupName -match "vm.$($vmxid.VMXCartelID)"}

$networldId = $group.CPUClient | where {$_.VCPUName -match "^Networld-"} | Select -ExpandProperty CPUClientID

$esxtopInterval = 5

$conversion = 100 / (1e6 * $esxtopInterval)

$first = $true

$report = @()

for ($i = 0; $i -lt 10; $i++) {

   $stats = Get-EsxTop -CounterName VCPU | where {$networldId -contains $_.VCPUID}

   if (!$first) {

   $row = "" | Select VCPUID, WorldName, Run, Ready

   $row.VCPUID = $stats.VCPUID

   $row.WorldName = $stats.WorldName

   $row.run = "{0:p1}" -f (($stats.RunTimeInUsec - $run) * $conversion)

   $row.ready = "{0:p1}" -f (($stats.ReadyTimeInUsec - $ready) * $conversion)

   $report += $row

   }

   else {

   $first = $false

   }

   $run = $stats.RunTimeInUsec

   $ready = $stats.ReadyTimeInUsec

  sleep $esxtopInterval

}

Hi Luc,

Seems to work well, just wondering though what would I need to do to get %USED rather than %RUN ?

[LucD]

Try like this.
The mappings between the properties and the columns in esxtop can be found in my Hitchhiker’s Guide To Get-EsxTop – Part 2 – The Wrapper post.

Note that the list is not an official document, something that a previous PowerCLI PM seems to have left laying around :smileygrin:

$vmName = "MyVM"

$vm = Get-VM -Name $vmName

$esxcli = Get-EsxCli -VMHost $vm.VMHost -V2

$vmxid = $esxcli.vm.process.list.Invoke() | where {$_.DisplayName -eq $vmName} | Select VMXCartelID

$group = (Get-EsxTop -TopologyInfo -Topology SchedGroup).Entries |

   where {$_.GroupName -match "vm.$($vmxid.VMXCartelID)"}

$networldId = $group.CPUClient | where {$_.VCPUName -match "^Networld-"} | Select -ExpandProperty CPUClientID

$esxtopInterval = 5

$conversion = 100 / (1e6 * $esxtopInterval)

$first = $true

$report = @()

for ($i = 0; $i -lt 3; $i++) {

   $stats = Get-EsxTop -CounterName VCPU | where {$networldId -contains $_.VCPUID}

   if (!$first) {

   $row = "" | Select VCPUID, WorldName, Run, Ready, '%USED'

   $row.VCPUID = $stats.VCPUID

   $row.WorldName = $stats.WorldName

   $row.run = "{0:p1}" -f (($stats.RunTimeInUsec - $run) * $conversion)

   $row.ready = "{0:p1}" -f (($stats.ReadyTimeInUsec - $ready) * $conversion)

   $row.'%USED' = "{0:p1}" -f (($stats.UsedTimeInUsec - $used) * $conversion)

   $report += $row

   }

   else {

   $first = $false

   }

   $run = $stats.RunTimeInUsec

   $ready = $stats.ReadyTimeInUsec

   $used = $stats.UsedTimeInUsec

  sleep $esxtopInterval
