Collecting performance data from a free ESXi host

[MariusRoma]

I need to create e PowerCLI script to collect performance information (PCU, RAM, ...) about a (free) ESXi host and the guest VMs.

Is there any sample I can start from?

An ESXi node keeps all Realtime performance data for +/- 1 hour.

You should be able to retrieve those via the regular Get-Stat cmdlet.

For example

Get-Stat -Entity $esx -Stat 'cpu.usage.average' -Realtime -MaxSamples 10

Thabnk you very muck.

Let me ask another question: how can I connect to my (free) ESXi host?

Can I use something like:

$myfreeesxi = connect-viserver 192.1.68.1.1 -user "Root"

Is it correct?

Let me try to put everything together:

I wrote the following script:

Add-PSSsnapin VMware.VimAutomation.Core

$myesxi = Connect-Viserver 192.168.1.1 -user root

$cpu = Get-Stat -entity $myesxi -Stat 'cpu.usage.average' - Realtime -maxsamples 1

but there is something wrong with the -entity parameter....

Can anybody please help?

The object returned by Connect-VIServer is not an object type that is accepted by the Entity parameter on the Get-Stat cmdlet.

You could do:

$esx = Get-VMHost 192.168.1.1

$cpu = Get-Stat -entity $esx -Stat 'cpu.usage.average' - Realtime -maxsamples 1

How can I authenticate to my ESXi host?

[LucD]

With the root account from the ESXi server

Thank you for the whole of your help.

I am a PowerCLI novice, so I tryied all the possible syntaxes I can imagine with no success...

Can anybody please help providing a working sample based on a free ESXi hos?

Does this work ?

Try {

  Get-PSSnapin -Name VMware.VimAutomation.Core -ErrorAction Stop

}

Catch{

  Add-PSSnapin VMware.VimAutomation.Core

}

Connect-Viserver -Server 192.168.1.1 -user root | Out-Null

$esx = Get-VMHost

Get-Stat -entity $esx -Stat 'cpu.usage.average' -Realtime -MaxSamples 1

Disconnect-VIServer -Server 192.168.1.1
