[Help] Need PowerCLI script to monitor ESXi host and VMs in there

[vohuythao]

Dear all,

Could anyone help me to write a script for :

• check host status
• check each VM status
• email upon failure

Thank you for your kindly help

Best regards

[LucD]

Could you be more specific on what you want to check as status ?

Is that the powerstate, any alarms,.... ?

Thanks LucD

I want to check these things

-ESXI host :

+ ssh/telnet to the host

+ power status of the host

- VMs inside host

+ remote desktop connection the GuestOS on VM ( Windows)

+ power state of VMs

+ status of GuestOS ( hang/not responding or normal)

- send a cumulative email of all failures in one check

-script run every x minutes, we can configure this time

Thank you very much fot your help

That is quite a bit of code you want :smileygrin:

Let's take this step by step.

1) The ESXi powerstate

Quite simple, use the Get-VMHost cmdlet and check the PowerState property

Get-VMHost | Select Name,PowerState

2) The SSH service

Again reasonably simple

Get-VMHost | Get-VMHostService | where {$_.Key -eq 'TSM-SSH'} |

Select @{N='VMHost';E={$_.VMHost.Name}},Running

3) RDP on VM

One way of checking this is to verify if the Windows Firewall has the incoming RDP rule enabled.

netsh advfirewall firewall show rule name="Remote Desktop (TCP-In)"

This can be tested with the Invoke-VMScript cmdlet, but that requires VMware Tools to be installed.

Is that the case ?

Can you do an Invoke-VMScript against all the VMs that run a Windows guest OS ?

4) VM powerstate

A simple one

Get-VM | Select Name,PowerState

5) Guest OS

Not sure how you want to test this.

Would a ping be sufficient ?

Thanks LucD so much,

3) RDP on VM

All VMs had vmware tools installed

sorry that I don't have any idea about Invoke-VMScript

Could you please help to write a code that use Invoke-VMScript?

5) GuestOS

I think a ping test would be fine for this

Thank you very much for your help

Hi LucD,

I got the function send email already, but I am still confused about the structure of script?

The condition, if...else

- Check the ESX host is alive or not ( could we use ping?)

+ If ok, check whether we can SSH to it

+ If not, send email report

Next, if ESX host is ok

+ Check VMs power state

+ Check RDP to VMs

+ If not, send email report

Thank you for your very kindly help
