Passing host name to triggered alarm

[Dinu26]

Have configured alarm action to run a command, Is there a way for me to pass the Esxi host name for which the alarm has been triggered ?

TIA

When an Alarm is fired, there are a number of environment variables available, see Alarm Environment Variables for Scripts.

The hostname is in VMWARE_ALARM_EVENT_HOST.

Hi LucD,

Thanks Much for the response.

Am being dumb here,

Have tried passing the host name through alarm as well as script, But am unable to figure it out.

I tried with TargetName and VMWARE_ALARM_TARGET_NAME but no luck

Below is what I have in TT.cmd.

Set Parm1= {VMWARE_ALARM_TARGET_NAME}

echo "am being called" >> "C:\ProgramData\VMware\VMware VirtualCenter\scripts\test.txt"

echo Parm1 >> "C:\ProgramData\VMware\VMware VirtualCenter\scripts\test.txt"

C:\Windows\System32\cmd.exe /c powershell.exe -noninteractive -noprofile -file "C:\ProgramData\VMware\VMware VirtualCenter\scripts\tt.ps1" %Parm1%

Below is the code in tt.ps1

[CmdletBinding()]

Param(

[Parameter(Mandatory=$True,Position=1)]

[string]$Test

)

write-host $Test

$ExchangeServer = "***********"

$FromAddress = "**********"

$to = "**************"

$te =  "Am being called by Alarm"

$te | Out-File -filepath "C:\ProgramData\VMware\VMware VirtualCenter\scripts\test.txt" -Append

Send-MailMessage -from $FromAddress -To $to -Body "test 1 and $Test" -Subject "top" -SmtpServer $ExchangeServer

Have a look at Horst's (oldish) document named Fun with vSphere Alarms​

In section 5 of that document he demonstrates a method to discover all environment variables that are available when an alarm is fired.
