powershell Get Envirennement Variable from Notification's placeholders

Votes:

0

Hello,

I have a script powershell to purge Exchnage Logs, and I configured a Notification template to launch this script on the Exchange servers when the Espace disk sesnsors "C:" get error status,

My script is the follow :


# Set-Executionpolicy RemoteSigned

# Utilisateur :
$username = "Domine\Administrator_Account" 

# Le chemin du fichier script pour purger les logs exchange :
# $exchLogPurgeCodePS = "C:\Program Files (x86)\PRTG Network Monitor\Notifications\EXE\exch_2013_purge_logs_15j.ps1"

# l'IP ou Nom DNS du serveur Exchange diatant
#$RemoteComputers= "@IP_EXCH_SRV"
# param(
# [string]$RemoteComputers = $host
# )
<#
# TODO  : 
#  
param(
[string]$RemoteComputers = %host
)
#>
$Env:RemoteComputers = $host
# [Environment]:SetEnvironmentVariable('RemoteComputers',$host)
# Chiffrer le MDP du compte Admin, et le mettre dans le fichier "cryptedpass.txt"
<#
$cryptedpass = $userPassword | ConvertTo-SecureString -AsPlainText -Force | ConvertFrom-SecureString | Out-File "cryptedpass.txt"
echo $cryptedpass
#>

$pass = Get-Content "cryptedpass.txt" | ConvertTo-SecureString
$File = "cryptedpass.txt"
$MyCredential = New-Object -TypeName System.Management.Automation.PSCredential `
 -ArgumentList $userName, (Get-Content $File | ConvertTo-SecureString)
 echo $MyCredential


<# S'il y a plusieurs serveurs surlesquels il faut lancer le script

$RemoteComputers= get-content "servers.txt"
#>


# Tester la connxion WMI sur tous le(s) serveur(s)
ForEach ($RemoteComputer in $RemoteComputers)

{

If (Test-WSMan -ComputerName $RemoteComputer)

{
echo "CONNECTION TO SERVER...."
# Connexion au serveur distant via l'objet (Variabel) "$MyCredential" 
Invoke-Command -ComputerName $RemoteComputer -Credential $MyCredential -ScriptBlock {

##############################################  
HERE MY SCRIPT TO PURGE EXCHANGE LOGS
##############################################


}

}

}

In my script I tried to pass PRTG %host placeholder to Powershell as following, but I never succeeded to do it.

##### 1. 
# param(
# [string]$RemoteComputers = $host
# )

##### 2.
<#
param(
[string]$RemoteComputers = %host
)
#>

##### 3.
#$Env:RemoteComputers = $host


##### 4.
# [Environment]:SetEnvironmentVariable('RemoteComputers',$host)

So, I hope you can help me on this case, can you guide me how can I use Notificatiosn's placeholders in my powershell code please ?

Thank you very much.

Best regards,

Hi,

To passe the device'IP to my script powershell, in my script I tried again like follow :

# Set-Executionpolicy RemoteSigned
$username = "domaine\administrateur" 


param(
[string]$host
)

and in my notification template I did : 

# Execute Program : 
Program File : MyScript.ps1

parameters  : '%host'

I wait that the sensor get error status to launch the notification that used for this script.

Have you tested your script outside of PRTG?
Is the problem only with the placeholder for the device address, or do you get a error in PRTG for this notification type?

Kind regards,
