how to get (and then modify) all notification Threshold > 90 %

Hi,

I am looking for a way to programmaticaly retrieve all Threshold notification that are set with a threshold of 90% to change the action from an email to SMS. Unfortunately we are using the same template for all our notification, making it impossible to edit it.

I found PRTGApi and started to play with it, but I cannot manage to retrieve notificationTrigger based on the threshold value. Does anybody know if it is possible to achieve ?

For instance, this is working :

PS C:\WINDOWS\system32>  Get-Sensor -Id 13307 | Get-NotificationTrigger

Type      ObjectId SubId Inherited ParentId Latency Condition Threshold Unit       OnNotificationAction
----      -------- ----- --------- -------- ------- --------- --------- ----       --------------------
Threshold 13307    3     False     13307    600     Above     90                   Email to all members of group ITS-PRTG-Admins
Threshold 13307    4     False     13307    600     Above     90                   Email to all members of group ITS-PRTG-Admins
Threshold 13307    1     False     13307    14400   Above     70                   Email to all members of group ITS-PRTG-Admins
Threshold 13307    2     False     13307    14400   Above     70                   Email to all members of group ITS-PRTG-Admins

But from there, I am stuck...
Thank you very much for your help,
Schlum

Get-Sensor -Id 13307 | Get-NotificationTrigger | Where-Object {$_.Type -like "Threshold" -and $_.Threshold -ge 90}
