Sending JSON on sensor Error.

Hello,

Thank you for your message.

To send a JSON when a sensor goes in down state, you can use the Execute Program action of the notification template and then pass the values you desire (could be placeholders) to the custom script.

You will find the available placeholders for notifications in this manual: https://www.paessler.com/manuals/prtg/list_of_placeholders_for_notifications

If you have questions, do not hesitate.

Regards.

Thank you for the link. I have a new problem, unable to forward placeholders to script Powershell :( Please tell me where can I find examples of Powershell scripts passing placeholders? If possible, tell me how placeholders are passed correctly.

Hello,

Thank you for your feedback.

To use placeholders with the script, you have the possibility to use named parameters in PowerShell. To do so, in your script you must have the following placed at the beginning:

Param (
    $Param1 = "",
    $Param2 = ""
    ...
)

Then, in your script you can use these variables in your code.

In PRTG, you have two options to configure the placeholders to sent to the script, as illustrated below:

• Add placeholders in the corresponding order (within quotation mark)

"%placeholder1" "%placeholder2"

• Provide the name of the parameter and the argument you want to pass to it:

-Param1 "%placeholder1" -Param2 "%placeholder2"

Here is an article which shows how to use parameters in PowerShell: https://www.red-gate.com/simple-talk/sysadmin/powershell/how-to-use-parameters-in-powershell/

When configuring the notification template, you need to provide the placeholders in the Parameters field of the action "Execute Program".

Regards.
