How can I use the push notification application "ntfy" with PRTG?

Using the script below, you can use the script notification with the following parameters to send a notification through the ntfy service.

Parameters

NTFY_ENDPOINT "[%sitename]" "%device" "%name" "%status" "%down" "(%message)"

Script (Powershell)

$ntfy_url = $args[0]

$site = $args[1]
$device = $args[2]
$name = $args[3]
$status = $args[4]
$down = $args[5]
$message = $args[6]

$pushMessage = @"
Site: $site
Device: $device
Name: $name
Status: $status
Down: $down
Message: $message
"@

Invoke-WebRequest -Uri $ntfy_url -Method POST -Body $pushMessage

If you are hosting your own ntfy server, you can also make sure it's up and running by setting up a REST Custom v2 sensor. The following settings work to show if it's up or down:

Request URL: NTFY_URL/v1/health

Channel #1 JSONPath/XPath: $.healthy

Channel #1 Value Type: Status (string)

Channel #1 Strings mapped to the 'Up' status: true
