How can I monitor a string in the HTML of a webpage?

I want to monitor a value in the HTML of a web page.

Depending on the returned values the sensor should show different states and different sensor messages.

The values on the web page I want to monitor are in a similar format that you would use for the HTTP Content sensor:

[integer][string]

The HTTP Content sensor can only monitor integers, not strings.

How can I achieve my goal?

This article applies to PRTG Network Monitor 12 or later

Monitoring Strings in the HTML of Web Pages

In order to process the HTML of web pages to receive sensor states corresponding to the returned values in the format [value][string], you can use a custom sensor with a script file. Create a powershell script for this issue and add it to an EXE/Script Advanced Sensor in PRTG.

For more details and a basic script, please refer to the following article: Monitor 1 value, on error send 2nd value.
