This article applies to PRTG Network Monitor 19 or later


The syntax provided in this article is not fully compatible with the HTTP XML/REST Value sensor. This sensor type does not officially support the use of XPath and we cannot give you any technical support regarding XPath issues.

This article is provided for your information only.


In the XML Node (and optional property) setting of the HTTP XML/REST Value sensor, you can try to use XPath, which can enable you to read, for example, values of arrays from XML files. For example, use array[@name='myName'] to read all 'array' elements that have a 'name' attribute equal to 'myName'. A few more examples:

Get all sensors with a certain status: //status[text()='green']
Get all HTTP-based sensors from the PRTG configuration file (using PowerShell): sensor[@id][data/sensorkind[normalize-space(text())="http"]]
