I want to use the REST Custom v2 sensor with XPath or JSON. Are there any recommended resources that can help me understand these topics in relation to PRTG?
Rest Custom v2
The REST Custom v2 sensor queries a JSON or XML REST API endpoint and maps the result to sensor values. While this makes the sensors very flexible and applicable to many situations, it helps to have a strong understanding of JSONPath and XPath in order to configure queries to work with PRTG exactly as you want them to.
There are endless resources on the internet, but we've collected some of our favorites below.
