Well, here it comes! With the new PRTG release 17.3.33, we are pleased to introduce the all new **REST Custom Sensor**. [![take a rest and monitor everything](https://blog.paessler.com/hubfs/header/blog/914350_REST-Custom-Sensor.RZ.png)](https://blog.paessler.com/take-a-rest-and-monitor-everything) This sensor is a powerful tool that goes far beyond standard monitoring. You can query any REST API that returns JSON or XML and map the results into sensor channels. And the REST Custom sensor is even smarter: it comes with an automatic detection feature for JSON or XML responses and creates suitable channels on its own! ![The REST Custom Sensor showing weather information from Weather Underground](https://blog.paessler.com/hs-fs/hubfs/screenshots/Screenshot-Environmental_Information_Nuremberg_Sensor_Details.png?width=1024&name=Screenshot-Environmental_Information_Nuremberg_Sensor_Details.png "The REST Custom Sensor showing weather information from Weather Underground") **The REST Custom Sensor showing weather information from Weather Underground** We also deliver various REST configuration files for this sensor, so you can immediately see and try out what might be possible with your own REST Custom sensor. You can find the samples in the \\Custom Sensors\\rest folder in the PRTG program directory, including ready-to-use mappings for: - KEMP load balancers - Weather Underground - [Docker containers](https://www.paessler.com/docker-monitoring) - …and PRTG itself Learn more about the new REST Custom Sensor in our [manual](https://www.paessler.com/manuals/prtg/rest_custom_sensor).
