I have a custom sensor that returns:

<?xml version="1.0" encoding="WINDOWS-1252"?> -<prtg>-<result><channel>AO 3 COPPER</channel></result> <result><channel>AO 3 COPPER Status</channel></result> </prtg>

(I've eldided the data) when OK, but returns:

<?xml version="1.0" encoding="WINDOWS-1252"?> -<prtg><text>No recent values</text><error>1</error></prtg>

when there is a problem.

When I start getting data again, the sensor seems to get stuck in 'warning'/yellow status.

Similarly, if I run my custom sensor under a debugger and interrupt it, I get the 'error status' (red), and 'Last Message: Error reading response: missing /prtg'.

When I start sending valid xml to PRTG again, the 'last message' persists, and the sensor stays red (error).

Any ideas how to rectify this?

Hi,
please send the full output of the script and the script itself to support@paessler.com. Additional, please activate the debug option for the script in the tab Settings of the sensor. Therefore just set the option Result Handling to Write Result to Disk. This will create a file called REsult of Sensor XXXX.txt in the \Logs (Sensors) sub folder of your data directory. Please include this file as well.
Best regards
