I've created a custom string sensor using a regex to covert to floating. I'm getting the appropriate value back, but PRTG is not making a channel for that data and the response time channel is showing no data/alarm. Thoughts?

Article Comments

Joshua,

thank you for the KB-Post. To allow us a better overview of what is going on, please send us the following screenshots of the affected sensor (out of the PRTG AJAX Webinterface):
- the "Overview" tab,
- the "Log" tab,
- the "Settings" tab (multiple screenshots if necessary to cover all options).

Please make sure the screenshots show the entire user interface, and aren't cropped.

It's got to be an issue with the regular expression. Can you give me the full string that the device returns without any filtering? Then I can run some tests, and hopefully suggest another working expression.

Please give

\d+.\d+

a try. Keep '.' as decimal separator with that.
