Hi,

I'm using python script to create json output for a custom sensor. In the json output I set 'text' field and this works ok for most of my devices, most of the time. However sometimes the value of the 'text' field is ignored and set to 'OK'.

Can you help me troubleshoot the problem?

Below is the output of the script as created by PRTG (text value is 'Unit (76) connected to Hulk NW AP' but in PRTG I only get 'OK'):

Hi there,

Please note that we cannot support custom scripts. However, if the issue occurs did you run the script manually to validate the text output?

This script has been tested and is in production environment, so I'm not asking for support in regards to the custom script. It works on 100+ devices most of the time.

All I'm reporting is that under some circumstances it returns 'OK' in the status message instead of what I supplied in 'text' field.

I have just noticed that when I restarted the probe yesterday, all devices started to return the correct message status which I supplied in the 'text' field of the script. Perhaps all I needed was to do just that - restart the probe after setting up devices.

It will be interesting to see if this issue resurfaces, in which case I will have to restart the probe service daily.

Thank you for your time.

Thank you for the feedback.

I would recommend to write an email to support@paessler.com if the issue occurs next time since it's easier to share log files and screenshots via email.
