Thank you for the clarification.
Please note that you don't need to fill in all settings within the Python Script Advanced Sensor, as not all of them are relevant for the sensor operations.
For example, you can leave the fields "Parent Tags" and "Tags" as they are.
By default, the sensor uses security context of probe service (Windows system user account).
Under "Device Credentials" you can define if you want to transmit device credentials to the Python script (e.g. if Windows or Linux or SNMP credentials are needed).
"Additional parameters" depend on the script; if they are not needed, you can leave this field empty.
You can also leave the field "Mutex Name" empty.
So, the only crucial parameter in the sensor settings is the python script. Please make sure the script is stored under "C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\python" on the PRTG Probe.
