Monitor file compare




Is it possible to monitor two different folders with multiple files for example:

location a location b

Then do a compare of all files in location a and b and set a trigger when the date modified is 15 minutes older of a file in location b than the same file in location a?

Thanks R.

thank you very much for your KB Post. I'm very much afraid the inbuilt Folder-Sensor is not that flexible. A custom script sensor will be necessary here.

best regards

Thank you very much. If i just attach the script to the sensor, will that be enough? How is the custom script sensor able to determine and display the outplut of the script?

Thanks R.

The response of the script needs to be in a format that PRTG accepts:


For more details, please see your very own PRTG under "Setup"->"PRTG API"->"Custom Sensors".
