How to Collect the 3PAR Sensor Debug Information

Updated: May 17

Your experience using the AutoMonX 3PAR Sensor Pack for PRTG is important to us. If you encounter any difficulties we recommend that you open a case with our support team at This will help us improve your experience and increase efficiency.

In the support process we might need the debug logs, here is how to activate the service debugger:

  1. Open the sensor “Settings”window.

  2. Add the -dbg parameter the “Parameters” field.

During Debug mode, a special file is created. This file tracks all the 3PAR Sensor operations. The debug file needs to be examined by the AutoMonX support team to detect any issues.

The debug file will be named:


The file will be located in

<DISK>:\ProgramData\Paessler\PRTG Network Monitor\Logs (Sensors)

Starting with release 20.x of PRTG, logs have been moved to:

<DISK>:\ProgramData\Paessler\PRTG Network Monitor\Logs\sensors

In order to collect debug information on a specific VLUN sensor, follow these steps:

  1. Open the VLUN sensor "Settings" window,

  2. Add the -dbg parameter to the "Parameters" field

This will activate the debug mode upon the next start of the sensor.

The debug file will be named:


The file is located in the PRTG sensors logs directory:

<DISK>:\ProgramData\Paessler\PRTG Network Monitor\Logs (Sensors)

or (for release 20.x of PRTG):

<DISK>:\ProgramData\Paessler\PRTGNetwork Monitor\Logs\ sensors

Additionally to the debug log, please make sure to send the output of the showversion command and a screenshot of the Check Config output
