If you are running PRTG or a Remote Probe of PRTG on a Windows 2003 Server please take a look at the following article:

This article applies to PRTG Network Monitor 13.3.7 or later

VMware (SOAP) Sensor with "Unknown Error" Message

PRTG displays this message when a VMware (SOAP) sensor internally runs into an uncaught error.

In order to help us fixing this error, please run the sensor manually in debug mode. This will generate a debug logfile which can support us in order to identify the problem.

Generating the Debug Logfile

On PRTG-installations with version 15.3.19 or later you can generate the debug-log using the build-in 'Write sensor result to disk'-mechanism which can be set up on the settings-tab of the sensor.

On older installations there is some manual work necessary:
Open a Windows command line and run the following command (after replacing the placeholders in '<>' with the according values):

'<path to your PRTG installation>\Sensor System\<sensor-executable>' -u=<username> -p=<password> -s=<server> -m=<MoID> -debug=<path>

Replace the placeholders in brackets the following way:

  • path to your PRTG installation: can be obtained from this article
  • sensor-executable: use VMWareSensor.exe for VMware (SOAP) sensor types:
    • VMware Host Hardware Status (SOAP) sensor
    • VMware Host Performance (SOAP) sensor
    • VMware Virtual Machine (SOAP) sensor
  • username: the username to authenticate against the server
    • use domain\username when running against a vCenter server
    • use username when running against an ESX(i) host directly
  • password: use the corresponding password
  • server: the FQDN or IP address of the host or vCenter
  • MoID: the Managed Object ID which you can find in the sensor settings tab in your PRTG installation
  • path: the directory on your file system where PRTG will store the debug log. PRTG will create a file with the name
    <sensor-executable-name>_<MoID>_<starttime>.log
    in this directory.

Please send this file to support@paessler.com for a detailed investigation of the problem.
