The device discovery fails when it's done for specific devices.


  • UDT Discovery runs on the poller the nodes are affiliated with (i.e. it respects main and additional polling engines) since UDT 2.5. Make sure the machine where appropriate poller is installed has access to the selected device.
  • Run UDT Compatibility Checker (discovery target ) from machine with the right polling engine against the device and check the results.
  • Increase Port/Layer3 Discovery Job Timeout (Advanced Settings page)
  • Increase SNMP Timeout (Advanced Settings page)
