Issue

The device discovery fails regardless of the devices selected.

Solution

  • UDT Discovery always runs on main poller even if the nodes are affiliated with additional poller. Make sure the machine where main poller is installed has access to the selected device.
  • Make sure the SNMP requests/responses are not blocked by a firewall.
  • Verify that job engine services (JobEngine v2, Collector Polling Controller, Collector Data Processor, Collector Management Agent) are running.
  • Check the UDT.Jobs log to see if the discovery job finished successfully or shows an error.
  • Check the UDT.BusinessLayer log to see if the discovery job's results were processed successfully or shows an error.
