No NetFlow data on the NTA/UBA server

To resolve the problem:

• Verify that the same UDP port number for log receiving is configured on the device as configured on the NTA server.

• Verify that the device and the NTA server can reach each other.

• Check the firewall status on the NTA server. If the firewall is enabled, disable the firewall, or bring up UDP ports 9020, 9021, and 6343.

• Check the size of files in the directories $IMC_INSTALL/data/recieverData and $IMC_INSTALL/data/processorData/data. If a large number of files exist in the directories, clear files from the installation directory and the database:

  1. Stop the processor and receiver processes.

  2. Delete all files in directories $IMC_INSTALL/data/recieverData and $IMC_INSTALL/data/processorData/data.

  3. Delete the receivedfile.txt file in directory $IMC_INSTALL/unba/conf.

  4. Clear the unba_slave.tbl_storing_task table from the unba_slave database.

  5. Restart the processor and receiver processes.

• Check the database disk usage on the Service > Traffic Analysis and Audit > Database Space page. If the disk usage has exceeded the usage threshold of the database disk, expand the disk capacity or delete useless data.
