FDR Troubleshooting

If your collector isn't receiving flow detail records (FDRs) from your PacketShaper, try the suggestions below to troubleshoot the problem.

Verify Settings

Log in to your PacketShaper, go to the Flow Detail Record Settings setup page, and double-check the following:

• Is the collector's IP address correct?
• Did you specify the correct UDP port?
• Is the collector enabled?

Log in to your collector and verify the following:

• Is the collector listening?
• Is the collector listening on the same UDP port you have configured in PacketWise?
  

Test Network Connectivity

To verify that you can connect to the collector, use the ping command. For example, if the collector's IP address is 10.10.10.10, type ping 10.10.10.10 at the CLI prompt.

• If you are able to connect to the collector, you will see the message "10.10.10.10 is alive."
• If you are unable to connect, you will see the message "no answer from 10.10.10.10." The server may be down or you may have the wrong IP address for the collector.

You should also confirm that your collector can talk to your PacketShaper. For example, if your PacketShaper address is 192.21.20.190, log into your collector and type ping 192.21.20.190.

Verify that FDRs are Being Sent

As PacketWise sends UDP flow record packets to the collector, it records measurement data for the NetFlowV5 or FlowRecords class. To verify that PacketWise is emitting FDRs, log into your PacketShaper and go the Monitor Traffic screen.

• Does Outbound/Localhost have a class for NetFlowV5 or FlowRecords? The class is automatically created as soon as a collector is enabled. For example, if a Packeteer-2 collector is defined and enabled, PacketWise creates a FlowRecords class and this class will track all FDR traffic emitted to the defined Packeteer-2 collector. If a collector is defined, but not enabled, the class will not be created. In the example above, Outbound/Localhost/NetFlowV5 and Outbound/Localhost/FlowRecords classes were created.
• Does the Monitor Traffic screen show activity in the NetFlowV5 or FlowRecords class? If PacketWise is sending FDRs and they are being received by a collector, you should see values in the Class Hits, Current (bps), 1 Min (bps), and Peak (bps) columns. In the example above, the NetFlowV5 class does show active data, indicating flow records are being emitted and received; the FlowRecords class does not show any activity (FDRs are not being sent, perhaps because the collector is misconfigured).

Note: If your collector is on the LAN and FDR packets are being sent on the INSIDE link, you will not see any measurement data on the NetFlowV5 or FlowRecords classes. Measurement data is recorded on these classes only if FDR packets are sent to the OUTSIDE link.
