Verifying That CNS NetFlow Collection Engine Is Running
To verify that CNS NetFlow Collection Engine is running properly, perform the following steps.
Step 1 To display a table of CNS NetFlow Collection Engine statistics, use the web-based user interface as
described in the “Status” section of the CNS NetFlow Collection Engine User Guide.
Step 2 Verify that the UDP ports that are expected to receive export data are receiving data. The status page of
the web UI should indicate that flows are being received.
Step 3 Check log files in NFC_DIR/logs for error messages.
If you are receiving data on the CNS NetFlow Collection Engine UDP port and there are no error
messages in the log files, CNS NetFlow Collection Engine is running properly.
You should periodically monitor the log files for error and warning messages.
