Using Fastcapa

You can use the Fastcapa tool to capture high-volume data flow.

1. Create a configuration file that, at a minimum, specifies your Kafka broker:

   [kafka-global]
   metadata.broker.list = kafka-broker1:9092
   

   You can view the example configuration file conf/fastcapa.conf to learn other useful parameters.
2. If the capture device is not bound, bind it:

   ifdown enp9s0f0
   modprobe uio_pci_generic
   $DPDK_HOME/sbin/dpdk-devbind --bind=uio_pci_generic "09:00.0"

3. Run Fastcapa:

   fastcapa -c 0x03 --huge-dir /mnt/huge_1GB -- -p 0x01 -t pcap -c /etc/fastcapa.conf
   

4. Terminate Fastcapa and clear the queue by usingSIGINT or by typing CTRL-C.
   The probe will cleanly shut down all of the workers and allow the backlog of packets to drain.
   To terminate the process without clearing the queue, use SIGKILL or enterkillall -9 fastcapa.
