Network Monitoring Modes

Session Monitor probes can use two modes of monitoring network mode:

  • mmpcap: The mmpcap mode is based on the libpcap Packet Capture Library similar to tcpdump, using the Kernel's Packet Socket Interface. The network interface is set to promiscuous mode.
  • Data Plane Development Kit (DPDK): DPDK is a set of data plane libraries and network interface controller drivers for fast packet processing. In this mode, the network interface is no longer accessible by the Kernel. You can find more information regarding the DPDK libraries in the website, http://dpdk.org.

By default, the installer enables the mmpcap mode which is recommended for small to medium installations (for up to 1400K pps depending on server capabilities). For higher network traffic solutions, you may choose to enable DPDK mode for better performance. For more information on DPDK, see Installing and Configuring DPDK for Session Monitor.

Note:

The above number is only for reference. The actual decision on when to use DPDK depends on many factors. For consulting regarding this decision, Oracle recommends to complete a sizing exercise together with your Oracle sales engineer.
