Technology Add-on for NetFlow

Splunk Certified
Overview
Details
This technology add-on collects NetFlow data processed by NetFlow Optimizer™ (NFO) software.

NFO supports NetFlow v5, v9, sFlow, J-Flow, IPFIX, Cisco ASA NSEL, Cisco HSL, Cisco AVC, Palo Alto Networks NetFlow.

This data is then visualized by Netflow Analytics for Splunk App
(https://splunkbase.splunk.com/app/489/)

or by Splunk App for Enterprise Security
(https://splunkbase.splunk.com/app/263/).

Technology Add-on for Netflow relies on flow data processed by NetFlow Optimizer and enables you to analyse it using Splunk® Enterprise or Splunk Cloud.

It provides CIM compliant field names, eventtypes and tags for NetFlow Optimizer data.

The Add-on can also be used to generate sample events for testing purposes, it contains samples of netflow data and config files for the event generator.

Setup after installation:


  1. Starting from this version the UDP data input on port 10514 is no longer configured by default, and it should be added manually. The TA-netflow is expecting that the sourcetype of events sent from Netflow Optimizer would be set to "flowintegrator". To set it up please create the $SPLUNK_ROOT/etc/apps/TA-netflow/local/inputs.conf file, and add the following lines to it:

        [udp://10514]
        sourcetype = flowintegrator
    

  2. By default NetFlow Optimizer events will be stored in main index. In case you want to use another index, please create the $SPLUNK_ROOT/etc/apps/TA-netflow/local/indexes.conf file, and add the following lines to it:

        [flowintegrator]
        homePath    = $SPLUNK_DB/flowintegrator/nfi_traffic/db
        coldPath    = $SPLUNK_DB/flowintegrator/nfi_traffic/colddb
        thawedPath  = $SPLUNK_DB/flowintegrator/thaweddb
    

    You also need to make sure your $SPLUNK_ROOT/etc/apps/TA-netflow/local/inputs.conf file contains the following:

        [udp://10514]
        sourcetype = flowintegrator
        index = flowintegrator
    

Restart splunk for the configuration changes to take effect.
