Technology Add-on for NetFlow

Splunk AppInspect Passed
Admins: Please read about Splunk Enterprise 8.0 and the Python 2.7 end-of-life changes and impact on apps and upgradeshere.
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, Amazon AWS VPC Flow Logs.

This data is then visualized by Netflow Analytics for Splunk App

or by Splunk App for Enterprise Security

Download your free 60 day NetFlow Optimizer trial at https://www.netflowlogic.com/download/

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. 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:

        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:

        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:

        sourcetype = flowintegrator
        index = flowintegrator

Restart splunk for the configuration changes to take effect.
