Netflow Module README

Configuration

There is only one variable associated with netflow, which is the port on which to listen for traffic.

The default port is 2055.

For Elasticsearch-specific configuration—which is common to all modules—see the official Logstash documentation.

Launching from the command-line

$LS_HOME/bin/logstash --modules netflow -M netflow.var.input.udp.port=XXXX

Adding to logstash.yml

Ensure these lines are properly added to your logstash.yml:

modules:
  - name: netflow
    var.input.udp.port: XXXX

With this properly configured, when Logstash is started, it will run the module.
