> Issue Type: Improvement
> Reporter: Andre

> Fix For: 1.1.0
>
>
> As NiFi continue to increase its abilities to complement SIEM, Splunk and ELK
> deployments, a number of users will be looking to parse CEF formatted
> logs[1][2].
> CEF is a format specified by Arcsight (now part of HPE) and is described in
> detail in here:
