[jira] [Commented] (METRON-854) Create DHCPDump Parser
[ https://issues.apache.org/jira/browse/METRON-854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16121278#comment-16121278 ]

@simonellistonball after some testing we concluded that Bro is not giving the output we want (source: https://bro-tracker.atlassian.net/browse/BIT-1630). The output doesn't contain hostnames, so the relation IP / Hostname can't be made. I still agree on modifying the source, DHCPDump, is not the preferred way to go. Can you assist in how to ship and parse multi-line log events, so I can adjust the parser accordingly without messing with the source?
Thanks
