I am using a light forwarder to send the log to the indexer, so I am guessing that is a intermediary?
[hostoverride]
REGEX = host=([a-zA-Z0-9.-_]+)
DEST_KEY = MetaData:Host
FORMAT = host::$1
[netwitness-extractions]
REGEX = CEF:\d+|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|([^|])|
FORMAT = nullQueue
