How Get Bluecoat CacheFlow log in splunkstorm

Hi

I'm trying to send a log from Bluecoat Cacheflow 5000 to splunkstorm with the format listed below

type elff "date time c-ip sc-bytes cs-bytes rs-bytes sr-bytes cs-host"

I am interested to get only the source address and host domain of all the conections crossing by the cacheflow.

I don´t have problem sending those logs to splunkstorm, but the information gathering is displayed in an unreadable format.

Does anybody know how make these posible.

Thanks in advance
