How to configure props and transforms with the proper regex to capture and assign hosts from a TCP data stream?

Hi,

I have a tcp data stream that has embedded hosts that I need to transform, and I'm hoping to get some regex help. Here's the stream:

2015-03-22 17:13:36 "myhost" some random and variable message text...

What would my transforms be set to? (The quotes are part of the message).

Be sure your syntax conforms with this example.
The transforms.conf stanza would look something like this:

[force_the_host]
REGEX = ^\d{4}-\d{2}-\d{2}\s+\d{2}:\d{2}:\d{2}\s\"([^\"]+)\"
FORMAT = host::$1
DEST_KEY = MetaData:Host

**Note the capturing group, just after the double quote says "anything that is not a double quote".

in props.conf you would have:

TRANSFORMS-force_host=force_the_host
With Splunk... the answer is always "YES!". It just might require more regex than you're prepared for!
