Please, review my code!
It generates documents like this into a collection named as  <project name>_raw :
{
        "_id" : ObjectId("54241f4843f45617d17161fd"),
        "content" : "",
        "url" : "http://origin.api.hd-qa74.homedepotdev.com/
        "host" : "origin.api.hd-qa74.homedepotdev.com",
        "time_bucket" : [
                "2014-09-25 13:56-minute",
                "2014-09-25 13-hour",
                "2014-09-25-day"
        ],
        "date" : ISODate("2014-09-25T13:56:21.721Z"),
        "status_code" : 200,
        "method" : "GET",
        "response_time" : 0.1466970443725586
}
I've added both DEFAULT_TIMEOUT and DEFAULT_MONGO_URI
