Update to the latest Logstash Schema

[joekiller]

Hello,

Logstash has updated their spec for schema:

https://logstash.jira.com/browse/LOGSTASH-675

{
  "@timestamp": "2012-12-18T01:01:46.092538Z".
  "@version": 1,
}

those are the only two fields that need an "@" sign and @fields is no longer required.

ie:

{
  "account": "pyr",
  "args": [],
  "created": 1367480388.013037,
  "exception": [
    "Traceback (most recent call last):\n",
    "  File \"toto.py\", line 16, in <module>\n    k['unknown']\n",
    "KeyError: 'unknown'\n"
  ],
  "filename": "toto.py",
  "funcName": "<module>",
  "levelname": "WARNING",
  "levelno": 30,
  "lineno": 18,
  "module": "toto",
  "msecs": 13.036966323852539,
  "name": "root",
  "pathname": "toto.py",
  "process": 1819,
  "processName": "MainProcess",
  "relativeCreated": 18.002986907958984,
  "thread": 140060726359808,
  "threadName": "MainThread"
  "message": "TOTO",
  "source_host": "phoenix.spootnik.org",

}

This basically converts something like

{
    "@fields": {
        "relativeCreated": 6251.781940460205,
        "process": 5342,
        "args": [],

        "threadName": "MainThread",
        "msecs": 240.01002311706543,
        "filename": "go.py",
        "levelno": 20,
        "processName": "MainProcess",
        "pathname": "/path/to/gun.py",
        "lineno": 177,
        "levelname": "INFO"
    },
    "@timestamp": "2013-10-17T19:48:40.240067Z",
    "@source_host": "localhost.local",
    "@message": ""
}
