ScribeHandler 0.05

ScribeHandler is a simple proxy layer that works with the python standard
logging module (http://docs.python.org/library/logging.html). ScribeHandler
acts a a handler object that gets added to a logger in the standard way.

Important bits:

When instantiating the handler, you will want to specify the connection
setting to scribed. The following keyword arguments are reconized (and
defaults):

Argument Default
---------------------------
host 127.0.0.1
port 1463
category %(hostname)s-%(loggername)s
transport ScribeHandler.FRAMED
uri None

- Host and port, should be obvious

- If transport is ScribeHandler.FRAMED, then
thrift.transport.TTransport.TFramedTransport() is used.
- If transport is ScribeHandler.BUFFERED, then
thrift.transport.TTransport.TBufferedTransport() is used.
- If transport is ScribeHandler.HTTP then
thrift.transport.THttpClient.THttpClient() is used and uri MUST NOT be
None
- If transport is None then you can assign any acceptable Thrift/Scribe
transport via

ScirbeHandler.transport = <transport>

where <transport> is a valid Scibe/Thrift transport (this is an attempt at
future proofing).

- category is translated into the category parameter to scribe.LogEntry()
object. It should be a standard format string using mapping keys.
The following are the reconized mapping keys:

Key Name Source
----------------------
module logging.LogRecord.module
levelname logging.LogRecord.levelname
loggername logging.LogRecord.name
processname logging.LogRecord.processName
hostname socket.gethostname()


Here's a simple example of how to use it:

import logging
import ScribeHandler
mylogger = logging.getLogger('ScribeLogger')
mylogger.setLevel(logging.DEBUG)
handler = ScribeHandler.ScribeHandler(category='%(hostname)s-%(levelname)s', file_buffer='/tmp/logbuffer')
mylogger.addHandler(handler)

mylogger.debug('stuff happens')
