statsd is a client for Etsy's statsd server, a front end/proxy for the Graphite stats collection and graphing server.

Install

To install simply execute python setup.py install. If you want to run the tests first, run python setup.py nosetests

Usage

To get started real quick, just try something like this:

Basic Usage


Timers
^^^^^^

    >>> import statsd
    >>>
    >>> timer = statsd.Timer('MyApplication')
    >>>
    >>> timer.start()
    >>> # do something here
    >>> timer.stop('SomeTimer')


Counters
^^^^^^^^

    >>> import statsd
    >>>
    >>> counter = statsd.Counter('MyApplication')
    >>> # do something here
    >>> counter += 1


Gauge
^^^^^

    >>> import statsd
    >>>
    >>> gauge = statsd.Gauge('MyApplication')
    >>> # do something here
    >>> gauge.send('SomeName', value)


Raw
^^^

Raw strings should be e.g. pre-summarized data or other data that will
get passed directly to carbon.  This can be used as a time and
bandwidth-saving mechanism sending a lot of samples could use a lot of
bandwidth (more b/w is used in udp headers than data for a gauge, for
instance).



    >>> import statsd
    >>>
    >>> raw = statsd.Raw('MyApplication', connection)
    >>> # do something here
    >>> raw.send('SomeName', value, timestamp)

The raw type wants to have a timestamp in seconds since the epoch (the
standard unix timestamp, e.g. the output of "date +%s"), but if you leave it out or
provide None it will provide the current time as part of the message

Average
^^^^^^^

    >>> import statsd
    >>>
    >>> average = statsd.Average('MyApplication', connection)
    >>> # do something here
    >>> average.send('SomeName', 'somekey:%d'.format(value))


Connection settings
^^^^^^^^^^^^^^^^^^^

If you need some settings other than the defaults for your ``Connection``,
you can use ``Connection.set_defaults()``.
    
    >>> import statsd
    >>> statsd.Connection.set_defaults(host='localhost', port=8125, sample_rate=1, disabled=False)

Every interaction with statsd after these are set will use whatever you
specify, unless you explicitly create a different ``Connection`` to use
(described below).

Defaults:

- ``host`` = ``'localhost'``
- ``port`` = ``8125``
- ``sample_rate`` = ``1``
- ``disabled`` = ``False``


Advanced Usage
--------------

    >>> import statsd
    >>>
    >>> # Open a connection to `server` on port `1234` with a `50%` sample rate
    >>> statsd_connection = statsd.Connection(
    ...     host='server',
    ...     port=1234,
    ...     sample_rate=0.5,
    ... )
    >>>
    >>> # Create a client for this application
    >>> statsd_client = statsd.Client(__name__, statsd_connection)
    >>>
    >>> class SomeClass(object):
    ...     def __init__(self):
    ...         # Create a client specific for this class
    ...         self.statsd_client = statsd_client.get_client(
    ...             self.__class__.__name__)
    ...
    ...     def do_something(self):
    ...         # Create a `timer` client
    ...         timer = self.statsd_client.get_client(class_=statsd.Timer)
    ...
    ...         # start the measurement
    ...         timer.start()
    ...
    ...         # do something
    ...         timer.intermediate('intermediate_value')
    ...
    ...         # do something else
    ...         timer.stop('total')

If there is a need to turn *OFF* the service and avoid sending UDP messages,
the ``Connection`` class can be disabled by enabling the disabled argument::

    >>> statsd_connection = statsd.Connection(
    ...     host='server',
    ...     port=1234,
    ...     sample_rate=0.5,
    ...     disabled=True
    ... )

If logging's level is set to debug the ``Connection`` object will inform it is
not sending UDP messages anymore.
