Sprockets InfluxDB
==================
Buffering InfluxDB client and mixin for Tornado applications
|Version| |Downloads| |Status| |Coverage| |License|
Installation
------------
``sprockets-influxdb`` is available on the Python package index and is installable via pip:
.. code:: bash
pip install sprockets-influxdb
Documentation
-------------
Documentation is available at `sprockets-influxdb.readthedocs.io <https://sprockets-influxdb.readthedocs.io>`_.
Configuration
-------------
Configuration can be managed by specifying arguments when invoking
``sprockets_influxdb.install`` or by using environment variables.
For programmatic configuration, see the
`sprockets_influxdb.install <https://sprockets-influxdb.readthedocs.io/en/latest/api.html#sprockets_influxdb.install>`_
documentation.
The following table details the environment variable configuration options.
+-----------------------+-------------------------------------------------+---------------+
| Variable | Definition | Default |
+=======================+=================================================+===============+
| ``INFLUXDB_SCHEME`` | The URL request scheme for making HTTP requests | ``https`` |
+-----------------------+-------------------------------------------------+---------------+
| ``INFLUXDB_HOST`` | The InfluxDB server hostname | ``localhost`` |
+-----------------------+-------------------------------------------------+---------------+
| ``INFLUXDB_PORT`` | The InfluxDB server port | ``8086`` |
+-----------------------+-------------------------------------------------+---------------+
| ``INFLUXDB_USER`` | The InfluxDB server username | |
+-----------------------+-------------------------------------------------+---------------+
| ``INFLUXDB_PASSWORD`` | The InfluxDB server password | |
+-----------------------+-------------------------------------------------+---------------+
Mixin Configuration
^^^^^^^^^^^^^^^^^^^
The ``sprockets_influxdb.InfluxDBMixin`` class will automatically tag measurements
with the application/service name if the ``SERVICE`` environment variable is set. It will
also tag the measurement if the ``ENVIRONMENT`` environment variable is set with the environment
that the application is running in. Finally, if you are using the
`Sprockets Correlation Mixin <https://github.com/sprockets/sprockets.mixins.correlation>`_,
measurements will automatically be tagged with the correlation ID for a request.
Example
-------
In the following example, a measurement is added to the ``example`` InfluxDB database
with the measurement name of ``measurement-name``. When the ``~tornado.ioloop.IOLoop``
is started, the ``stop`` method is invoked, calling ``~sprockets_influxdb.shutdown``.
``~sprockets_influxdb.shutdown`` ensures that all of the buffered metrics are
written before the IOLoop is stopped.
.. code:: python
import logging
import sprockets_influxdb as influxdb
from tornado import ioloop
logging.basicConfig(level=logging.INFO)
io_loop = ioloop.IOLoop.current()
influxdb.install(io_loop=io_loop)
measurement = influxdb.Measurement('example', 'measurement-name')
measurement.set_tag('foo', 'bar')
measurement.set_field('baz', 1.05)
influxdb.add_measurement(measurement)
def stop():
influxdb.shutdown()
io_loop.stop()
io_loop.add_callback(stop)
io_loop.start()
