Quick Start
-----------

In order to use this library, you first need to go through the following steps:

1. `Select or create a Cloud Platform project.`_
2. `Enable billing for your project.`_
3. `Enable the Stackdriver Logging API.`_
4. `Setup Authentication.`_

.. _Select or create a Cloud Platform project.: https://console.cloud.google.com/project
.. _Enable billing for your project.: https://cloud.google.com/billing/docs/how-to/modify-project#enable_billing_for_a_project
.. _Enable the Stackdriver Logging API.:  https://cloud.google.com/logging
.. _Setup Authentication.: https://googleapis.github.io/google-cloud-python/latest/core/auth.html

Installation
~~~~~~~~~~~~

Install this library in a `virtualenv`_ using pip. `virtualenv`_ is a tool to
create isolated Python environments. The basic problem it addresses is one of
dependencies and versions, and indirectly permissions.

With `virtualenv`_, it's possible to install this library without needing system
install permissions, and without clashing with the installed system
dependencies.

Using the API
-------------

.. code:: python

    from google.cloud import logging_v2

    client = logging_v2.LoggingServiceV2Client()
    entries = []
    response = client.write_log_entries(entries)

    logger.log_text('A simple entry')  # API call

Example of fetching entries:

.. code:: python

    from google.cloud import logging
    client = logging.Client()
    logger = client.logger('log_name')
    for entry in logger.list_entries():
        print(entry.payload)
