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 the monitoring api.`_
3. `Setup Authentication.`_

.. _Select or create a Cloud Platform project.: https://console.cloud.google.com/project
.. _Enable the trace api.:  https://cloud.google.com/trace
.. _Setup Authentication.: https://googlecloudplatform.github.io/google-cloud-python/latest/google-cloud-auth

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.

TraceServiceClient
^^^^^^^^^^^^^^^^^^^^^^

.. code:: py

  from google.cloud.gapic.trace.v1 import trace_service_client
  from google.gax import CallOptions, INITIAL_PAGE
  client = trace_service_client.TraceServiceClient()
  project_id = ''

  # Iterate over all results
  for element in client.list_traces(project_id):
      # process element
      pass

  # Or iterate over results one page at a time
  for page in client.list_traces(project_id, options=CallOptions(page_token=INITIAL_PAGE)):
      for element in page:
          # process element
          pass
