Overview
========

``monasca-api`` is a RESTful API server that is designed with a `layered
architecture`_.

Documentation
-------------

The full API Specification can be found in `docs/monasca-api-spec.md`_

Python Monasca API Implementation
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To install the python api implementation, git clone the source and run
the following command:

::

   $ sudo python setup.py install

If it installs successfully, you will need to make changes to the
following two files to reflect your system settings, especially where
kafka server is located:

::

   /etc/monasca/api-config.ini
   /etc/monasca/monasca-api.conf
   /etc/monasca/api-logging.conf

Once the configuration files are modified to match your environment, you
can start up the server by following the following instructions.

To start the server, run the following command:

::

   Running the server in foreground mode
   $ gunicorn -k eventlet --worker-connections=2000 --backlog=1000 --paste /etc/monasca/api-config.ini

   Running the server as daemons
   $ gunicorn -k eventlet --worker-connections=2000 --backlog=1000 --paste /etc/monasca/api-config.ini -D

To check if the code follows python coding style, run the following
command from the root directory of this project

::

   $ tox -e pep8

To run all the unit test cases, run the following command from the root
directory of this project

::

   $ tox -e py36

Start the Server - for Apache
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To start the server using Apache: create a modwsgi file, create a
modwsgi configuration file, and enable the wsgi module in Apache.

The modwsgi configuration file may look something like this, and the
site will need to be enabled:

.. code:: apache

       Listen 8070

       <VirtualHost *:8070>

           WSGIDaemonProcess monasca-api processes=4 threads=1 socket-timeout=120 user=mon-api group=monasca python-path=/usr/local/lib/python2.7/site-packages
           WSGIProcessGroup monasca-api
           WSGIApplicationGroup monasca-api
           WSGIScriptAlias / /usr/local/lib/python2.7/site-packages/monasca_api/api/wsgi/monasca_api.py

           WSGIPassAuthorization On

           LogLevel info
           ErrorLog /var/log/monasca-api/wsgi.log
           CustomLog /var/log/monasca-api/wsgi-access.log combined

           <Directory /usr/local/lib/python2.7/site-packages/monasca_api>
             Require all granted
           </Directory>

           SetEnv no-gzip 1

       </VirtualHost>

The wsgi file may look something like this:

.. code:: py


       from monasca_api.api import server

       application = server.get_wsgi_app(config_base_path='/etc/monasca')

WARNING: The Java implementation of Monasca API is DEPRECATED and will
be removed in future release.
