Gnocchi Formula
==================================

Service Gnocchi description

Gnocchi is an open-source time series database. The problem that Gnocchi solves
is the storage and indexing of time series data and resources at a large scale.
This is useful in modern cloud platforms which are not only huge but also are
dynamic and potentially multi-tenant. Gnocchi takes all of that into account.


Sample Pillars
==============

.. note::
   Before deploying gnocchi, Apache2 should be configured to serve wsgi vhost for Gnocchi API.
   Example of Apache pillar with Gnocchi site:

.. code-block:: yaml

    apache:
      server:
        enabled: true
        default_mpm: event
        mpm:
          prefork:
            enabled: true
            servers:
              start: 5
              spare:
                min: 2
                max: 10
            max_requests: 0
            max_clients: 20
            limit: 20
        site:
          gnocchi:
            enabled: false
            available: true
            type: wsgi
            name: gnocchi
            host:
              name: gnocchi.site.com
              address: 127.0.0.1
              port: 8041
            log:
              custom:
                format: >-
                  %v:%p %{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %D %O \"%{Referer}i\" \"%{User-Agent}i\"
            wsgi:
              daemon_process: gnocchi-api
              processes: ${_param:gnocchi_api_workers}
              threads: 10
              user: gnocchi
              group: gnocchi
              display_name: '%{GROUP}'
              script_alias: '/ /usr/bin/gnocchi-api'
              application_group: '%{GLOBAL}'
              authorization: 'On'
        pkgs:
          - apache2
        modules:
          - wsgi
