Class to serve Ceilometer API with apache mod_wsgi in place of ceilometer-api service.

Serving Ceilometer API from apache is the recommended way to go for production systems as the current keystone implementation is not multi-processor aware, thus limiting the performance for concurrent accesses.

When using this class you should disable your ceilometer-api service.

Parameters

[*servername*]
  The servername for the virtualhost.
  Optional. Defaults to $::fqdn

[*port*]
  The port.
  Optional. Defaults to 8777

[*bind_host*]
  The host/ip address Apache will listen on.
  Optional. Defaults to undef (listen on all ip addresses).

[*path*]
  The prefix for the endpoint.
  Optional. Defaults to '/'

[*ssl*]
  Use ssl ? (boolean)
  Optional. Defaults to true

[*workers*]
  Number of WSGI workers to spawn.
  Optional. Defaults to 1

[*priority*]
  (optional) The priority for the vhost.
  Defaults to '10'

[*threads*]
  (optional) The number of threads for the vhost.
  Defaults to $::processorcount

[*ssl_cert*]
[*ssl_key*]
[*ssl_chain*]
[*ssl_ca*]
[*ssl_crl_path*]
[*ssl_crl*]
[*ssl_certs_dir*]
  apache::vhost ssl parameters.
  Optional. Default to apache::vhost 'ssl_*' defaults.
