Sensu RabbitMQ configuration

Issue

• For the Sensu client configuration settings, we currently have the following configuration for /usr/share/openstack-tripleo-heat-templates/environments/monitoring-environment.yaml:

parameter_defaults:
  MonitoringRabbitHost: 10.10.10.10
  MonitoringRabbitPort: 5672
  MonitoringRabbitUserName: sensu
  MonitoringRabbitPassword: sensu
  MonitoringRabbitUseSSL: false
  MonitoringRabbitVhost: "/sensu"
  SensuClientCustomConfig:
    api:
      warning: 10
      critical: 20

• However, we need to configure high-availability and we tested manually the following syntax inside /etc/sensu/conf.d/rabbitmq.json fil on sensu_client:

{
  "rabbitmq": [
   {
    "port": 5672,
    "host": "10.10.10.10",
    "user": "sensu",
    "password": "sensu",
    "vhost": "/sensu",
    "heartbeat": 30,
    "prefetch": 1
   },
   {
    "port": 5672,
    "host": "10.10.10.11",
    "user": "sensu",
    "password": "sensu",
    "vhost": "/sensu",
    "heartbeat": 30,
    "prefetch": 1
   }
  ]
}

• How can we configure this parameters on our template (monitoring-environment.yaml) to reflect the change mentioned above to the overcloud nodes?
