Blueflood StatsD Backend

This is a statsD backend that will send metrics aggregated in statsD to an instance of Blueflood.

Blueflood Configuration

The Blueflood statsD endpoint is new and has experimental status.
See blueflood/pull/201.

Assumed endpoint is http://host:port/v1.0/:tenantId/experimental/metrics/statsd.

StatsD Configuration

Your statsD configuration file will need a blueflood section similar to the way you would have one for graphite or the console if you were using those backends.

Here are the values that are currently honored:

• tenantId: (required) This tenantId will be used to publish metrics to Blueflood.
• endpoint: (required) The location of the API. e.g.: 'http://metrics.example.com:8080'

Example configuration:

"blueflood": {
  "tenantId": "333333",
  "endpoint": "http://127.0.0.1:19000"
},

You can also send metrics into the Rackspace Cloud Metrics API service by adding the follwing auth section to the configuration:

"blueflood": {
  "tenantId": "333333",
  "endpoint": "http://iad.metrics-ingest.api.rackspacecloud.com:80",
  "authModule": "./auth",
  "authClass": "RaxAuth",
  "authParams": {
    "raxusername": "my_cloud_user_name",
    "raxapikey": "my_rax_api_key"
  }
}

If you happen to use some other Openstack identity service, or even something home-grown, you can create your own authenticator, just make sure to implement the methods indicated by auth.EmptyAuth.
