     The ID of a specific Circonus Broker to use when creating a new check. The numeric portion of `broker._cid` field in a Broker API object. If metric management is enabled and neither a Submission URL nor Check ID is provided, an attempt will be made to search for an existing check using Instance ID and Search Tag. If one is not found, a new HTTPTRAP check will be created. By default, this is not used and a random Enterprise Broker is selected, or the default Circonus Public Broker.

     A special tag which will be used to select a Circonus Broker when a Broker ID is not provided. The best use of this is to as a hint for which broker should be used based on *where* this particular instance is running (e.g. a specific geo location or datacenter, dc:sfo). By default, this is left blank and not used.
