For example, the consul input will generate metric like:

consul_health_checks,node=consul01,service_name=,check_id=serfHealth,host=consul01 check_name="Serf Health Status",service_id="",status="passing" 1491927292000000000

Please note that those kvs like "check_name/service_id/status" will failed to send to openTSDB because it doesn't support string values....
