downstream_cx_protocol_error	Counter	Total protocol errors
downstream_cx_rx_bytes_buffered	Gauge	Total received bytes currently buffered
downstream_cx_rx_bytes_total	Counter	Total bytes received
downstream_cx_total	Counter	Total connections
downstream_cx_tx_bytes_buffered	Gauge	Total sent bytes currently buffered
downstream_cx_tx_bytes_total	Counter	Total bytes sent
downstream_cx_drain_close	Counter	Number of connections closed due to draining
downstream_rq_active	Gauge	Total active requests
downstream_rq_total	Counter	Total requests
