Metric Name	TYpe	Description
http_reqs	Counter	k6产生的总的请求数
http_req_blocked	Trend	等待空闲的TCP连接槽的等待时间
http_req_connecting	Trend	建立到远程主机的TCP连接所花费的时间
http_req_tls_handshaking	Trend	与远程主机握手TLS会话花费的时间
http_req_sending	Trend	发送数据到远程机的时间
http_req_waiting	Trend	等待远程主机所花费的时间
http_req_receiving	Trend	从远程主机接收响应数据所花费的时间
http_req_duration	Trend	请求的总时间= http_req_sending + http_req_waiting + http_req_receiving
