关于带宽命中率参考: Bandwidth and Transfer
proxy.node.bandwidth_hit_ratio
The difference of proxy.node.user_agent_total_bytes and proxy.node.origin_server_total_bytes, divided by proxy.node.user_agent_total_bytes.Represents the ratio of bytes served to user agents which were satisfied by cache hits, since statistics collection began.proxy.node.bandwidth_hit_ratio_avg_10s
The difference of proxy.node.user_agent_total_bytes_avg_10s and proxy.node.origin_server_total_bytes_avg_10s, divided by proxy.node.user_agent_total_bytes_avg_10s.Represents the ratio of bytes served to user agents which were satisfied by cache hits, over the previous 10 seconds.带宽命中率可由下面计算得来：
1 [root@~]# /opt/soft/ats/bin/traffic_ctl metric match total_bytes_avg_10s 2 proxy.node.user_agent_total_bytes_avg_10s 2161301760.000000 3 proxy.node.origin_server_total_bytes_avg_10s 176160640.000000 4 proxy.cluster.user_agent_total_bytes_avg_10s 1325454080.000000 5 proxy.cluster.origin_server_total_bytes_avg_10s 1294467072.000000 6 [root@~]# 7 [root@~]# /opt/soft/ats/bin/traffic_ctl metric get proxy.node.bandwidth_hit_ratio_avg_10s 8 proxy.node.bandwidth_hit_ratio_avg_10s 0.918493 9 [root@~]# 10 [root@~]# awk ‘BEGIN{print (2161301760-176160640)/2161301760}‘ 11 0.918493 12 [root@~]#
proxy.node.http.throughput10秒内的响应客户端的输出带宽值，单位是
bytes
1 proxy.node.http.throughput 2 Collection: global 3 Type: gauge 4 Units: bytes 5 Datatype: integer 6 The throughput of responses to user agents over the previous 10 seconds, in bytes.
proxy.node.client_throughput_out10秒内的响应客户端的输出带宽值，单位是
megabits
1 proxy.node.client_throughput_out 2 Collection: global 3 Type: gauge 4 Units: mbits 5 Datatype: float 6 The value of proxy.node.http.throughput represented in megabits.
Code：
1 integer ‘proxy.node.http.throughput‘ [[ 2 local self = ... 3 4 return rate_of_10s(self, 5 function() return proxy.node.http.user_agent_total_response_bytes end 6 ) 7 ]]
