为什么spring cloud gateway获取ServerStats都是初始值，没有实际指标？

Question

问题遇到的现象和发生背景

spring cloud gateway 获取服务实例运行的状态，都是0

用代码块功能插入代码，请勿粘贴截图

ServerStats serverStats = loadBalancerStats.getSingleServerStat(server);

运行结果及报错内容

[Server:192.168.101.182:8085; Zone:UNKNOWN; Total Requests:0; Successive connection failure:0; Total blackout seconds:0; Last connection made:Thu Jan 01 08:00:00 CST 1970; First connection made: Thu Jan 01 08:00:00 CST 1970; Active Connections:0; total failure count in last (1000) msecs:0; average resp time:0.0; 90 percentile resp time:0.0; 95 percentile resp time:0.0; min resp time:0.0; max resp time:0.0; stddev resp time:0.0]

我的解答思路和尝试过的方法

麻烦帮我看看为什么统计的指标都是初始值，没有实际的值呢。
