第十章实战部分疑惑:
<1> 暴露metrics之后,无法通过http://localhost:8080/actuator/metrics或者http://localhost:8080/actuator/prometheus访问到监控的数据
<2> JMX提供的暴露的数据太有限了,有点鸡肋,监控的数据太少了
<3> 使用prometheus-stack采集,但是看源码,监控指标比micrometer少的太多了,那么它存在的意义是什么的,那还不如直接用micrometer,然后通过工具转化成prometheus
不知道我理解对不对,帮忙指点一二,thks
作者在1.2.5中TCP参数调优中提到,可以开启tcp_tw_reuse选项,重用time-wait的连接,但是最后部署到线上没有效果,但是作者没有解释是什么原因,所以想具体请教一下。
