Prometheus Node Exporter - CPU and Memory Usage

CPU Usage :

(1 - avg(irate(node_cpu_seconds_total{mode="idle"}[10m])) by (instance)) * 100

Memory Usage :

100 * (1 - ((avg_over_time(node_memory_MemFree_bytes[10m]) + avg_over_time(node_memory_Cached_bytes[10m]) + avg_over_time(node_memory_Buffers_bytes[10m])) / avg_over_time(node_memory_MemTotal_bytes[10m])))

如何找出 TCP 连接建立时间与最后一次通讯时间

这个问题是在《形单影只的 Socket》最后留的问题,这里给出一个思路供大家参考,看下那篇文章再来看这个效果可能会更好。

传送门: 测试环境:Ubuntu 14.04 好了,进入正题。首先构造一个 TCP 连接,这里使用形单影只的 socket 来启动一个 echo server

$ nc -vp 11111 localhost 11111
Connection to localhost 11111 port [tcp/*] succeeded!

$ ss -ap | grep 11111
