VM间记录时延

记录时延采用Ping和SockPerf，分别采用下面的Bash命令记录到相关的文件中：

ping 10.2.1.5 -i 15 | while read pong; do echo "$(date): $pong" >> ping.txt; done &

while true; \
  do sockperf ping-pong \
  -i 10.2.1.5 -p 80 --tcp \
  --full-rtt -m 64 | awk '{print $0 " --- " strftime()}' >> sock.txt; \
  sleep 60; \
done &

对于获取到的文件，可以采用下面的脚本统计相关的数据：

#!/bin/bash

a=$(cat $1 | wc -l)
echo Total $a
a=$(cat $1 | awk -F 'ms' '{print $1}' | awk -F '=' '$4 >= 5' | wc -l)
echo bigger_5ms $a
a=$(cat $1 | awk -F 'ms' '{print $1}' | awk -F '=' '$4 < 5 ' | awk -F '=' '$4 >= 4' | wc -l)
echo between_4ms-5ms $a
a=$(cat $1 | awk -F 'ms' '{print $1}' | awk -F '=' '$4 < 4 ' | awk -F '=' '$4 >= 3' | wc -l)

a=$(cat $1 | awk -F 'ms' '{print $1}' | awk -F '=' '$4 <0.8 ' | awk -F '=' '$4 >= 0.7' | wc -l)
echo between_0.7ms-0.8ms $a
a=$(cat $1 | awk -F 'ms' '{print $1}' | awk -F '=' '$4 <0.7 ' | awk -F '=' '$4 >= 0.6' | wc -l)
echo between_0.6ms-0.7ms $a

通过命令result.sh ping.txt sock.txt实现数据的统计。
