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：

Python脚本：

#!/usr/bin/env python
import sys

b=[0]*12
m=[0]*12
s=[0]*12

f = open(str(sys.argv[1]), 'r')
n = 0

for i in f:
    if 'ms' in i:
        a = float(i.split("time=")[1].split()[0])
        if a>=10:
            t=a/10
            if t>10:
                b[10]=b[10]+1
            else:
                b[int(a/10)]=b[int(a/10)]+1
        elif a>=1:
            m[int(a)]=m[int(a)]+1
        else:
            s[int(a*10)]=s[int(a*10)]+1
f.close()

for i in range(1,10):
    print i*0.1,'ms -', (i+1)*0.1, 'ms  --- ', s[i]

for i in range(1,10):
    print i,'ms -', i+1, 'ms  --- ', m[i]

for i in range(1,10):
    print i*10,'ms -', (i+1)*10, 'ms  --- ', b[i]
print '>100ms --- ', b[10]

Bash脚本：

#!/bin/bash

a=$(cat $1 | wc -l)
echo Total $a

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 $a
a=$(cat $1 | awk -F 'ms' '{print $1}' | awk -F '=' '$4 <0.6 ' | wc -l)
echo smaller_0.6ms $a

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