日志解析：

summary +是这三分钟的数据，

summary =是累计到当前时刻所有的数据

以第三行数据为例，5828是发出的请求数目，287s是时间， 20.3是每秒发出的请求，即吞吐量，

Avg, Min, Max分别是平均响应时间，最小响应时间和最大响应时间，响应时间指的是从请求发出到收到响应的时间，单位是ms，

Err后面跟的数据分别是错误数和错误比例。

对于summariser报告，可以通过写一个简单的脚本来解析并作图形化展示，下面是用Python写的一个简单脚本，可以画平均时延和吞吐量，使用方法是

import matplotlib.pyplot as plt
import re
import sys

avgtime_data=[]
mintime_data=[]
maxtime_data=[]
throughput_data=[]

logfile=open(sys.argv[1])
try:
    while True:
        line=logfile.readline()
        if line=='':
            break
        if line.startswith('summary ='):
            result=re.split(r'\s+', line)
            avgtime_data.append(result[8])
            throughput=result[6]
            throughputvalue=throughput[:-2]
            throughput_data.append(throughputvalue)
finally:
    logfile.close()

plt.figure(figsize=(8,4))
plt.ylim(0,60)
plt.plot(avgtime_data,color="red",label="Avg ResponseTime (milliseconds)")
plt.plot(throughput_data,color="green",label="ThroughPut (/s)")
frame = plt.gca()
frame.axes.xaxis.set_ticklabels([])
plt.xlabel("Duration, 2013/06/25 16:30:00 -- 2013/06/28 6:00:00, about 60 hours")
plt.title("sundong Jmeter Test Report")
plt.legend()
plt.show()

 

 

Jmeter在做性能测试的时候，可能会run很长时间，这样产生的log会非常大，跑过一次72小时的测试，log达到了6G！,

这样分析起来会比较麻烦，JMeter还提供了summariser result report，就是在每隔一段时间打一行log，这样log就会大大减小。

Jmeter summariser report的设置在：bin/jmeter.properties.

#---------------------------------------------------------------------------
# Summariser - Generate Summary Results - configuration (mainly applies to non-GUI mode)
#---------------------------------------------------------------------------
#
# Define the following property to automatically start a summariser with that name
# (applies to non-GUI mode only)
summariser.name=summary
#
# interval between summaries (in seconds) default 3 minutes
summariser.interval=180  //这个表示统计频率
#
# Write messages to log file
summariser.log=true
#
# Write messages to System.out
#summariser.out=true   //是否将统计结果输出到控制台

以上设置每隔3分钟向jmeter.log中写入一行log

# Combined log file (for jmeter and jorphan)
log_file=jmeter.log
