性能测试是软件测试中很重要的工程工程，有时候我们需要测试的一项内容便是 web 页面响应时间，httping 就是这样一种专门用来测试 web 页面响应时间的开源软件。
在 FreeBSD 下安装
#cd /usr/ports/net/httping
#make install clean
#rehash
用法如下
#httping -h
httping: option requires an argument — h
HTTPing v1.2.6, (C) 2003-2008 folkert@vanheusden.com
SSL support included
-g url url (e.g. -g http://localhost/)
-h hostname hostname (e.g. localhost)
-p portnr portnumber (e.g. 80)
-x host:port hostname+portnumber of proxyserver
-c count how many times to connect
-i interval delay between each connect
-t timeout timeout (default: 30s)
-s show statuscodes
-S split time in connect-time and processing time
-G do a GET request instead of HEAD (read the
contents of the page as well)
-b show transfer speed in KB/s (use with -G)
-B like -b but use compression if available
-L x limit the amount of data transferred (for -b)
to ‘x’ (in bytes)
-X show the number of KB transferred (for -b)
-l connect using SSL
-z show fingerprint (SSL)
-f flood connect (no delays)
-a audible ping
-m give machine parseable output (see
also -o and -e)
-o rc,rc,… what http results codes indicate ‘ok’
coma seperated WITHOUT spaces inbetween
default is 200, use with -e
-e str string to display when http result code
doesn’t match
-I str use ‘str’ for the UserAgent header
-R str use ‘str’ for the Referer header
-r resolve hostname only once (usefull when
pinging roundrobin DNS: also takes the first
DNS lookup out of the loop so that the first
measurement is also correct)
-n warn,crit Nagios-mode: return 1 when avg. response time
>= warn, 2 if >= crit, otherwhise return 0
-N x Nagios mode 2: return 0 when all fine, ‘x’
when anything failes
-y ip[:port] bind to ip-address (and thus interface) [/port]
-q quiet, only returncode
-V show the version
每一个选项都有注释 比较好懂
下面就用他来测试本地到 sina 的页面响应时间吧
由于网络延时 堵塞等原因 可能出现不稳定的结果
测试 10 次取平均值
#httping -c10 -g http://www.sina.com.cn

— http://www.sina.com.cn ping statistics —
10 connects, 10 ok, 0.00% failed
round-trip min/avg/max = 4.8/1625.8/6204.2 ms
平均值为 1625.8ms，也就是 1.63s
如果是测试本网段的某个主机，则测试结果就比较可以信任了
#httping -c10 -g http://www.linuxidc.com

— http://www.linuxidc.com ping statistics —
10 connects, 10 ok, 0.00% failed
round-trip min/avg/max = 17.1/29.8/107.0 ms
测试结果出来了
最小 web 页面响应时间：17.1 ms
平均 web 页面响应时间：29.8 ms
最大 web 页面响应时间：107.0 ms
一般来说 对我们有意义的数据是是平均值
可以用 shell 直接取到这个值得
#httping -c5 -g http://www.linuxidc.com | tail -n1 | awk ‘{print $4}’ | cut -d/ -f2
还可以配合 shell 和 rrdtool 可以画出一张完美的 web 响应时间图来，还不错，^_^^_^
