使用httperf和autobench直观的分析服务器性能
httperf + autobench + gnuplot安装
需要安装如下源码包：
autobench-2.1.2.tar.gz
gd-2.0.34.tar.bz2
gnuplot-4.2.0.tar.gz
httperf-0.9.0.tar.gz
pcre-7.1.tar.bz2
pcre-devel-4.5-3.2.RHEL4.i386.rpm
安装前先确认是否安装过如下程序：
gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel
libpng-devel libtiff-devel freetype-devel pam-devel pcre pcre-devel
安装GD2：
cd /usr/local/src
wget http://www.boutell.com/gd/http/gd-2.0.33.tar.gz
tar xzvf gd-2.0.33.tar.gz
cd gd-2.0.33
./configure --prefix=/usr/local/gd2
make
make install
echo "//usr/local/gd2/lib" >> /etc/ld.so.conf
ldconfig
安装texinfo-4.7：
cd /usr/local/src
wget http://ftp.gnu.org/gnu/texinfo/texinfo-4.8.tar.gz
tar zxvf texinfo-4.8.tar.gz
cd texinfo-4.8
./configure
make && make install
安装gnuplot：
cd /usr/local/src
wget http://nchc.dl.sourceforge.net/sourceforge/gnuplot/gnuplot-4.2.0.tar.gz
tar zxvf gnuplot-4.2.0.tar.gz
cd gnupolt-4.2.0
./configure \
--prefix=/usr/local/gnuplot \
--with-cwdrc --without-row-help \
--with-kpsexpand \
--with-gd=/usr/local/gd2
make && make install
安装httperf:
cd /usr/local/src
wget
tar zxvf httperf-0.8.tar.gz
cd httperf-0.8
./configure --prefix=/usr/local/httperf
make && make install
安装autobench包：
cd /usr/local/src
wget http://www.xenoclast.org/autobench/downloads/autobench-2.1.2.tar.gz
tar zxvf autobench-2.1.2.tar.gz
cd autobench-2.1.2
make && make install
vi /etc/profile
在HISTSIZE=1000下面添加一行：
export PATH=/usr/local/bin:/usr/local/gnuplot/bin:/usr/local/httperf/bin:$PATH
source /etc/profile
如果上面编译都没有错误，执行下面命令：
cp /usr/local/bin/bench2graph /usr/local/bin/bench2png
vi /usr/local/bin/bench2png
sed -i 's/postscript color/png xffffff/g' /usr/local/bin/bench2png
测试一个服务器性能，生成tsv文件：
/usr/local/bin/autobench \
--single_host \
--host1=192.168.0.2 \
--port1=80 \
--quiet \
--low_rate=10 \
--high_rate=100 \
--rate_step=10 \
--num_call=1 \
--num_conn=100 \
--timeout=10 \
--file /opt/result.tsv
把tsv文件用图形表示出来：
/usr/local/bin/bench2png /opt/result.tsv /opt/result.png [ 1 2 3 .... ]
如果对两台服务器进行比较，则用下面命令：
/usr/local/bin/autobench \
--host1=squid.yhc.com \
--port1=80 \
--host2=nginx.yhc.com \
--port2=80 \
--quiet \
--low_rate=100 \
--high_rate=5000 \
--rate_step=10 \
--num_call=1 \
--num_conn=3000 \
--timeout=5 \
--file /opt/result.tsv
再把生成的数据转化成图形：
/usr/local/bin/bench2png /opt/result.tsv /opt/result.png [ 1 2 3 .... ]
注：
[1 2 3 .... ]的值分别表示如下：
1 dem_req_rate
2 req_rate_nginx.yhc.com
3 con_rate_nginx.yhc.com
4 min_rep_rate_nginx.jackbillow.com
5 avg_rep_rate_nginx.jackbillow.com
6 max_rep_rate_nginx.jackbillow.com
7 stddev_rep_rate_yhc.jackbillow.com
8 resp_time_nginx.jackbillow.com
9 net_io_nginx.jackbillow.com
10 errors_nginx.jackbillow.com
11 req_rate_apache.jackbillow.com
12con_rate_apache.jackbillow.com
13 min_rep_rate_squid.jackbillow.com
14 avg_rep_rate_squid.jackbillow.com
15 max_rep_rate_squid.jackbillow.com
16 stddev_rep_rate_squid.jackbillow.com
17 resp_time_squid.jackbillow.com
18 net_io_squid.jackbillow.com
19 errors_squid.jackbillow.com
例如，我做如下对比：
2 req_rate_nginx.jackbillow.com
11 req_rate_squid.jackbillow.com
/usr/local/bin/bench2png /opt/result.tsv /opt/result.png [ 2 11 ]
3 con_rate_nginx.jackbillow.com
12 con_rate_squid.jackbillow.com
/usr/local/bin/bench2png /opt/result.tsv /opt/result.png [ 3 12 ]
4 min_rep_rate_nginx.jackbillow.com
13 min_rep_rate_squid.jackbillow.com
/usr/local/bin/bench2png /opt/Result.tsv /opt/result.png [ 4 13 ]
5 avg_rep_rate_nginx.jackbillow.com
14 avg_rep_rate_squid.jackbillow.com
/usr/local/bin/bench2png /opt/resultdef.tsv /opt/resulta5_14.png [ 5 14 ]
6 max_rep_rate_nginx.jackbillow.com
15 max_rep_rate_squid.jackbillow.com
/usr/local/bin/bench2png /opt/Resultabc.tsv /opt/resultaabc6_15.png [ 6 15 ]
7 stddev_rep_rate_nginx.jackbillow.com
16 stddev_rep_rate_squid.jackbillow.com
/usr/local/bin/bench2png /opt/Resultabc.tsv /opt/resultaabc7_16.png [ 7 16 ]
8 resp_time_nginx.jackbillow.com
17 resp_time_squid.jackbillow.com
/usr/local/bin/bench2png /opt/resultdef.tsv /opt/resultaabc8_17.png [ 8 17 ]
9 net_io_nginx.jackbillow.com
18 net_io_squid.jackbillow.com
/usr/local/bin/bench2png /opt/resultdef.tsv /opt/resultaabc9_18.png [ 9 18 ]
10 errors_nginx.jackbillow.com
19 errors_squid.jackbillow.com
/usr/local/bin/bench2png /opt/Resultabc.tsv /opt/resultaabc10_19.png [ 10 19 ]
