我运行TSung的机器装的是Ubuntu 10.04 Server amd64。以下是从安装Tsung到使用Tsung对Openfire进行压力测试的步骤。
1. 下载并安装Tsung.
//安装Erlang及相关组件(必装) apt-get install erlang erlang-nox erlang-dev erlang-parsetools //安装生成报表必须的软件 apt-get install perl5 gnuplot libtemplate-perl //下载Tsung的deb包 wget http://tsung.erlang-projects.org/dist/ubuntu/lucid/tsung_1.4.1-1_all.deb //安装Tsung dpkg -i tsung_1.4.1-1_all.deb
2. 配置Tsung
~/.tsung/tsung.xml为tsung默认的配置文件,但我们安装后会发现这个目录和文件并不存在,那就由我们手动来创建这个目录。
mkdir ~/.tsung
在/usr/share/doc/tsung/examples/中有一些示例文件,可以参考jabber_register.xml文件来编写自己的tsung.xml。
cp /usr/share/doc/tsung/examples/jabber_register.xml ~/.tsung/tsung.xml
打开这个文件看一下,做一些修改。

配置文件中确定好server的host和port,通过<users maxnumber…>来设置要注册的最大用户数即可。
3. 启动Tsung
tsung start/stop/debug/status
运行中,可从openfire的界面上看到不断增加的用户。
4. 生成报表
//进入日志目录 cd ~/.tsung/log/20120728-0511 //运行脚本生成报表文件 /usr/lib/tsung/bin/tsung_stats.pl
5. 查看生成的报表
//安装apache2 apt-get install apache2 //建立符号链接 cd /var/www ln -s ~/.tsung/log/ tsungreport
这是就可以访问:http://localhost/tsungreport/20120728-0511/report.html来访问报表了。
