一个开源的多协议分布式负载测试工具，使用 erlang 语言开发的。
它能用来压力测试 HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP 和 Jabber/XMPP 的服务器。它可以分布在多个客户机，并能够模拟成千上万的虚拟用户数并发。 来自百度。。
我是在本机安装的虚拟机 CentOS7.1 系统，ejabberd 服务也在此虚拟机上安装好了，ejabberd 服务已启动，测试服务没有问题
然后安装 tsung1.5.1 等等软件之后，执行了一个注册用户的测试脚本，脚本设置的场景是注册 200 用户，运行结果只成功注册了一个用户。求大神帮忙看看问题在哪，脚本是按照官方给的例子修改的。
