这是一个压力测试工具，可以测试包括HTTP, WebDAV, PostgreSQL, MySQL, LDAP, and XMPP/Jabber等服务器。针对 HTTP 测试，Tsung 支持 HTTP 1.0/1.1 ，包含一个代理模式的会话记录、支持 GET、POST 和 PUT 以及 DELETE 方法，支持 Cookie 和基本的 WWW 认证，同时还支持 SSL。
Tsung is an open-source multi-protocol distributed load testing tool
It can be used to stress HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and Jabber/XMPP servers. Tsung is a free software released under the GPLv2 license.
The purpose of Tsung is to simulate users in order to test the scalability and performance of IP based client/server applications. You can use it to do load and stress testing of your servers. Many protocols have been implemented and tested, and it can be easily extended.
It can be distributed on several client machines and is able to simulate hundreds of thousands of virtual users concurrently (or even millions if you have enough hardware ...).
Tsung is developed in Erlang, an open-source language made by Ericsson for building robust fault-tolerant distributed applications.
Features
High Performance: the load can be distributed on a cluster of client machines
Multi-protocols using a plugin system: HTTP, WebDAV, SOAP, PostgreSQL, MySQL, LDAP and XMPP/Jabber are currently supported. SSL is also supported.
Several IP addresses can be used on a single machine using the underlying OS IP Aliasing
OS monitoring (CPU, memory and network traffic) using SNMP, Munin or Erlang agents on remote servers.
XML configuration system; several sessions can be used to simulate different type of users. Dynamic sessions can be easily described in XML (this can be used to retrieve at runtime an ID from the server output and use it later in the session).
In order to generate a realistic traffic, user think-times and the arrival rate can be randomize using a probability distribution
HTML reports can be generated during the load to view response times measurement, server CPU, etc.
