tomcat监控工具psi-probe

一、简介

psi-probe是lambdaprobe的一个分支版本，用于对Tomcat进行监控，比tomcat的manager强大很多。

psi就是一个形如叉子的符号Ψ，希腊字母的第23个字母，用来代表fork。

为啥需要分支呢，因为lambdaprobe已经多年没有更新（大致在2006年就停止发布新版本了）。

二、下载地址

http://code.google.com/p/psi-probe/downloads/list

三、安装

1.解压，将probe.war放进webapps目录。

2.修改CATALINA_HOME/conf/tomcat-users.xml

（权限配置参考如下，由于首先保证可运行，权限没有特别细分，仅供参考）

<tomcat-users>
