LoadRunner监控Tomcat的几种方法

通过JConsole监控Tomcat

1、打开tomcat5的bin目录中的catalina.bat文件，在头部注释部分的后面加上：

set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.port=8999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false 2、修改JMX远程访问授权。

进入JAVA安装目录的\jre6\lib\management目录，把jmxremote.password.template文件改名为jmxremote.password，去掉最后两行的注释（用户名和密码）： monitorRole QED controlRole R&D

确保jmxremote.access文件末尾的访问角色没有被注释掉： monitorRole readonly controlRole readwrite \

create javax.management.monitor.*,javax.management.timer.* \ unregister

然后分别选择这两个文件，点右键“属性”-〉安全，点“高级”，去掉“从父项继承....”，弹出窗口中选“删除”，这样删除了所有访问权限。再选“添加”-〉高级，“立即查找”，选中你的用户，例administrator，点“确定"，“确定"。来到权限窗口，勾选"完全控制"，点"确定" 注：JDK好像需要装在NTFS文件系统下才行 3、启动Tomcat

4、在命令行输入netstat -an 查看端口8999是否已经打开，如果没有，则是前面的配置没配好。 5、如果已经配置好，则在命令行输入jconsole，打开jdk自带的JMX客户端，选择远程连接，录入tomcat所在机器的IP，端口例192.168.1.100:8999，帐号、密码在jmxremote.password中，如帐号controlRole，密码R&D（缺省monitorRole只能读，controlRole能读写，jmxremote.access中可配置）。点“连接”。

编写JAVA程序收集Tomcat性能数据
