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

1、安装SiteScope
LR9.5的安装包中附带了SiteScope9.5的安装文件
\Additional Components\Sitescope\SiteScope 9.50
2、配置SiteScope
新建监视器，选择JMX类别
输入Tomcat的JMX URL地址，例如：
service:jmx:rmi:///jndi/rmi://192.168.1.100:8999/jmxrmi
用户名：monitorRole
密码：QED
添加计数器，例如：
java.lang/Memory/HeapMemoryUsage/used
java.lang/Memory/HeapMemoryUsage/max
Catalina/ThreadPool/jk-8010/currentThreadCount
Catalina/ThreadPool/jk-8010/maxSpareThreads
Catalina/ThreadPool/jk-8010/minSpareThreads
然后就可以在LR的Controller中连接SiteScope对Tomcat进行监控。
