LoadRunner监控Tomcat的几种方法

 
阅读更多

通过JConsole监控Tomcat

1、打开tomcat5bin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”。

使用SiteScope监控Tomcat

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TomcatJMX 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LRController中连接SiteScopeTomcat进行监控。
