LoadRunner監控Tomcat的幾種方法(轉自csdn,陳能技ID：Testing_is_believing)

通過JConsole監控Tomcat

1、打開tomcat5的bin目錄中的catalina.bat文件，在頭部注釋部分的后面加上：

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遠程訪問授權。

進入JAVA安裝目錄的"jre6"lib"management目錄，把jmxremote.password.template文件改名為jmxremote.password，去掉最后兩行的注釋（用戶名和密碼）：

monitorRole QED

controlRole R&D

確保jmxremote.access文件末尾的訪問角色沒有被注釋掉：

monitorRole readonly

controlRole readwrite "

create javax.management.monitor.*,javax.management.timer.* "

unregister

然后分別選擇這兩個文件，點右鍵“屬性”-〉安全，點“高級”，去掉“從父項繼承....”，彈出窗口中選“刪除”，這樣刪除了所有訪問權限。再選“添加”-〉高級，“立即查找”，選中你的用戶，例administrator，點“確定"，“確定"。來到權限窗口，勾選"完全控制"，點"確定"

注：JDK好像需要裝在NTFS文件系統下才行

3、啟動Tomcat

4、在命令行輸入netstat -an 查看端口8999是否已經打開，如果沒有，則是前面的配置沒配好。

5、如果已經配置好，則在命令行輸入jconsole，打開jdk自帶的JMX客戶端，選擇遠程連接，錄入tomcat所在機器的IP，端口例192.168.1.100:8999，帳號、密碼在jmxremote.password中，如帳號controlRole，密碼R&D（缺省monitorRole只能讀，controlRole能讀寫，jmxremote.access中可配置）。點“連接”。
