2022年LoadRunner监控Tomcat的几种方法 .pdf

LoadRunner监控 Tomcat的几种方法通过 JConsole监控 Tomcat1、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 jre6libmanagement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import java.lang.management.MemoryUsage;
