windows客户端远程监控linux上的tomcat

  Windows客户端的JProfiler远程监控Linux上的Tomcatro
1.测试环境
服务器：ubuntu8.04（内核版本 2.6.24-16），Tomcat6.0.16，Sun JDK 1.6，JProfiler 5.1.2for linux（安装包：jprofiler_linux_5.1.2.sh）
客户端：Windows XP，JProfiler5.1.2 for windows（安装包：jprofiler_windows_5_1_2.exe）

2.JProfiler软件下载地址 http://www.ej-technologies.com/

3.客户端 JProfiler 安装 略

4.服务器端 JProfiler 安装：
把 jprofiler_linux_5.1.2.sh 上传到到服务器，假设路径为 /opt/jprofiler

# cd /opt/jprofiler
# chmod +x *.sh
# ./jprofiler_linux_5.1.2.sh -c
按照提示来安装，提示都很简单，不在多说。安装路径选择 /opt/jprofiler5

注意，这里的 -c 意思是用字符方式来安装，如果机器上没有 X 则加上该参数.

5.客户端连接配置
1). 运行 JProfiler 。第一次打开会有向导，忽略它。
2). 选择 Session->Integration Wizard->New Remote Integratation
3). 选择 On a remote computer；Platform of remote computer 选择 Linux x86/AMD 64；Next
4). 输入服务器 IP ；Next
5). 输入服务器上的 jprofiler 的安装路径，如 /opt/jprofiler5 ；next
6). 选择服务器的 JDK 环境，这里是：Sun，1.6.0，hotspot；next
7). 输入端口：这里是默认值 8849；next
8). 选择启动模式：这里选第一种 wait for a connection from the jprofiler GUI；next
9). 这里会列出需要在服务器端做的配置:
Integration type: [Generic application]
Selected JVM: Sun 1.6.0 (hotspot)
Startup mode: Wait for JProfiler GUI

(1) Please insert
-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler5/bin/agent.jar

into the start command of your remote application right after the java command.

(2) Please add
/opt/jprofiler5/bin/linux-x86

to the environment variable LD_LIBRARY_PATH.

A remote session named Remote application on 192.168.1.210 will be created that connects to a running instance of the remote application that is started with the modified start command.

6.服务器端的配置
(1)修改系统环境配置文件 /etc/profile ,增加
JPROFILER_HOME=/opt/jprofiler5/bin/linux-x86
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JPROFILER_HOME


(2)修改TOMCAT启动文件catalina.sh，添加-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler5/bin/agent.jar 内容到CATALINA_OPTS中；
“-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar ” 此内容由客户端软件生成
CATALINA_OPTS="$JPDA_OPTS -agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar"

7.Reboot Linux and startup Tomcat using startup.sh;
   The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Protocol version 23
JProfiler> Using JVMTI
JProfiler> 32-bit library
JProfiler> Listening on port: 8849.
JProfiler> Native library initialized
JProfiler> Waiting for a connection from the JProfiler GUI



8.启动客户端软件
   点击jprofiler菜单 session>start center>Open Session
   Available session configurations中列出了刚才配置的连接，选中使用就OK了！！

9.The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Using dynamic instrumentation
JProfiler> Time measurement: elapsed time
JProfiler> CPU profiling enabled
JProfiler> Hotspot compiler enabled
JProfiler> Starting org/apache/catalina/startup/Bootstrap

10.当中断JProfiler连接时
   The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Disconnected. Waiting for reconnection.
JProfiler> Listening on port: 8849.
