Windows客户端的JProfiler远程监控Linux上的Tomcat

1.测试环境
服务器：RedHat Linux 3.4.3-9.EL4（内核版本 2.6.9-5.EL），Tomcat5.5.20，Sun JDK 1.5.0_09，JProfiler 4.3.2 for linux（安装包：jprofiler_linux_4_3_2.sh）
客户端：Windows XP，JProfiler 4.3.2 for windows（安装包：jprofiler_windows_4_3_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_4.3.2.sh 上传到到服务器，假设路径为 /opt/jprofiler

# cd /opt/jprofiler
# chmod +x *.sh
# ./jprofiler_linux_4.3.2.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/jprofiler4

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/jprofiler4 ；next
6). 选择服务器的 JDK 环境，这里是：Sun，1.5.0，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:

Integrationtype:[Genericapplication]
SelectedJVM:Sun1.5.0(hotspot)
Startupmode:WaitforJProfilerGUI

(1)Pleaseinsert

-agentlib:jprofilerti=port=8849-Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar

intothestartcommandofyourremoteapplicationrightafterthejavacommand.

(2)Pleaseadd

/opt/jprofiler4/bin/linux-x86

totheenvironmentvariableLD_LIBRARY_PATH.

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/jprofiler4/bin/linux-x86
exportLD_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/jprofiler4/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="$CATALINA_OPTS-Xms128m-Xmx128m$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>Protocolversion23
JProfiler>UsingJVMTI
JProfiler>32-bitlibrary
JProfiler>Listeningonport:8849.
JProfiler>Nativelibraryinitialized
JProfiler>WaitingforaconnectionfromtheJProfilerGUI

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>Usingdynamicinstrumentation
JProfiler>Timemeasurement:elapsedtime
JProfiler>CPUprofilingenabled
JProfiler>Hotspotcompilerenabled
JProfiler>Startingorg/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.Waitingforreconnection.
JProfiler>Listeningonport:8849.
