Windows客戶端的JProfiler遠端監控Linux上的Tomcat伺服器

1.測試環境
伺服器：Redhat Enterprise Linux（核心版本 2.6.32-71.el6.i686 ），Tomcat6.0.16，Sun JDK 1.6，JProfiler 5.2.4 for linux（安裝包：jprofiler_linux_5_2_4.sh）
客戶端：Windows XP，JProfiler5.2.4 for windows（安裝包：jprofiler_windows_5_2_4.exe）

2.JProfiler軟體下載地址 http://www.ej-technologies.com/

3.客戶端 JProfiler 安裝（lincense key在附件中可以看到）

4.伺服器端 JProfiler 安裝：
把 jprofiler_linux_5_2_4.sh 上傳到到伺服器，假設路徑為 /usr/file/jprofiler_linux_5_2_4.sh

# cd /usr/file

# chmod 777 *.sh
# ./jprofiler_linux_5.1.2.sh -c
按照提示來安裝，提示都很簡單，不在多說。安裝路徑選擇 /opt/jprofiler5

注意，這裡的 -c 意思是用字元方式來安裝，如果機器上沒有 X 則加上該引數.

5.客戶端連線配置
1). 執行 JProfiler 。第一次開啟會有嚮導，忽略它。
2). 選擇 Session->Integration Wizard->New Remote Integratation
3). 選擇 On a remote computer；Platform of remote computer 選擇 Linux x86/AMD 64；Next
4). 輸入伺服器 IP ；Next
5). 輸入伺服器上的 jprofiler 的安裝路徑，如 /opt/jprofiler5 ；next
6). 選擇伺服器的 JDK 環境，這裡是：Sun，1.6.0，hotspot；next
7). 輸入埠：這裡是預設值 8849；next
8). 選擇啟動模式：這裡選第一種 wait for a connection from the jprofiler GUI；next
9). 這裡會列出需要在伺服器端做的配置:
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 192.168.1.105 will be created that connects to a running instance of the remote application that is started with the modified start command.

6.伺服器端的配置
(1)修改系統環境配置檔案 /etc/profile ,增加
JPROFILER_HOME=/opt/jprofiler5/bin/linux-x86
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JPROFILER_HOME


(2)修改TOMCAT啟動檔案catalina.sh，新增-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler5/bin/agent.jar 內容到CATALINA_OPTS中；
“-agentlib:jprofilerti=port=8849 -Xbootclasspath/a:/opt/jprofiler4/bin/agent.jar ” 此內容由客戶端軟體生成
CATALINA_OPTS="$CATALINA_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.啟動客戶端軟體
   點選jprofiler選單 session>start center>Open Session
   Available session configurations中列出了剛才配置的連線，選中使用就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.當中斷JProfiler連線時
   The log of tomcat which is $CATALINA_HOME/logs/catalina.out will show:
JProfiler> Disconnected. Waiting for reconnection.
JProfiler> Listening on port: 8849.
