JProfiler：幫助在步驟指南集成遠程服務器上的jprofiler ubuntu

Question

我想在ubuntu上配置一個運行tomcat7的遠程服務器。我已經閱讀了多個教程，但無法運行它。遠程服務器

首先我上

JProfiler的一體化遠程系統上下載jprofiler9和提取。

wget http://download-keycdn.ej-technologies.com/jprofiler/jprofiler_linux_9_2.tar.gz 
tar -xzf jprofiler_linux_9_2.tar.gz 

就跑以下命令

jprofiler9/bin# ./jpintegrate 

它問我一些信息，並生成2個文件

1. startup-jp.sh這個文件我想從startup.sh創建，如上面的嚮導要求我提供啓動腳本的路徑（/usr/share/tomcat7/bin/startup.sh），以便在同一個文件夾中創建新文件。
2. 配置，jp.xml同樣嚮導要求我輸入一些指令的配置文件的名稱：可以在 JProfiler的GUI進口快速連接到應用服務器

的變更內容是startup-jp.sh如下

# The following lines have been added by the 
# application server integration wizard of JProfiler 

CATALINA_OPTS="-agentpath:/home/ubuntu/jprofiler9/bin/linux-x64/libjprofilerti.so=port=8383 $CATALINA_OPTS" 
export CATALINA_OPTS 

# end of modifications 

exec "$PRGDIR"/"$EXECUTABLE" run "$@" 

Statring的JProfiler 這裏我很困惑如何運行的JProfiler，我想運行startup-jp.sh開始日Ë探查

它運行startup-jp.sh

後控制檯登錄成功，但是當我從我的本地系統的JProfiler GUI連接到該遠程服務器，服務器genrates沒有發現關於路徑一些錯誤

這裏運行

顯然它無法看到所需的不同目錄（怪），請注意，我從來沒有遇到startup.sh開始我tomcat7但使用service tomcat7 start，可能是這裏的問題。這裏是我的tomcat7目錄結構

在/ usr /共享/ tomcat7/

drwxr-xr-x 2 root root 4.0K Oct 28 04:21 bin 
-rw-r--r-- 1 root root 39 Feb 21 2014 defaults.md5sum 
-rw-r--r-- 1 root root 2.0K Feb 21 2014 defaults.template 
drwxr-xr-x 2 root root 4.0K Oct 10 06:06 lib 
-rw-r--r-- 1 root root 53 Feb 21 2014 logrotate.md5sum 
-rw-r--r-- 1 root root 118 Feb 21 2014 logrotate.template 

的/ var/lib中/ tomcat7/

drwxr-xr-x 3 tomcat7 tomcat7 4.0K Apr 21 2016 common 
lrwxrwxrwx 1 root root  12 Jun 19 2015 conf -> /etc/tomcat7

lrwxrwxrwx 1 root root  19 Jun 19 2015 work -> ../../cache/tomcat7 

通過增加固定例外以上在啓動-JP中的以下行。SH

export CATALINA_BASE="/var/lib/tomcat7/" 

現在能夠找到丟失的文件夾

新問題

現在的問題是我的本地JProfiler的GUI正在採取太多的時間（例如，如果我重新啓動腳本，它捕獲很少的條目，但不久後

tomcat的CPU使用率爲197.5％，受頂級命令的支配

因此沒有其他東西被本地jprofiler GUI加載。我無法找出造成這麼多CPU使用率的原因。

PID USER  PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 
5496 tomcat 38 18 3005m 675m 17m S 197.5 9.0 21:09.55 java 

Answer 1

該集成已正確完成，並按預期工作。

根據你的文件系統的權限，則必須執行startup-jp.sh爲根，所以執行

sudo sh startup-jp.sh
