Jprofiler 10 License Key Free Dҽsignҽd for Java programmҽrs, JProfiler Portable is a rҽsourcҽful application that can bҽ usҽd to analyzҽ JVM tools, troublҽshoot possiblҽ bottlҽnҽcқs and rҽsolvҽ mҽmory lҽaқs. Execute the command line uutility bin/jpintegrate in the JProfiler distribution on the remote machine and select your application server and follow the subsequent steps. Then, proceed as in alternative A. This option is actually preferable to alternative A and unless you have to profile an already running JVM, you should take this route.
Non-profit open source projects with an established web site and a released product can apply for an open source project license for JProfiler in exchange for a link to

Preferably, the link should be a text link including the words 'Java profiler'. The link must not contain the 'nofollow' attribute. If you need an icon, please use one of these images:

We show 2 methods of installing JProfiler agent and accessing JVM to be profiled from remote location.
JProfiler is an award-winning all-in-one Java profiler and an alternative to jvisualvm. JProfiler's GUI helps you detect performance bottlenecks, memory leaks and resolve threading issues. New features in 7.1 include i.a. JPA/Hibernate probe supporting Hibernate 3.x/4.x, EclipseLink 2.3+ and OpenJPA 2.1+. It is not cheap - comparing to jvisualvm ;) but some of you may have access to it's license e.g. academic one or even qualify for open-source license.
As for remote access you will need a TCP port, login to Java Control Panel and on ‘Ports' page determine a port number you are sure is not in use - for example one labelled OPENEJB_ADMIN or ask support for new port assignment for JProfiler exclusively.
Download JProfiler to your home directory and unpack it e.g.
Some of you may prefer to download RPM or shell installer. File locations may differ in that case.
Method 1: Start JProfiler with jpenable
Easier method for Java 1.6 or higher (which is rather typical version these days) but has the drawback that array allocations are not recorded, it means stack trace information for array allocations is not available. If you are profiling frequently you may prefer method 2 though.
Download the same tarball to your linux PC (or correct one for you OS), unpack and run jprofiler from bin directory.
- Click Session > New Session
- Choose ‘Attach to profiled JVM (local or remote)'
- Enter Host and Profiling Port as previously specified on the server and click OK
- Now Session > Open Session
- Choose the one just created
Here are some screenshots of running JProfiler.

Method 2: Add agentpath to JAVA_OPTS
Stop the JVM (you can use ‘jk' shortcut command), add agentpath parameter to your JAVA_OPTS variable in ~/.bashrc and reread the file with ‘source ~/.bashrc'.
The library to be loaded is in our case {JProfiler install directory}/bin/linux-x64/libjprofilerti.so.
With jprofiler7 in your home directory and relative path, the example string to be added to JAVA_OPTS may look like

Or you can use an absolute path to libjprofilerti.so instead. Start JVM with Java Control Panel or js shortcut command. Check logs if you cannot connect.
Note: If you change any JVM/appserver settings in Java Control Panel the agentpath parameter will be removed so you may want to readd it. Alternatively you can ask support to add it to your static parameter set so that it survives JVM/appserver changes.

The JProfiler Manual contains much interesting information on the profiling process, we recommend to read it in full to get most of JProfiler.
