Jprofiler License
- Open the JProfiler installer. On a Mac, drag the JProfiler icon to drop on the Applications folder. Exit the installer dialog. Delete (Move to Trash) the installer file to save disk space. Use Finder to initiate JProfiler. The first time it opens, JProfiler enters Setup. Click Next to Evaluate for 10 days.
- JProfiler is a powerful tool that you can use to profile Java based applications in a dynamic way and enables you to analyze them in hopes of optimizing performance. With it you are able to.
- After purchasing a floating license, you will receive a license server that you have to run in order to be able to use JProfiler on your network. All JProfiler installations must have network access to this license server. The license server is a pure Java application and requires a 1.5 JRE or higher.
JProfiler is a top choice for many developers. With an intuitive UI, JProfiler provides interfaces for viewing system performance, memory usage, potential memory leaks, and thread profiling. With this information, we can easily know what we need to optimize, eliminate, or change – in the underlying system. JProfiler is an award-winning all-in-one Java profiler. JProfiler's intuitive UI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues. Please choose the license type you wish to purchase.
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.
Jprofiler License Server
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.
JProfiler is a commercially licensed Javaprofiling tool developed by ej-technologies GmbH, targeted at Java EE and Java SE applications.
Features[edit]
- JProfiler works both as a stand-aloneapplication and as a plug-in for the Eclipsesoftware development environment.
- JProfiler supports local profiling (analysis of applications running on the same machine as the JProfiler software) and remote profiling (analysis of Java applications running on remote machines).
- Enables both memory profiling to assess memory usage and dynamic allocationleaks and CPU profiling to assess thread conflicts.
- Provides a visual representation for the virtual machine load in terms of active and total bytes, instances, threads, classes, and garbage collector activity.
