jprofiler is not the prettiest tool you can find. most of the tools are focused on memory analysis, while i needed execution time analysis. most of them were buggy, some eventually worked but did not produce enough information or produced too much information, which is just as bad. i found thisĪnd wasted about 3-4 hours running through it. none of them worked well.

Jprofiler detached install#

just to be clear: a simple tool would be a tool i can install and use without reading a manual. tptp is a good, solid, tool but it is not a simple one to install and use.

however, tptp is no longer an option for me since it does not support mac os x.

in the past, i have used theĮclipse test & performance tools platform at the end of the day, i managed to cut the execution time of some processes by 50% and more, by usingĪs an eclipse user and a strong oss supporter, i first started searching for the open source alternatives. after tackling some obvious pain-points, i had to turn to help of a profiler.

The JProfiler Manual contains much interesting information on the profiling process, we recommend to read it in full to get most of JProfiler.A couple of weeks ago i found myself in a position which is well known to any professional java developer: my software was simply too slow. Alternatively you can ask support to add it to your static parameter set so that it survives JVM/appserver changes. 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. Start JVM with Java Control Panel or js shortcut command. Or you can use an absolute path to libjprofilerti.so instead. With jprofiler7 in your home directory and relative path, the example string to be added to JAVA_OPTS may look like -agentpath:jprofiler7/bin/linux-圆4/libjprofilerti.so=port=11002 The library to be loaded is in our case /bin/linux-圆4/libjprofilerti.so. 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’. Here are some screenshots of running JProfiler.

Enter Host and Profiling Port as previously specified on the server and click OK.

Choose ‘Attach to profiled JVM (local or remote)’.

ĭownload the same tarball to your linux PC (or correct one for you OS), unpack and run jprofiler from bin directory. # jprofiler7/bin/jpenableĬonnecting to .Bootstrap start. If you are profiling frequently you may prefer method 2 though. Method 1: Start JProfiler with jpenableĮasier 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.

Some of you may prefer to download RPM or shell installer.

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.Īs 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.ĭownload JProfiler to your home directory and unpack it e.g. JPA/Hibernate probe supporting Hibernate 3.x/4.x, EclipseLink 2.3+ and OpenJPA 2.1+.

JProfiler’s GUI helps you detect performance bottlenecks, memory leaks and resolve threading issues. JProfiler is an award-winning all-in-one Java profiler and an alternative to jvisualvm. We show 2 methods of installing JProfiler agent and accessing JVM to be profiled from remote location.
