Profilers in the MarketĬomparison for Mac (named license with two years of support): Product ![]() Problematic patterns in memory and CPU usage in Java and Scala code This tutorial aims to enable you to identify and resolve This option is actually preferable to alternative A and unless you have to profile an already running JVM, you should take this route. Use the integration wizardĮxecute the command line uutility bin/jpintegrate in the JProfiler distribution on the remote machine and select your application server and follow the subsequent steps. When you start session, the JProfiler GUI will connect to the remote machine and you will see profiling data. On the local machine, create a session of type "Attach to profiled JVM (local or remote)", specify the host name of the remote machine and the profiling port that was set with jpenable. If the profiled JVM is not listed, execute jpenable as the same user that runs the Tomcat JVM. The JVM will then be ready for profiling. Attach to the running Tomcat processĮxecute the command line utility bin/jpenable in the JProfiler distribution on the remote machine and select the Tomcat process. ![]() There are two ways to get remote profiling to work: A. On the local side you need a full installation of JProfiler. No further configuration is required on the remote side. In any case, you should extract the JProfiler tar.gz file for Linux on the remote machine.
