![]() ![]() Before shutting down a memory snapshot will be created. If you run into situations where Confluence is unresponsive and you are not able to trigger a memory snapshot, please ensure that you start Confluence with the onexit=memory parameter in the JVM options (as in the example below) and simply shut down Confluence. You are getting OutOfMemoryError's in your logs.Confluence's memory usage is higher than you expect.This can help us debug tricky performance problems which would otherwise be impossible to analyze remotely. 1 Answer Sorted by: 0 You need to enable profiler telemetry for JMeter prior to connecting to it, it can be done via -agentpath Java command line argument So if you launch JMeter as: java -agentpath:c:pathtoyourkityjpagent.dll -jar ApacheJMeter.jar you should be able to establish the connection. Screenshot: You can take a memory or CPU snapshotĪnalyzing a profiler dump enables Atlassian Support (or you, if you are interested) to see exactly what is happening in your application: what classes are using the memory, what is using CPU and so on. NET Profiler, Continuous Performance Monitoring YourKit Java and. For the CPU snapshot, this will take at least 30 seconds.

This file controls the startup parameters for Tomcat, so you'll need to restart it after making the changes.Īdd the 'agentlib' parameter to the end like this: ![]() To configure Confluence's JVM to use the YourKit agent, you need to add a parameter to CATALINA_OPTS in the bin/setenv.bat file in your Confluence application directory. IntelliJ Profiler What are Java Profilers Java Profiling is the process of performing a thorough analysis of a software application to identify memory or performance-related issues. For example, you might add "C:\Program Files\YourKit Java Profiler 6.0.12\bin\win32" to your PATH, via Control Panel, System, Advanced, Environment Variables. On Windows, add to your PATH environment variable the bin/win32/ directory underneath the YourKit installation directory. The YourKit documentation covers this in more detail. They should be easily applicable to other application servers and JVMs, however. The following instructions apply to Confluence and Tomcat installations with the Oracle (previously Sun) JDK. Note: YourKit version 7 is not compatible with the Confluence yourkit plugin. Download YourKit 6.0 for your platform and follow the installation instructions to install it. ![]()
