Installation

• Install the plugin (generic TeamCity plugin installation instructions)
  1. remove any previous copy of the plugin if it was installed (remove serverProfile.jar and yjp-controller-api-redist.jar from WEB-INF/lib directory, ensure you do not have .BuildServer/plugins/serverProfiler directory)
  2. copy serverProfile.zip file into .BuildServer/plugins directory
• copy files from the bin/<your platfom> directory on the plugin download page to the <TeamCity Installation Dir>/bin directory. Here <your platfom> is the name of your platform, like win32 for Windows XP, win-amd64 for Windows XP x64 Edition, etc.
• add -agentpath:<full path to YourKit agent>:

  JVM parameter to the TeamCity server (See related YourKit docs). Please take a look at the TeamCity documentation on how to add new JVM parameter
  Note that -agentpath:... should be specified as is, without -D prefix.
  You can check that the parameter is set correctly by making sure the lines starting with "[YourKit Java Profiler ...]" appear in your server console/output.

Usage

To start the profiling navigate to the Administration > Server Configuration page, TeamCity Server Profiler section

• On capturing the snapshot, the path to the saved snapshot is displayed. The profiling activity is logged into the server's console.
• Send the profiling results to the TeamCity Developers with a description of the problem.

CPU Profiling

• Click "Start" to start profiling
• Perform the action to reproduce the CPU load
• Click "Capture" to capture profiling snapshot, or "Cancel" to cancel profiling.

Memory Profiling

• When you believe that the memory consumption by the TeamCity server process is high, click "Capture" to capture the snapshot.
  Please note the this operation blocks server until the snapshot is fully captured. The UI for all the server users will not be refreshed until the snapshot is taken.
