JPicus is a JavaTM I/O analysis tool created by Pavel Genevski and other SAP employees in 2009. Its main purpose is to analyze I/O operations inside a Java application, providing JVM internal information, such as which thread opened a file. JPicus consists of the following major parts:

  • Agent - it plugs into the JavaTM Virtual Machine and collects I/O analysis data, like open file handles, I/O byte counters etc.
  • User interface - Eclipse based user interface that lets the user take a snapshot and analyze it

    • JPicus is similar to Java CPU and memory allocation profilers with the difference that it operates in the I/O domain.

    Since Feb 2014 JPicus has been available on github.com as an open source project. Only the agent and the API has been made open source, while the UI has been discontinued with the intention to create a HTML5 based UI.
