The Flight Recorder Graphical User Interface

The JFR graphical user interface allows users who are running a Flight Recorder-compliant version of Oracle JDK (that is Version 7 Update 4 or greater) to view the JVM's recordings, current recording settings, and runtime parameters.

The GUI is comprised of a series of tabs that aggregate performance data into the following groupings:

The data on these tabs is presented by way of an assortment of dials, chart, and tables. At the top of each tab is a sliding window, called the Range Navigator, with which you can expand or narrow the range of reporting; for example, if you see a group of events clustered around a specific time period, you can adjust the Range Navigator to include just those events, with the resulting data for just those events appearing on the tab components.
