Java Profiler Tool

The Java Profiler tool enables the collection and display of execution profile data on Java software source code bases of arbitrary size. It is a member of SD's family of Profiler tools.

Java Profiler Features

  • Java1 and Java2 compatible, covering Java 1.1 to 1.6
  • Provides execution counts on basic blocks, or timing profiles on methods
  • Works with standalone applications or servlets
  • Works with applications runninng on arbitrary JVMs (including embedded systems) or RealTime Java
  • Works with arbitrary subsets of source code base
  • Can accumulate data from multiple test runs
  • Handles tens of thousands of files
  • Extremely low probe overhead
  • Complete control over which Java class files are profiled (profiling tools using JVM facilities often must collect information for every class regardless of your interests)
  • Produces profile report by application, package and file
  • The probe installer component runs on Windows
  • Profile data display can run on any platform with a full JVM

The Java Profiler tool has an intuitively simple display. It shows

  • Available Profile Data (PFD) result files
  • Selected/accumulated/computed PFD files
  • List of files for which profile data is being collected
  • Locations of probe points in files
  • Browsable source text of file of current interest
  • Execution counts and relative execution frequency of each probe point on file source text
  • Color- and size- coded (hot is red and wide, cold is blue) overlay of frequency data on source code
  • Summary statistics for subsystems

The extremely low space and time overhead of test probes used by the Java Profiler tool makes it ideal for working with embedded or realtime programs.
