This file format is under development, and is subject to -change without notice. - -This file contains the following types of records: - -THREAD START -THREAD END mark the lifetime of Java threads - -TRACE represents a Java stack trace. Each trace consists - of a series of stack frames. Other records refer to - TRACEs to identify (1) where object allocations have - taken place, (2) the frames in which GC roots were - found, and (3) frequently executed methods. - -HEAP DUMP is a complete snapshot of all live objects in the Java - heap. Following distinctions are made: - - ROOT root set as determined by GC - CLS classes - OBJ instances - ARR arrays - -SITES is a sorted list of allocation sites. This identifies - the most heavily allocated object types, and the TRACE - at which those allocations occurred. - -CPU SAMPLES is a statistical profile of program execution. The VM - periodically samples all running threads, and assigns - a quantum to active TRACEs in those threads. Entries - in this record are TRACEs ranked by the percentage of - total quanta they consumed; top-ranked TRACEs are - typically hot spots in the program. - -CPU TIME is a profile of program execution obtained by measuring - the time spent in individual methods (excluding the time - spent in callees), as well as by counting the number of - times each method is called. Entries in this record are - TRACEs ranked by the percentage of total CPU time. The - "count" field indicates the number of times each TRACE - is invoked. - -MONITOR TIME is a profile of monitor contention obtained by measuring - the time spent by a thread waiting to enter a monitor. - Entries in this record are TRACEs ranked by the percentage - of total monitor contention time and a brief description - of the monitor. The "count" field indicates the number of - times the monitor was contended at that TRACE. - -MONITOR DUMP is a complete snapshot of all the monitors and threads in - the System. - -HEAP DUMP, SITES, CPU SAMPLES|TIME and MONITOR DUMP|TIME records are generated -at program exit. They can also be obtained during program execution by typing -Ctrl-\ (on Solaris) or by typing Ctrl-Break (on Win32).
