WARNING! 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).
