/*
* j_syscolors.d - trace Java method flow plus syscalls, in color.
* Written for the Java hotspot DTrace provider.
*
* $Id: j_syscolors.d 58 2007-10-01 13:36:29Z brendan $
*
* This traces Java methods if the hotspot provider exists (1.6.0) and
* the flag "+ExtendedDTraceProbes" is used. eg,
* java -XX:+ExtendedDTraceProbes classfile
*
* USAGE: j_syscolors.d { -p PID | -c cmd } # hit Ctrl-C to end
*
* This watches Java method entries and returns, and indents child
* method calls.
*
* FIELDS:
* C CPU-id
* PID Process ID
* TID Thread ID
* DELTA(us) Elapsed time from previous line to this line
* NAME Java method or syscall name
*
* If the flow appears to jump, check the TID column - the JVM may have
* switched to another thread.
*
* WARNING: Watch the first column carefully, it prints the CPU-id. If it
* changes, then it is very likely that the output has been shuffled.
* Changes in TID will appear to shuffle output, as we change from one thread
* depth to the next. See Docs/Notes/ALLjavaflow.txt for additional notes.
