.TH j_syscolors.d 1m "$Date:: 2007-10-03 #$" "USER COMMANDS" .SH NAME j_syscolors.d - trace Java method flow plus syscalls, in color. .SH SYNOPSIS .B j_syscolors.d { \-p PID | \-c cmd } .SH DESCRIPTION This traces Java methods if the hotspot provider exists (1.6.0) and the flag "+ExtendedDTraceProbes" is used. eg, java -XX:+ExtendedDTraceProbes classfile This watches Java method entries and returns, and indents child method calls. If the flow appears to jump, check the TID column - the JVM may have switched to another thread. .SH OS Solaris .SH STABILITY Evolving - uses the DTrace hotspot provider, which may change as additional features are introduced. Check Java/Readme to see what version these scripts are based on. .SH EXAMPLES .TP Default output, # .B j_syscolors.d .PP .SH FIELDS .TP C CPU-id .TP PID Process ID .TP TID Thread ID .TP DELTA(us) Elapsed time from previous line to this line .TP TYPE Type of call (func/syscall) .TP NAME Java method or syscall name .SH 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. .PP .SH DOCUMENTATION See the DTraceToolkit for further documentation under the Examples, Notes and Docs directories. The example files may be especially useful as they aim to demonstrate how to interpret the output. .SH EXIT j_syscolors.d will run until Ctrl-C is hit. .SH AUTHOR Brendan Gregg [CA, USA] .SH SEE ALSO dtrace(1M)
