1N/A * rb_syscolors.d - trace Ruby method flow plus syscalls, in color.
1N/A * Written for the Ruby DTrace provider.
1N/A *
1N/A * $Id: rb_syscolors.d 27 2007-09-13 09:26:01Z brendan $
1N/A *
1N/A * USAGE: rb_syscolors.d { -p PID | -c cmd } # hit Ctrl-C to end
1N/A *
1N/A * This watches Ruby method entries and returns, and indents child
1N/A * function calls.
1N/A *
1N/A * FIELDS:
1N/A * C CPU-id
1N/A * PID Process ID
1N/A * DELTA(us) Elapsed time from previous line to this line
1N/A * FILE Filename of the Ruby program
1N/A * LINE Line number of filename
1N/A * TYPE Type of call (method/line/syscall)
1N/A * NAME Ruby method or syscall name
1N/A *
1N/A * Filename and method names are printed if available.
1N/A *
1N/A * WARNING: Watch the first column carefully, it prints the CPU-id. If it
1N/A * changes, then it is very likely that the output has been shuffled.
