3 * tcl_insflow.d - snoop Tcl execution showing procedure flow and delta times.
4 * Written for the Tcl DTrace provider.
6 * $Id: tcl_insflow.d 63 2007-10-04 04:34:38Z brendan $
8 * This traces activity from all Tcl processes on the system with DTrace
9 * provider support (tcl8.4.16).
11 * USAGE: tcl_insflow.d # hit Ctrl-C to end
13 * This watches Tcl method entries and returns, and indents child
19 * TIME(us) Time since boot, us
20 * DELTA(us) Elapsed time from previous line to this line
21 * TYPE Type of call (proc/cmd/inst)
22 * CALL Tcl command or procedure name
29 * WARNING: Watch the first column carefully, it prints the CPU-id. If it
30 * changes, then it is very likely that the output has been shuffled.
