|
|
* tcl_procflow.d - snoop Tcl execution showing procedure flow using DTrace.
|
|
* Written for the Tcl DTrace provider.

|
* $Id: tcl_procflow.d 63 2007-10-04 04:34:38Z brendan $
|
|
*
|
|
* This traces activity from all Tcl processes on the system with DTrace
|
|
* provider support (tcl8.4.16).
|
|
*
|
|
* USAGE: tcl_procflow.d # hit Ctrl-C to end
|
|
*
|
|
* This watches Tcl method entries and returns, and indents child
|
|
* method calls.
|
|
*
|
|
* FIELDS:
|
|
* C CPU-id
|
|
* TIME(us) Time since boot, us
|
|
* PID Process ID
|
|
* PROCEDURE Tcl procedure name
|
|
*
|
|
* LEGEND:
|
|
* -> proc entry
|
|
* <- proc return
|
|
*
|
|
* 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.
