tcl_syscalls.d - count Tcl calls and syscalls using DTrace. tcl_syscalls.d { -p PID | -c cmd } This traces activity from all Tcl processes on the system with DTrace provider support (tcl8.4.16). Any Evolving - uses the DTrace Tcl provider, which may change as additional features are introduced. Check Tcl/Readme to see what version these scripts are based on.

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. tcl_syscalls.d will run until Ctrl-C is hit. Brendan Gregg [CA, USA] dtrace(1M)
