/*
|
|
* pl_syscalls.d - count Perl subroutine calls and syscalls using DTrace.
|
|
* Written for the Perl DTrace provider.
|
|
*
|
|
* $Id: pl_syscalls.d,v 1.1.1.1 2015/09/30 22:01:09 christos Exp $
|
|
*
|
|
* USAGE: pl_syscalls.d { -p PID | -c cmd } # hit Ctrl-C to end
|
|
*
|
|
* FIELDS:
|
|
* FILE Filename of the Perl program
|
|
* TYPE Type of call (sub/syscall)
|
|
* NAME Name of call
|
|
* COUNT Number of calls during sample
|
|
*
|
|
* Filename and subroutine names are printed if available.
|
|
* The filename for syscalls may be printed as "perl", if the program
|
|
* was invoked using the form "perl filename" rather than running the
|
|
* program with an interpreter line.
