1N/A * py_syscalls.d - count Python function calls and syscalls using DTrace.
1N/A * Written for the Python DTrace provider.

1N/A *
1N/A * USAGE: py_syscalls.d { -p PID | -c cmd } # hit Ctrl-C to end
1N/A *
1N/A * FIELDS:
1N/A * FILE Filename of the Python program
1N/A * TYPE Type of call (func/syscall)
1N/A * NAME Name of call
1N/A * COUNT Number of calls during sample
1N/A *
1N/A * Filename and function names are printed if available.
1N/A * The filename for syscalls may be printed as "python", if the program
1N/A * was invoked using the form "python filename" rather than running the
1N/A * program with an interpreter line.
