The following are examples of the results of running the rb_calls.d script.
|
|
|
|
This script traces activity from all Ruby programs on the system that are
|
|
running with Ruby provider support. In this example we see it running while
|
|
the Code/Ruby/func_abc.rb script is run.
|
|
|
|
# rb_calls.d
|
|
Tracing... Hit Ctrl-C to end.

|
|
func_abc.rb method Object::print 3
|
|
func_abc.rb method Object::sleep 3
|
|
|
|
We can see that the file func_abc.rb called each of the user-defined functions
|
|
included in the script; func_a, func_b, and func_c. It also called the print
|
|
object and sleep amongst other things. Interspersed in the output are calls
|
|
to new objects that are not tied to the program func_abc.rb. They are called
|
|
from the Ruby engine for some other reason.
