Ejabberd tracing using ejabberdctl live

Hello, does anyone have any insight about the "ejabberdctl live" erlang shell. I am trying to trace the execution of ejabberd by using native Erlang tracing methods such as dbg:tracer\0 or fprof:trace\1. It seems that if i start an erlang shell using "ejabberdctl live" command, none of those functions are supported (its like the library isnt loaded). When i do the same in a normal erlang shell, they work.

Does anyone know a solution to using dbg and fprof while running ejjaberdctl live?

Error mssages:
