[Discuss-gnuradio] Inspecting GNURadio Application with ControlPort and Performance Counter

[Simone Ciccia S210664]

Goodmorning,
I read an interesting paper on ControlPort to inspect the performance of 
GNURadio blocks.
I tried it and it's a very powerful toolkit, thanks for the release.
Actually I want to remote monitor a target machine in which the simple 
flowgraph of figure (target-flowgraph.png) runs.
In a host pc, where control port/gr-monitorix is installed I try the 
following command to monitor the target:

gr-perf-monitorix target-ip

but I receive the error reported in figure (host-control.png).

Do I forget something in the target machine or is there a particular 
procedure?

thanks you so much
