Ubuntu 14.04 64-bit I just installed frest gnuradio 3.7.8rc1 with control port enabled. I fetched gnuradio using git clone --recursive [GitHub - gnuradio/gnuradio: GNU Radio – the Free and Open Software Radio Ecosystem](https://github.com/gnuradio/gnuradio.git) Gnuradio enabled component shows - gr-ctrlport - - thrift However, I do not see any \*gr-ctrlport directory \*inside the gnuradio directory. Where is the source code for control port? Also there are no examples for using control port. ---

Dear Bob, A few months ago, I’ve asked a similar question ( [Re: [Discuss-gnuradio] Measuring performance of module](http://lists.gnu.org/archive/html/discuss-gnuradio/2015-06/msg00197.html)) and Tom gave me his paper in SIGCOMM. Inspecting GNU Radio Applications with ControlPort and Performance Counters Thomas R., Tim O’Shea, and Nathan Goergen You can get one in [Second Workshop of Software Radio Implementation Forum (SRIF 2013) - ACM SIGCOMM 2013](http://conferences.sigcomm.org/sigcomm/2013/srif.php) It does not fully describe how it can be used, though, through this you can get a hint.

There is a directory gnuradio-runtime/python/gnuradio/ctrlport where you in controlport related stuff. - - Volker Am 04.08.2015 um 10:09 schrieb Jeon: ---

The manual page linked above is from our weekly development builds. This points you to two apps that are installed with ControlPort: gr-perf-monitorx and gr-ctrlport-monitor. Other good places to look for usage is in our QA code. Look in gr-blocks for qa\_cpp\_py\_binding.py, qa\_cpp\_py\_binding\_set.py, and qa\_ctrlport\_probes.py. Tom
