I wanted to use the performance counters feature of GNU Radio, which requires getting ControlPort working. However, there seems to be a gap in the documentation.
I have read the information at http://gnuradio.org/ redmine/projects/gnuradio/wiki/ControlPort and http://gnuradio.org/doc/ doxygen/page_ctrlport.html, and a third document I don't remember that explained Performance Counters configuration. I have created ~/.gnuradio/config.conf as follows: [ControlPort] on = True edges_list = True config = /Users/kpreid/.gnuradio/k-thrift.conf [PerfCounters] on = True export = True and k-thrift.conf contains the suggested values [thrift] port = 9090 nthreads = 2 buffersize = 1434 init_attempts = 100 Then I run my program and run either gr-ctrlport-monitor or gr-perf-monitorx, which says: Could not connect to ControlPort endpoint at None:9090. I have the feeling there's an undocumented step missing here. What is it? I know that the configuration files are both being read because if I misspell the path to the thrift-specific file I get an error message that it doesn't exist.
