I get the following error when trying to the run gr-perf-monitorx
against a
flow graph that has an RTL_SDR radio as the source. I recompiled both
rtl_sdr and gr_osmosdr after enabling performance counters in gnuradio.

The odd thing is that it works fine when I do not have an RTL_SDR radio
attached. In that instance gr-osmosdr simply attaches a null source
instead. This seems to point to the RTL_SDR source. Has anyone
used gr-perf-monitorx with a RTL_SDR source?

This gut buried in my inbox. Any updates on your success with this? Are

Not a problem - It was under a VM, so that is probably what was causing
I ran it at home on bare metal with a HackRF and didn't have any issues.
