I was trying to use gr-perf-monitorx while running Bastian's gr-ieee80211 project. I was encountering the following error :

{
    unknown = /home/harsha_sdr/.Repos/gnuradio/gnuradio-runtime/include/gnuradio/rpcserver_ice.h:119: IceUtil::IllegalArgumentException: Ctrlport Key called with unregistered key (ofdm_preamble0::output % full)

I read about the possible reason for the error and updated gnuradio-runtime.conf . It now stands as

[DEFAULT]
verbose = False

# The maximum number of messages a block will store up before pruning
# the queue by popping messages from the front.
max_messages = 100


[LOG]
# Levels can be (case insensitive):
#       DEBUG, INFO, WARN, TRACE, ERROR, ALERT, CRIT, FATAL, EMERG
log_level = debug
debug_level = emerg

# These file names can either be 'stdout' to output to standard output
# or 'stderr' to output to standard error. Any other string will
# create a file in which to output the logging information. An empty
# string or no value here will ignore this level of configuration
# completely.
log_file = stdout
debug_file = stderr

# Used for advanced configuration of the logger
#log_config = /usr/local/etc/gnuradio/gr_log_default.xml


[PerfCounters]
on = True
export = True
clock = thread
#clock = monotonic

[ControlPort]
on = True
edges_list = True
config = # /usr/local/etc/gnuradio/ctrlport.conf

I am stilling facing the error , even after making the changes as suggested on the Control Port usage page. Can someone explain what is going wrong ?

What version of GNU Radio are you running, and are you certain that Performance Counters have been built into your system? Prior to version 3.7.3, Performance Counters were disabled by default at compile time. You would have to add the -DENABLE_PERFORMANCE_COUNTERS=True to cmake to compile them in. Version 3.7.3 now enables these by default.

You can tell if your installation supports Performance Counters by looking at $prefix/gnuradio/config.h and seeing if there is a line:

#define GR_PERFORMANCE_COUNTERS
