Use condor_config_val tool to display the value of configuration knobs.

By default it will look at the config of the machine where you are logged in, or you can give it the name of a remote machine in your pool with "-name".  If you use the "-v" (or -verbose) option, condor_config_val will tell you which config file set the knob and/or tell you the default built-in value.

Below are a couple examples in my pool.  There are other useful switches, like "-writeconfig" and "-dump".  See the condor_config_val man page.  

In most recent versions of HTCondor, this knob defaults to True.

[tannenba@submit-5 ~]$ condor_config_val update_collector_with_tcp
true

[tannenba@submit-5 ~]$ condor_config_val -v -name xxxxx.chtc.wisc.edu update_collector_with_tcp 
UPDATE_COLLECTOR_WITH_TCP = true
 # at: <Default>
 # raw: UPDATE_COLLECTOR_WITH_TCP = true
 # default: true
