asterisk users - Sep 2019 - How does verbosity work?

I'm trying to track down a CPU spike we are seeing in a system.

We have tracked down the spike to a single CPU and TID using that CPU. 
Indications are that it's asterisk running this TID.

I'm trying to figure out what asterisk is doing on this thread around that
time, but haven't been able to match the tid to anything I'm seeing in
asterisk debugging.
Is there a good way to diagnose what asterisk is doing for each thread id?

We enabled the debugging in the logger.conf.  Is there a verbose level that
would be recommended to track the threading?
Also, does the verbose help if it may be confbridge related?

If you are able to get a backtrace during the time the issue is occurring,
that could provide some insight. You can get a backtrace while Asterisk is
running by following the steps on [1].

Is there a verbose level that would be recommended to track the
threading?

Verbose is a very chatty debug that spits out information about what's
going on. You could try with verbose 3, and if that doesn't provide the
information you're looking for, you can dynamically bump it up at runtime.
If you are looking for something specific, you can always do a search in
the confbridge files for the verbose message and set the verbose level to
whatever number that message specifies.
