In LispWorks, tracing method is possible [1], don't know how to do that with SBCL. Trace is implementation specific, so you have to check SBCL manual to trace methods.
See this gist for LW here: https://gist.github.com/dmsurti/8364dcd636829eaf83d1
You could also tailor trace with options as listed here. [2]
