ftrace

Arguments: function-spec &key condition break-before break-after inside not-inside print-before print-after

Starts tracing function-spec, which can be a function name (such as a symbol naming a function) or a function object (such as returned by function applied to a symbol naming a function). The related macro trace and top-level command :trace do not accept function objects as arguments.

Thus,

(ftrace #'foo)

starts tracing of the function object associated with foo. See also funtrace. See The tracer and Tracing function objects in debugging.htm.

The various keyword arguments are a subset those accepted by the :trace top-level command and have the same effect. See that page for details.

The :trace top-level command also accepts the keyword arguments break-all and print-all, which are not accepted by ftrace. To achieve the effect of specifying either of those, specify both the associated before and after arguments as true. Thus, to get the effect of :print-all t passed to :trace, specify :print-before t :print-after t to ftrace; similarly specify :break-before t :break-after t in place of :break-all t.
