+# A regex to determine which requests should be traced.  This
+# is a regex to match the caller for rest client requests to
+# be able to selectively trace calls out of specific classes
+# and methods. It largely exists for test development, and is
+# not expected to be used in a real deploy of tempest. This
+# will be matched against the discovered ClassName:method in
+# the test environment.  Expected values for this field are:
+# * ClassName:test_method_name - traces one test_method  *
+# ClassName:setUp(Class) - traces specific setup functions  *
+# ClassName:tearDown(Class) - traces specific teardown
+# functions  * ClassName:_run_cleanups - traces the cleanup
+# functions  If nothing is specified, this feature is not
+# enabled. To trace everything specify .* as the regex.
