+# Notes
+#
+# The point of this test is to make sure code is properly instrumented,
+# where instruments have the proper key (binlog or relaylog),
+# it is not to dive into statistics for each instruments.
+# Different test execution sequence in different platforms do make the
+# results vary, making the test results very sensitive to changes.
+# To ensure robustness:
+# - log file rotation is limited to file .000001 and .000002
