# By popular request, Dmitry Yemanov adds some helpful performance guidelines pertaining to the “internals†of the database monitoring system (a.k.a. “MON$â€Â). The purpose is to assist those using this facility on heavily loaded systems to employ it in ways that provide the information you want while minimising its impact on the end-user experience.
