If you choose "Path" then "Ends With" and enter ".mdf" you can filter on all mdf data files. When you run procmon the first thing you are asked to do is to set up a filter (aside from the one time EULA!). What we will do is start procmon and create a filter for just the SQL Data files, because there are processes which constantly read and write to files we want to ignore the general "chatter". First you will need a copy of procmon (Process Monitor), which you can download from. CapturingĬapturing the data is very straight forward.

In this article I will be show how to measure the quantity and size of I/O requests in each database as well as being able to work out where your I/O's are hitting and then matching those up with physical tables.
