I improved the file-level latency query this month and made some other small improvements to a few other queries. Rather than having a separate blog post for each version, I’ll just put the links for all five major versions in this single post. There are two separate links for each version. The first one on the top left is the actual query script, and the one below on the right is the matching blank results spreadsheet.
The basic idea is that you should run each query in the set, one at a time (after reading the directions). You need to click on the top left square of the results grid in SSMS to select all of the results, and then right-click and select “Copy with Headers” to copy all of the results, including the column headers to the Windows clipboard. Then you paste the results into the matching tab in the blank results spreadsheet. There are also some comments on how to interpret the results after each query.
About half of the queries are instance specific and about half are database specific, so you will want to make sure you are connected to a database that you are concerned about instead of the master system database.
Note: These queries are stored on Dropbox. I occasionally get reports that the links to the queries and blank results spreadsheets do not work, which is most likely because Dropbox is blocked wherever people are trying to connect.
I also occasionally get reports that some of the queries simply don’t work. This usually turns out to be an issue where people have some of their user databases in 80 compatibility mode, which breaks many DMV queries.
There is an initial query in each version that tries to confirm that you are using the correct version of the script for your version of SQL Server.
Please let me know what you think of these queries, and whether you have any suggestions for improvements. Thanks!
