SQL Server Diagnostic Queries – Part 14

Introduction

I have recently started making videos for my YouTube channel. There are several different playlists, but the one for SQL Server is probably most relevant. Currently, I am working on a series of videos that dive pretty deeply into each of the queries in my SQL Server 2019 Diagnostic Information Queries. This post coincides with the SQL Server Diagnostic Queries – Part 14 video.

This particular video is the fourteenth in a series of videos that will go through each of the queries in my SQL Server 2019 Diagnostic Information Queries, explaining what each query does and how to interpret the results of each query.

In this video, we are going to cover just one query, but it is a very useful one!  This will be Query 33 – VLF Counts.

This query simply tells you the VLF Count for each database in the current instance of SQL Server. VLF stands for Virtual Log File.

My Diagnostic queries are available for free here.

Note: There are separate versions of these queries for every major version of SQL Server starting with SQL Server 2005. The general concepts in these videos are applicable to all versions of SQL Server, Azure SQL Database, and SQL Managed Instance.

Even if you are on an older version of SQL Server, these videos will be interesting and useful for you.

Final Words

If you have any questions about this post, please ask me here in the comments, in the YouTube comments for the video, or on Twitter. I am pretty active on Twitter as GlennAlanBerry. Thanks for reading!
