One of your SQL Server instance shows a major dip in performance or throughput, affecting all the user databases. You notice that the slow interludes coincide, as if orchestrated. On investigation, it appears that several transactions running over that period were using a lot of space in tempdb. However, which of them, if any, are causing the tempdb bottleneck, and why?

This article explains ten ways that SQL Monitor tackles the problem of scaling out the coverage of a single, lightweight monitoring system, and so allows your teams to maintain the health and performance of larger collections of databases and higher numbers of monitored SQL servers. Read more
Jeremiah Peschka, a tech lead for SQL Monitor development, explains the new SQL Server configuration options available for the data repository, and how enabling them might improve SQL Monitor performance, when reading and writing monitoring data. Read more
Phil Factor explains how SQL Monitor helps focus performance tuning efforts on the tables and queries where 'rogue indexes' might be a significant problem, and then how to identify both 'missing' indexes that might be beneficial to the overall workload, and those that are unused or duplicated, and so are doing more harm than good.

In this article, you'll learn how to detect and remove a common cause of SQL Server query performance problems: reliance on implicit datatype conversions. We'll use a combination of plan cache queries, extended events, and SQL Monitor. Read more
Phil Factor sets out with the modest aim of giving you enough of an introduction to waits to better understand the wait information you get from a SQL Server monitoring tool like SQL Monitor, and the rather overwhelming amount of information available in the underlying DMVs and Extended Events.

SQL Multi Script can easily be persuaded to run queries at the server level rather than the database level. It is also able to combine results from many databases even if the results aren't identical but have some different columns. Phil Factor demonstrates how this works, when collecting a set of performance counters from all databases on a distribution list of servers. Read more
SQL Multi Script does one thing and does it well: it will run whatever script or scripts you select, on a list of databases, and collate all the results neatly. However, it has a surprising number of uses. Phil Factor explains how it works and then uses it to search 100 databases, for occurrences of a string, in about 7 seconds. Read more
Jamie Wallis explains how SQL Monitor can both reveal quickly who ran a deployment, and when, and automate the incident-response workflow to ensure it's dealt with swiftly. By extending such workflows to development and test servers, as well as production, the feedback cycle starts earlier, and you can stop problems from ever reaching the users. Read more
Phil Factor on the fill factor, pages splits and index fragmentation, and how SQL Monitor can help you decide if a custom fill factor for certain indexes might help alleviate performance issues. Read more
