![]() I’m also available for consulting if you just don’t have time for that and need to solve performance problems quickly. I’m offering a 75% discount to my blog readers if you click from here. If this is the kind of SQL Server stuff you love learning about, you’ll love my training. If you want to take this to the next level, it could also grab CPU from the ring buffer, file stats, and a whole lot more. For my part, I wrote sp_HumanEvents to help you spin up an Extended Event session to capture that.Īwful lot of prep work to catch blocking in a database with a pessimistic isolation level on by default, eh? Left Out Michael J Swart has a bunch of neat posts on that. Of course, from there you have to… do more to get the data. When it detects a deadlock, this interval falls from 5 seconds to as low as 100 milliseconds based on frequency of deadlock occurrences. Database Performance Monitoring Monitoring and Troubleshooting Deadlocks with SQL Monitor This article explains what SQL Server deadlocks are, why they occur, why they require immediate investigation, and the diagnostic data required to troubleshoot them. If you wanna get that, you have to be ready for it, and turn on the Blocked Process Report: sp_configure Most folks out there have no idea where to look for that stuff, and a lot of scripts that purport to get you detail are either wildly outdated, or are a small detail away from turning no results and leaving them frustrated as hell.īlocking, by default, is not logged anywhere at all in SQL Server. If Microsoft is embarrassed by how slow it is to grab all that session data, and they should be, perhaps that’s a reasonable first step to having Query Store live up to its potential. Rather than leave folks with a bazillion scripts and stored procedures to track them down, Query Store should add a view to pull data from there. Deadlocknessĭeadlocks are perhaps the more obvious choice, since they’re already logged to the system health extended event session. There are so many views and metrics out there, it would be nice to have a one stop shop to see important things.Īmong those important things are blocking and deadlocks. As much as I’d love other improvements, I think it’s also important to have a centralized experience for SQL Server users to track down tricky issues. I often find myself insisting on also having Query Store enabled. So much is missing from the details, configurability, and user experience. SELECT L.requestsessionid AS SPID, DBNAME (L.resourcedatabaseid) AS DatabaseName, O.Name. ![]() The only other way I could suggest is digging through the information by using EXEC SPLOCK (Soon to be deprecated), EXEC SPWHO2 or the sys.dmtranlocks table. The more I used third party monitoring tools, the more annoyed I get. You can use a deadlock graph and gather the information you require from the log file.
