Querying deadlock graph from SQL Extended Events

By Marcelo Fonseca,

Hello all,

This is my first time writing a SQL Server post.

I was studying last week about Extended Events and wrote this script to help identify deadlocks using the default XEvent system_health.

I'd like to share it and I'd appreciate if anyone could add suggestions, improvements or fix something, because I haven't tested it on many scenarios.

Basically, all you need is to force a deadlock error and run the script on SQL Server 2008+ filtering by date (if you want) and collect the results. It may take a few seconds to show the new event.

If the object name and/or index name were not shown, you can use the hobt_id value to query the object using sys.partitions (also on column hobt id).

I hope it may help anyone.

Marcelo
