If you're looking for deadlock notification, rather than just blocked processes, here are some links worth checking out on how to monitor using Event Notifications:

http://weblogs.sqlteam.com/mladenp/archive/2008/07/18/Immediate-deadlock-notifications-without-changing-existing-code.aspx

http://www.sqlservercentral.com/articles/deadlock/65614/

The first link sets you log the event to a table, and then you can query the table to get any new events and get notified of them.

Additionally, I wrote an open-source tool a while back that did process block notification (not deadlocks, but telling you when one SPID is waiting on a lock held by another):

https://mssqlblockmonitor.codeplex.com/

As you can see, it's a bit rough around the edges and hasn't been updated in almost a year, but it does what I need it to do - you can add as many servers as you want, and it does immediate SPID block notification in the form of a tray bubble.

I'm not clear on how my posted answer didn't meet your requirements - you want to be notified immediately on a deadlock, and I provided some detail on setting that up using event notifications. Also, I provided a link to an open source tool a wrote that does this same type of notification in your tray, if that's what you're interested in.

If you want me to write the code for you, then I suppose my answer did fall a bit short, but is there any additional detail I can provide that would help you accomplish this? You originally posted the question three months ago, so I'd imagine that you've come up with your own solution by now if it was really critical.

Hi,

Does this help?
http://sqlmag.com/blog/enabling-email-alerts-sql-server-deadlocks

Note the salient points here:
You might need to turn on a trace flag
Create an alert or two for the specific error numbers you see
That alert then needs a notification to send an email
Test First!

And please confirm that you are using SQL 2008 as just because you posted in that topic it doesn't necessarily mean that your target version is sql 2008 ...

HTH

Hi,

I suggest a points split of http://#39204917 (375) and http://#a39568519 (125). I think Ryan contributed more than I did.
