Why? The sky is falling and everybody thinks the database has blown up. You appear to have a corrupt database and nasty IO errors.

Checking the Health of your CLR

Having a tool to be able to monitor CLR health will be essential as you deploy more and more managed code within SQL Server. Extended Events offers a great lightweight means to do just that. This article shows how to deploy a session that will capture the various changes with CLR objects within our database environment. In addition, you will be able to capture various conditions related to performance or problems with the managed code. You may even recognize some of the CLR events from the system_health session.

Dynamics AX Event Session

There are many many uses for Extended Events. In this article I show a quick session setup that can be useful in the troubleshooting of various different problems (most probably performance related) with Dynamics AX.

Correlate SQL Trace and Actions

In the world of profiler and SQL Trace, these actions were an actual part of the payload for the Trace event. In XE, these actions are more like add-ons. I go into further depth about what an action in XE is – here. I recommend reading that article. Due to that, I won’t be diving into great detail here about what an Action is.
