In the last segment, I wrote about the data types for the payload of an event in Extended Events. In that article, I also mentioned there is another component that is like a custom data type. That component is a map.
Maps are like a way of overloading the data… Read more
Today I get to talk about data types within Extended Events. This also means, I hope to be able to bring a little more clarity to the topic.
Among the several core concepts of Extended Events is the concept of storing event payloads / data. When an event fires, it would not be far-fetched to want to be able to review that data at some time after the fact. How often are you sitting there watching the system… Read more

The next component to discuss is Actions. I have discussed various aspects of events, schemas, categories and packages as some of the core concepts of Extended Events. Actions, is another of the core concepts.
In grammar, an action invokes memories of verbs and “to do” something. If you recall from… Read more
Working with databases, XML, and many software applications, it is not uncommon to deal with fixed schemas. In the database world, it is fairly fundamental to have some sort of schema. The schema represents the typing of the bit-strings that are being stored or presented. One might even call it… Read more
So far in these brief discussions about Extended Events, I have covered several core concepts including a basic introduction into what an Event is within Extended Events. For a recap on those articles, you can read this.

If you recall, an event is some point of interest that may or may not occur within an application. Obviously, if the event is triggered, then that point of… Read more
I recently delved into a brief explanation of Packages as they correlate to Extended Events. In that article, I left a couple of things un-said about packages – leaving them for this article.
Packages have a couple of descriptors (or classifiers) that can be useful to help figure out what… Read more

Beyond the metadata in the the catalog views and DMVs, there are a… Read more

Today will be the first of a few introductory level posts about Extended Events.
When dealing with Extended Events, there are a few ways to take a look some of the metadata. Not all metadata is created equal when dealing with Extended Events. Some of the metadata is pertinent to…

Well, today I present to you another opportunity for you to renew your love/hate… Read more
One of the biggest pains with Extended Events is the thing we love to hate – XML. XML is so foreign to many DBAs. It’s not relational and often brings nightmares of parsing and performance issues.
Despite that, Extended Events takes advantage of XML much like we have seen in… Read more
