Backup Deployed Sessions

There is a wealth of information within Extended Events. Throughout this series, I have been working on exposing that wealth of information. A good bit of this information happens to be the metadata for Extended Events, and another bit of this information is tied to the metadata for deployed Sessions.… Read more

SET Operations and Metadata

Having covered the core concepts of deployed session metadata (events, actions, targets, predicates), there is one more topic to cover. This is more of a subset of those concepts in that this applies to more than one of the core concepts, but it isn’t really a stand-alone topic. This is… Read more

Session Target Metadata

With the ability to find the metadata for deployed session, events and actions firmly under the belt, the natural progression would lead one to find the metadata for the target(s) attached to a session.

Exploring the metadata for the core components of Extended Events Sessions can be an extremely fruitful… Read more

Session Action Metadata

In a previous article, I introduced the core concept of Actions. In that article, I explained that an Action is a means to attach additional data from the stream to the event payload.

Recently, I have been covering various aspects of how to build an event session as well… Read more

Session Event Metadata

There is a wonderful amount of metadata available to be perused in Extended Events. Part of the trick is to know where and how to find it. I started to dive into the investigation of this metadata with the exploration of the Deployed Extended Event Session Settings discussed here.… Read more

Deployed Session Settings

You may recall that I wrote about how to look at the deployed session metadata. Today, I will be talking about deployed sessions again. And it may even be considered metadata as well. This time around, the metadata I will be discussing is a little bit different but will build… Read more

The Extended Event GUI

In the previous article in this series I shared the basics around assembling an XEvent session. The method used in that article was via TSQL script. In this article, I will introduce the Extended Events GUI. While I prefer to use TSQL to create and manage my sessions, the… Read more

Assembling a Session

Up to this point, I have taken a lot of time to discuss the various components of Extended Events. There is good reason for that. The components I have discussed are essential pieces of Extended Events and are critical to building useful sessions.

Previously, I only touched lightly on the… Read more

Freecon – Oct 27 in Seattle

Just over a week ago I announced that SQL Solutions Group was getting ready to host a day of training, FREECON if you will, in Seattle as a prelude to the PASS Summit of 2015. You can read all about that here, with registration being here.

While I… Read more

Predicate Order is Critical

I have mentioned predicate order previously and wanted to make sure I drive home the importance of the predicate order when dealing with Extended Events. This is an important topic because it can be very helpful in maintaining a reasonably performing event monitoring system.

The proper order of a predicate… Read more

Comparison Predicates and Event Data

In the previous installment, I began covering the topic of predicates. In that article I demonstrated that there are multiple types of predicates. There are two objects that fall into the predicate category and then there are data comparison predicates (those that are not objects).

The two objects are pred_compare… Read more

Predicates and Event Data

At one time or another, a predicate has been the best friend or worst enemy of the data professional. If the predicate was forgotten during an update for a specific user account, then the predicate suddenly became the worst enemy. On the other hand, when the predicate was properly used… Read more

Map Data Types in Extended Events

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

Data Types in Extended Events

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.

To a small degree, I introduced the topic when I wrote about event payloads. And I also did a very quick… Read more

Storing Event Data

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

Actions In Extended Events

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

Extended Events and Fixed Schemas

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

Extended Events – Event Anatomy

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.

As a follow-up to the introduction to what an Event is, it… Read more

Extended Events – Events

After thrilling dives into the XEvent Core Concepts of packages, channels and objects, today we have the core concept of “Event.”

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
