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
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
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
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
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
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
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 annual SQL Server Professional migration is about to begin. Many of us will be descending upon the city of Seattle for a week of training and networking at the PASS Summit. The week in Seattle will invariably begin and end on different days for many people. And since… 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.
As a follow-up to the introduction to what an Event is, it… Read more
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
Welcome to the second Tuesday of the month. And in the database world of SQL Server and the SQL Server community, that means it is time for TSQL2SDAY. This month the host is Jen McCown (blog / twitter), half of the MidnightDBA team, and the topic that… Read more
This post will serve as the landing page for a series I am calling 60 Days of Extended Events. The purpose of these posts will be to help somebody progress through the Extended Events Concepts and become more proficient at implementing and using them.
The 60 days of XE will… Read more
So far, I have talked about some of the metadata associated with Extended Events. But I have not yet started to dive into the individual components of that metadata.
Today I want to start diving into some of this data a little deeper as we progress through some of the… Read more
Today, I continue on with exploring some of the metadata concerning Extended Events. To date, I have explored various aspects of session metadata whether the session is running or stopped. Today, I want to take a step back and look at the framework that helps give us this tool.
The… Read more
So far, in this series, I have discussed the means to view the metadata associated with Extended Events. I also demonstrated some quick and simple means to retrieve some metadata via the catalog views and DMVs.
Beyond the metadata in the the catalog views and DMVs, there are a… Read more
