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
In the previous article, I wrote about getting into some of the metadata to take a peek at session metadata relevant to deployed Extended Event sessions. Today, I will continue talking about metadata. One difference being that today I will focus on diving into the metadata of running sessions. 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…
The other day I wrote about that torrid love/hate relationship DBAs tend to have with working with XML. In that same post, I promised I would have a follow up post about XML in Extended Events.
Well, today I present to you another opportunity for you to renew your love/hate… Read more
