Mass Backup All Sessions

Migrating Extended Event Sessions from one server to another should be a simple task. So simple, one would think there was no need to give it a second thought, right?

Well, I have previously written about this topic, you are welcome to read it here. The article discusses quite a bit about scripting out your XE Sessions. One thing lacking in that article is the ability to script out every session on a server.

If you are still not using Extended Events, I recommend checking out this library of articles that will cover just about all of the basics concerning Extended Events.

New and Improved

What about scripting out all of the sessions in SSMS? Surely there is an easy way to do that, right? Well, you might think that. Let me step through the problem that I have seen in SSMS (and unfortunately it is not consistent).

First, from Object Explorer Details (or F5), let’s try to script a single session.

When scripting a single session from the “Object Explorer Details”, I have several sub-menus that allow me to script the session to a “New Query Editor Window”. Now, let’s see what happens when trying to script multiple sessions.

With several sessions selected, I try yet again to script the sessions and I get an unwanted result. Notice that the “Script Session as” option is grayed out and unusable. However, if I try it again (several times or maybe just once, your mileage may vary and it seems to not be relevant to version of SSMS), I may see something like this.

Tada! Luck was with me and it finally worked that time. So, what should I do to be able to consistently script all of sessions? Well, that comes with an enhancement to the script I presented in the prior article here.

Lets just dive straight into the new script.

This is a rather lengthy script, so I won’t explain the entire thing. That said, this script will produce the exact XE Session as it was written when you deployed it to the server. In addition, the script will ensure the destination directory for the event_file target is created as a part of the script.

I can definitely hear the gears of thought churning as you ponder about this whole scenario. Surely, you have all of your XE Sessions stored in source control so there is no need whatsoever for this little script. Then again, that would be in an ideal environment. Sadly, source control is seldom considered for XE Sessions. Thus, it is always good to have a backup plan.

Why

Sadly, I had the very need of migrating a ton of sessions from one server to another recently and the methods in SSMS just wouldn’t work. There was no source control in the environment. Building out this little script saved me tons of time in migrating all of the sessions for this server and also provided me with a good script to place in source control.

Conclusion

In the article today, I have provided an excellent tool for backing up all of your XE sessions on the server. This script will help create the necessary scripts for all of your XE Sessions (or even just a single session if you like) in order to migrate the sessions to a new server or place them in source control.
