hi,

I'm using SQL SERVER 2022. I've created a simple extended event just for experimental purposes, but it doesn't appear to capture any events. Could you pls review the script below and let me know if you see anything wrong? Thanks!

CREATE EVENT SESSION [testsession] ON SERVER 
ADD EVENT sqlserver.database_created
ADD TARGET package0.event_file(SET filename=N'C:\test\test.xel')
WITH (MAX_MEMORY=4096 KB,EVENT_RETENTION_MODE=ALLOW_SINGLE_EVENT_LOSS,MAX_DISPATCH_LATENCY=30 SECONDS,MAX_EVENT_SIZE=0 KB,MEMORY_PARTITION_MODE=NONE,TRACK_CAUSALITY=OFF,STARTUP_STATE=OFF)
GO

To clarify, I have sysadmin rights on the server (my home computer). I tried the following steps.

create a test database
right click package0.event_file, select view target data
no events appear in the session tab

Did you start the session?

ALTER EVENT SESSION [testsession] ON SERVER
STATE=START;

Yes

View the live data before creating the database.

You only view data after the live data view has been opened, so if you create the database before viewing live data you don't get any output in the view

However if you open the XEL file you will see the data prior to opening the live view.

Yeah, it's as @Ant-Green has it. You have to have the live data window open first. It only shows active events. However, you can directly open the file, and it will open in another window that is the Live Data window, but for the file. That gives you sorting, grouping, searching, and all the rest of the functionality of the live data window, but on the file.

With the exception of adding a step #0 to start the session, I repeated your posted steps on SQL2022 in the same order, Viewing Target Data after the CREATE DATABASE call completed; the event is displayed.

I'm blanking on what to try next (maybe try opening the .xel file directly from the file system?), but your steps as I performed them look correct.

What did you change to make it so?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Well, not sure. I think I just deleted all of the .xel files in the folder and retried. Seemed to work finely after that.
