Sql-server – Change Name of Extended Event Session

extended-eventssql server

I've just recently started working with Extended Events and am loving it. However, I ran into a small annoyance and am wondering if there's a way around it.

I had a very simple ExEvent session that was named "DatabaseFooActivity". Once I got comfortable with that, I expanded it so it was looking at more than just Database "Foo", meaning that the session name is no longer accurate. Now, when I right-click the session, there's no rename option and when I go into it's properties, the Session Name field is grayed out.

In short, can you change the name of an Extended Event session after it's been created, without dropping and recreating it?

No, there is no way to rename an Extended Events session without dropping and recreating it. The NAME property is not part of the ALTER EVENT SESSION syntax, nor is it supported by sp_rename. Simply use SSMS to script and recreate the session easily. You don't lose anything by doing this.

Someone mentioned "I think only sqlserver.rpc_completed event will give you complete SQL command including parameter values." Please review answer below:

Found the answer.

The login event is correct and the network protocol is exposed via the options_text action. options_text was always blank for me previously and this needs to be set on via SET collect_options_text=(1). An example session might be: -

CREATE EVENT SESSION [Login] ON SERVER
ADD EVENT sqlserver.login(SET collect_options_text=(1)
    ACTION(
    sqlserver.session_id
    ,sqlserver.username
    ))
ADD TARGET package0.ring_buffer
WITH (
    MAX_MEMORY=4096 KB,
    EVENT_RETENTION_MODE=ALLOW_SINGLE_EVENT_LOSS,
    MAX_DISPATCH_LATENCY=1 SECONDS,
    MAX_EVENT_SIZE=0 KB,
    MEMORY_PARTITION_MODE=NONE,
    TRACK_CAUSALITY=ON,
    STARTUP_STATE=ON
)
GO

And this would then populate options_text with something like: -

network protocol: TCP/IP set quoted_identifier on set arithabort off set numeric_roundabort off set ansi_warnings on set ansi_padding on set ansi_nulls on set concat_null_yields_null on set cursor_close_on_commit off set implicit_transactions off set language us_english set dateformat mdy set datefirst 7 set transaction isolation level read committed

I found this out be chance by creating a session from the "Connection Tracking" Microsoft shipped extended events template.

That template includes "SET collect_options_text=(1)" and I wasn't previously aware such an option existed.

An example is also given in this sql-server-performance article. The last screenshot shows options_text populated with "network protocol: LPC.." LPC is shared memory.
