Transact SQL :: Convert Or Change All Existing Traces To Extended Events In Server 2012
May 27, 2015
We are planning to convert or change all existing Traces to Extended Events in SQL server 2012. What is the procedure to convert custom traces. We have already created some below custom traces: like this we are planning to convert for all servers.
exec sp_trace_setevent @TraceID, 20, 23, @on
exec sp_trace_setevent @TraceID, 20, 8, @on
exec sp_trace_setevent @TraceID, 20, 12, @on
exec sp_trace_setevent @TraceID, 20, 64, @on
exec sp_trace_setevent @TraceID, 20, 1, @on
exec sp_trace_setevent @TraceID, 20, 21, @on

I am using this code for LongRunning Queries.
CREATE EVENT SESSION LongRunningQuery
ON SERVER
ADD EVENT sqlserver.sql_statement_completed
(
ACTION (sqlserver.sql_text, sqlserver.tsql_stack)
WHERE sqlserver.sql_statement_completed.duration > 60000
[Code] ...
Here Instead of writing to XML file how can send an EMAIL if a query runs more than 1 minute in my server ?

I use this code in a utility procedure (for performance testing) but it is really slow.
For example, a session with three events is taking 5 seconds to complete this query:
DECLARE @xml xml=
(
SELECT CAST(xet.target_data AS xml)
FROM sys.dm_xe_session_targets AS xet
JOIN sys.dm_xe_sessions AS xe
ON (xe.address = xet.event_session_address)
WHERE xe.name = @name
);
with data as
(
select
convert(varchar(128),convert(varbinary(128),'0x'+n.value('(action[@name="context_info"]/value/text())[1]','varchar(128)'),1)) context
, n.value('(data[@name="duration"]/value/text())[1]','int')/1000.0 duration
, n.value('(data[@name="cpu_time"]/value/text())[1]','bigint')/1000.0 cpu_time
, n.value('(data[@name="physical_reads"]/value/text())[1]','bigint') physical_reads
[code].....
So, I was wondering (considering the buffer is usually only holding a few hundred events)
1. Is this the wrong way to query data from a ring buffer?
2. Is there any way to make this code quicker?
3. Is it better to target a file store rather than a ring buffer for this?
select geometry::STGeomFromWKB(0x0106000000020000000103000000010000000B0000001000000000000840000000000000003D

I am trying to use xquery to get event data back from extended events. I am trying to use some sample data from Grant Fritchey but I am getting null records back. Below is the xml - I just want to retrieve a distinct list of the client_hostname and client_app_name.
<event name="login" package="sqlserver" timestamp="2014-02-19T23:53:54.299Z">
<data name="is_cached"><value>true</value></data><data name="is_dac">
<value>false</value></data><data name="database_id"><value>7</value>
</data><data name="packet_size"><value>8000</value></data><data name="options">
[Code] ....
The query I have that doesn't work is :
WITH xEvents AS
(SELECT object_name AS xEventName,
CAST (event_data AS xml) AS xEventData
FROM sys.fn_xe_file_target_read_file
('C:LoginTraceShared_0*.xel', NULL, NULL, NULL))
SELECT distinct top 1000 xEventName,
xEventData.value('(/event/data[@action_name=''Client_APP_Name'']/value)[1]','varchar') Client_APP_Name,
xEventData.value('(/event/data[@action_name=''Client_Host_Name'']/value)[1]','varchar') Client_Host_Name
FROM xEvents

I've setup a deadlock monitor using extended events like this.
CREATE EVENT SESSION [deadlock] ON SERVER
ADD EVENT sqlserver.lock_deadlock(
ACTION(package0.process_id,sqlserver.client_app_name,sqlserver.client_hostname,
sqlserver.database_id,sqlserver.database_name,sqlserver.plan_handle)
[Code] ....
Deadlock happened couple of days ago. I'm trying to determine the cause of deadlocks. What script should I use to pull that information to see what objects/processes caused deadlock?

I want to gather (and filter by) client ip address in an extended events session. So far, I have the sqlserver.login event added, but I can find no way to get client ip address added to the action or predicate.
I can filter by the pred_source field "session_nt_domain" or "nt_domain" but this is not always populated by all logins and also, this domain only lists machine name, such as FRED, as opposed to the full domain FRED.foo.bar.
Is it possible to gather login client ip address in an extended events session? Surely internal SQL Server processes have access to it because the login audit can populate client ip address.

I have an existing EE setup that captures all failing queries (see code below). The problem is that I also want to somehow capture RPC_starting so that I can see which parameters are passed in whenever a query fails. Is there a way to somehow capture those two events (error_reported & rpc_starting), but only capture rpc_starting when there is actually an error reported?Or maybe just an event on rpc_starting and somehow filter to only capture when there is an error?
Existing error_reported EE code:
CREATE EVENT SESSION [what_queries_are_failing] ON SERVER ADD EVENT sqlserver.error_reported (
ACTION(sqlserver.sql_text, sqlserver.tsql_stack, sqlserver.database_id, sqlserver.session_id,
package0.collect_system_time, sqlserver.transaction_id, sqlserver.username, sqlserver.client_hostname)
[code]....

I do have the following Extended Event session on my Dev box;
CREATE EVENT SESSION [sp_showplan] ON SERVER
ADD EVENT sqlserver.query_post_execution_showplan(SET collect_database_name=(1)
ACTION(sqlserver.plan_handle)
WHERE ([package0].[equal_uint64]([object_type],(8272)) AND [sqlserver].[equal_i_sql_unicode_string]([object_name],N'MyStoreProcedure')))
ADD TARGET package0.event_file(SET filename=N'E:DBA_AuditSP_Exec.xel',metadatafile=N'E:DBA_AuditSP_Exec.xem')
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
The idea is being able to capture the execution plan when the program invokes the store procedure, regardless of the database.
This works on my Dev box. When I manually trigger "MyStoreProcedure" from database A , the event is saved. The same thing happens when I do that from database B. Ok ... so far, so good.
So I went to the live production environment and setup my Extended Events session. But it's saving nothing. I was able to check that the store procedure was executed on several databases but my extended events session never grabbed the plan.
What could be the reason for this? Memory starvation maybe? Is there something I am doing wrong?

When you view the Extended Events "Watch Live Data" is the duration in milliseconds or microseconds? I'm assuming it's milliseconds, but if you look at the timestamp difference from start to complete it doesn't add up to the duration amount? It looks like it's just the difference between the timestamps?

In the past, I've combined server side traces with Perfmon successfully, which is pretty useful, I know that. I would like to do the same with Extended Events, so I can correlate and analyze the server side as well.

I wanted to demonstrate something about CXPACKET wait type. For the purpose of this demo I've created a query in AdventureWorks database that uses a parallel query plan, an extended events session that captured the wait statistics for a single session and a query that shows the extended event's data. I ran it and it worked fine. Then I dropped and recreated the event session (to clear the data), in a new window I wrote a transaction that updated the table fallowed by waitfor statement so the first query will be blocked for few seconds and ran the whole thing again. The select statement was blocked as expected (ran for 9 seconds instead on 1 second as it ran without the blocking), but the wait stats that I got were almost identical to the those that I got without blocking the query.
--Query that uses parallel query plan
With MyCTE as (
select top 50 * from Sales.SalesOrderHeader)
select top 10000 * from Sales.SalesOrderHeader, MyCTE
order by newid()

I am wanting to get/filter on all queries and procs that take longer than 2 seconds to run (I'll balance real values later) but I'm not sure which Action out of the XE that I need.
I am using SQL Server 2014 and thought I had used sqlserver.sql_statement_completed.duration > 2000 in a previous version.

I know very little about Extended Events, but I know it is supposed to be more powerful than Profiler. The SQL Instance involved is 2008R2. I was asked whether we could capture when a stored proc was called with a certain parameter. So for example, if dbo.usp_mystoredproc is called and is passed a value of '12345a' for @customer, can that be captured? I would want to know the time it was called, the parameter and parameter value. Probably would be interested in the SPID or LoginName as well.

I need to find any stored procedures that have not been used over a certain time period.
I have set up an extended events session to gather sp_statement_starting and _completed.
The trace returns the object_id's of many stored procedures. I then query the sys.procedures and plug in the object_id to return the stored proc name.
Do I have to repeat this process for every different object_id or is there a way I can query the trace results, using the object_id as my search criteria as one query ?

I am setting up extended events more or less just fine, however I am a bit confused as to how to read and load them into a table for querying. In particular the offset part - is there a way to load just a given dates worth in?
I've got the files configured to be 20MB before rolling over, the XE is running all the time.
So if i load in the full file now, say that covers 2.5 days worth, when I load it again tomorrow to get the updated data I'm also reloading today, which is a waste?
I presume I am going about this wrong, but lack an example that really goes into detail of practicalities of loading this data.

Existing table structure is below:
Table name: Student
Columns in Student are below:
Student_Id
Subject_Id
Quarter
Col1
Col2
Combination of Student_Id, Subject_Id and Quarter columns is the primary key. One student can take one subject in a quarter. Now the new requirement is a student can take multiple subjects in a quarter. So need to add another table like below:
NEW table name: Student_Subject and
column are below:
Student_id
Subject_Id
Quarter1
All the above three columns combination is primary key.
After the new table Student_Subject created,
remove Subject_Id column
from Student table.
When the user clicks on a button after selecting multiple subjects and provide col1 and col2 data then one row gets inserted into Student table and multiple rows gets inserted into Student_Subject table.
Is there any other table design that satisfies one student can take multiple subjects in a quarter?

I can only do one match at a time -- Like can only do either the sql_statement_(start and end), or sp_statement_(start or end). Is there any way to capture both in the same session? Or since I am adding both the events in the ADD EVENT section, can I query it somehow to get unmatched SP or SQL?
Code:
USE master;
GO
-- Create the Event Session
IF EXISTS(SELECT *
FROM sys.server_event_sessions
WHERE name='TimedOutSQL')

We were recently acquired and need to move our existing SSRS 2012 mail server from our internal SMTP service. The internal service doesn't need to have a 'real' account to send email out. Everything seems to be setup and running under the internal service.I think I need to change the Email Settings information in "Reporting Services Configuration Manager". Namely the Sender address and SMTP Server fields. But without actually making these changes, I don't see where it is going to ask for the password. Really hate to make changes on a production server.
Do I need to change the "Log On As" account in the "SQL Server Configuration Manager" as well? If so, does this need to be the same account as used in the Sender Address (above)?. there is a lot of ink about making additions to the "rsreportserver.config" file. Our existing file does not have any of these entries.

I have created a session in extended events and want to frequently monitor the events that i have filtered .The problem i am facing is i am not able to clear the previous data as we do it in SQL trace. i am able to see all the data that is occupied till now.whenever i start the test i want the current data only to be displayed.The work around is either delete the session and create a new one every-time which i do not want to do .I am able to see the CLEAR DATA FROM TABLE button but it is in Disabled state all the time.

We know we can use the event lock_deadlock and xml_deadlock_report to capture the deadlock info, however I also want to capture the execution plans for all of the SPIDs in the deadlock graph, how to output the execution plans to the extended events trace results either ? such as if there is an action for execution plan or workaround for it ?If there is no built in action for execution plan , may I know if we can add the customized info to the extended events results file also ? Such as when the deadlock related event happens , then we can run a query to get some info ,then added the info along with other info such as sql_text, dbname etc to the events trace results file either ? The reason is if we also know the execution plans when the deadlock happens, it is useful to turning the query based on the execution plans to reduce deadlock happening .

Hello experts. I have been searching for anything about this but found very little. What are the events logged in SQL Server Error Logs aside from Successful/Failed Login, Backup/Restore/Recover database and, start/init sql server? Can we configure this to log other events, like CREATE or DBCC events for example? If so, how? Thanks a lot.

Hi all,
I need to use the SQLDataSource in Visual Web Developer (VWD) 2005 Express websites. The SQLDataSource must have the .mdf data in the project application. But I have a volume of the .mdb data for evaluation by using T-SQL of the SQL Server 2005 Express and VWD 2005 Express program. Is it possible to convert existing data from .mdb to .mdf? If it is possible, please tell me what software program to use and how to do it.
Thanks,

Need calculating the count of events on each day. I have an event log table as shown below.
DECLARE @EventLog TABLE ( event_id int, status_id varchar(20) , dttm datetime )
INSERT INTO @EventLog
SELECT '100','Inplace','01/05/2015 05:00' UNION ALL
SELECT '100','Removed','03/05/2015 10:00' UNION ALL
SELECT '100','Inplace','05/05/2015 10:41' UNION ALL
[Code] ....
I need an output to look like on each day how many events were in place.
E.g.: for the month on May , Event_id 100 was inplace on 1st and removed on 3rd , so on 1st may 2 event_ids (100, 103) hence 2 .
event_ids - 103 / 104 and inplace the whole month and not removed. so its calculated the count as 2 til towards teh end of the month.
So I need to count of all each event_id in place for each day in may.

Currently I have a column with multiple postcodes in one value which are split with the “/” character along with the corresponding location data. What I need to do is split these postcode values into separate rows while keeping their corresponding location data.
For example:
PostCodeLatitudeLongitude
66000/6610042.6965952.899370
20251/2027042.1964719.404951
Would become
PostCodeLatitudeLongitude
6600042.6965952.899370
6610042.6965952.899370
2025142.1964719.404951
2027042.1964719.404951
how this can be done?
