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'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 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)
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?
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 );
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 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.
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
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.
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')
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 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.
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.
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 .
My problem is - I have a trigger for auditing the changes(insert/update/delete) in the database table.That is done and is working fine. But I need to have the client's IP address from where the changes are done. That I need in T-SQL, that means, not in any web form but in the SQL/T-SQL.
As I have checked many forums, I got that there is extended stored procedure in master database named xp_cmdshell which has xplog70.dll and when we execute this stored procedure with 'ipconfig' we can get the IP Address. But I do not need that in master database. I need that in my database say myDB.
So how to proceed further. I don't know whether to create extended SP which contains DLL or is there any other option.
I have problem to find Current IP address for client computer that have a connection to Specific DataBase Server .I can only know the IP Address of DataBase Server but not current client user IP address that I am seeking to find it ,How can I do this by using T-SQL command? Please write full T-SQL code .
I can retrieve "host" name of the current connection from "sysprocesses" system table(select host from sysprocesses). But is it possible to get the IP address of the client connection instead of host?
I could not find any stored procedures or extended procedures that would let me retrieve such information.
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.
I am logging into a SQL instance to run the following query:
DECLARE @ReturnCode int EXECUTE @ReturnCode = [master].dbo.xp_create_subdir N'sharemasterFULL' IF @ReturnCode <> 0 RAISERROR('Error creating directory.', 16, 1)
The share in which the folder is to be created has my account added with full permissions to create files. However this command fails unless I add the SQL Service account user with rights to the folder also.
Is this expected behaviour, is this something specific to extended stored procedures?
I am learning Extended event to capture deadlock which already happened, for this in my SQL SERVER 2012.. I am simulating a deadlock . With [URL]... where given a query to find the deadlock details using extended event here is the code..Retrieve from Extended Events in 2012.
SELECT XEvent.query('(event/data/value/deadlock)[1]') AS DeadlockGraph FROM ( SELECT XEvent.query('.') AS XEvent FROM ( SELECT CAST(target_data AS XML) AS TargetData FROM sys.dm_xe_session_targets st JOIN sys.dm_xe_sessions s
[code]...
This code creates a deadlock but when i run the above Extended events query to get the details of deadlock, it doesnot display any results.
I have a very interesting problem in T-SQL coding for which I can't figure out the solution. Actually there is a Line_1_Address column in our data warehouse address table which is being populated from various sources. Some sources have already concatenated house number + street address fields in the Line_1_Address column whereas one source has separated columns for both data fields.
Now I'm trying to extract data from this data warehouse table and I need to split the house number from street address and load it into separate columns in my destination table. In case there is no data for house number then I should load it as NULL.
The issue is that data in this Line_1_Address column is very inconsistent so I don't know which functions to use. Here is some sample data for your consideration:
Line_1_Address 101 E Commerce ST 120 E Commerce ST 2 Po Box 301 W. Bel Air Ave West Main Street, PO Box 1388
We have a multi-site AG and are demoting one of the remote sites out of the AG. In doing so, we've discovered that no logic exists to remove an IP address from the listener.
It seems that the ALTER AVAILABILITY GROUP MODIFY LISTENER logic lacks functionality other than ADD. [URL] ....
I'm afraid to just remove the IP address from the cluster object as that IP is also stored in the HADR systables.
select * from sys.availability_group_listener_ip_addresses select * from sys.availability_group_listeners
i have created the folowing function but keep geting an error.
Only functions and extended stored procedures can be executed from within a function.
Why am i getting this error!

I used the selfssl.exe tool to generate a certificate on my db server, successfully added to Personal Certificates in MMC, added R/W permissions for the service account to the cert, selected the new certificate in the protocols for mssql and restarted the service. So far so good, however when trying to connect from SSMS with encryption check box checked I get the following error:
A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server, Error: -2146893019)
The certificate chain was issued by an authority that is not trusted.
When I look in MMC, the only intended purpose for the certificate is "Server authentication" and I'm not able to add "Client authentication". Does selfssl.exe not support client authentication?
I'm trying to call the SQL 2012 SSIS packages deployed in SSISDB from batch files from another client system. But I couldn't find the DTExec.exe file in the 110Binn folder. How can I install this utility? Can I get this utility with client installation or do I need to install Server components which need license. I donot have license to install server component. how to install the DTExec utility without any licensing and provide me the Setup link where I can download and install.
