System Health Session and beyond


I had blogged extensively about System Health Session available in SQL Server 2008 and above. I had also demonstrated how the System Health Session can be used in conjunction with SQL Server Management Studio reports in previous series that I ran on my blog.

System Health Session Dashboard Reports for SQL Server 2008 and SQL Server 2008 R2 – A set of reports available for SQL Server 2008/SQL Server 2008 R2 which provide visualizations for the events tracked by the System Health Session. The reports can be used using the custom reports option in SQL Server Management Studio.

System Health Session Dashboard – Shows the basic information of the information that can be fetched from the System Health Session.

System Health Session Dashboard — sp_server_diagnostics and more – A look into the different issues tracked by the sp_server_diagnostics script and how to build visualizations using that information.

System Health Session Dashboard – sp_server_diagnostics – The basics of what is covered by the sp_server_diagnostics procedure and how to build visualizations on top of the data captured.

System Health Session Dashboard – Error Summary Report
– Shows information on how to write queries to fetch information about various errors tracked by the System Health Session. Shows information tracked by the enhanced System Health Session in SQL Server 2012.

System Health Session Dashboard – Health Summary Report
– Gives you information about the SQL Server instance health like CPU usage, memory etc. A screenshot of the report is shown below:

I have added UTC time formatting so that the time is shown in the same time zone based on the server on which you are viewing the report.

I will keep updating this post once I keep updating with the new reports. As usual, feedback is always welcome.

The report definitions (.rdl) can be downloaded from here.

Awesomesauce: Deprecated Features usages


SQLServer:Deprecated Features is a performance object that is available since SQL Server 2005. The number of deprecated features have definitely increased since SQL Server 2005. In SQL Server 2012, there are a number of deprecated features whose use on your SQL Server 2012 instance can be determined through the use of this performance object.

Some of the common features that you might be interested in finding out the usage are DBCC REINDEX, DBCC SHOWCONTIG, DBCC INDEXDEFRAG. Once you have found the usage of these, you can find out which application uses this by looking up the SQL Server default trace.

Example:

declare @tracename nvarchar(4000)

select @tracename = path from sys.traces where id = 1
select TextData, StartTime, EndTime, spid, ServerName, HostName, error, SessionLoginName ,ApplicationName, TransactionID
from fn_trace_gettable(@tracename,default)
where EventClass = 116
and (TextData like '%showcontig%' or TextData like '%reindex%' or TextData like '%indexdefrag%') 

Download the T-SQL script to find out the deprecated features being used on your SQL Server 2012 instance using the script below.

Script name: Deprecated_Features.sql

The above is a good way to determine the use of deprecated features and which requires a change in your SQL Server environment.

Awesomesauce: Perf Dashboard on Native SSRS


I had been asked the question about using the Perf Dashboard reports from a Reporting Services instance multiple times. Though this was not the intention of launching the SQL Server Performance Dashboard Reports but there is a compelling need at times to have these accessible from a web URL. In today’s age, you will find a lot of DBAs monitor their SQL Server instances remotely. Sometimes, there is another layer of complexity added to this when they want to just look at the health of the SQL Server instance by accessing a URL exposed through a corporate server in their environment. In such cases, you wouldn’t want to jump through a few hoops of setting up your VPN connection and blah blah.

So with all that in mind, let’s talk about how you can get your SQL Server 2012 Performance Dashboard to your existing SQL Server Reporting Services instance.

  • First you need to create a new Reporting Services Project using SQL Server Data Tools (SSDT).
  • Use the solution explorer to add all the existing performance dashboard reports from the C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Performance Dashboard folder.
  • Modify the project properties to ensure that the data source gets written to the same folder as the reports.
  • Create a shared data source pointing to your SQL Server instance.
  • Open each report that was imported into the project and modify the data source properties to use the shared data source that you created in the above step.
  • Modify the project deployment properties as shown below.

Now you are ready to deploy your Performance Dashboard SSRS project to your reporting services instance.

What can you do next?

You can now set up Report Server subscriptions for the set of reports that you wish to receive via email. You can get a status report of your SQL Server instance without even having to lift a finger and that to right in your mailbox! Smile

Note that Performance Dashboard is a tool which is provided “AS-IS” by Microsoft. The steps mentioned above will help you deploy the existing Performance Dashboard reports to a SQL Server Reporting Services instance. However, the failure to deploy these reports as mentioned above is not liable for support by Microsoft SQL Server Support team.
