If you need to collect data from multiple different instances using the same configuration file, then you can just use the same extracted. Extract the contents of the zipped file in a folder. The tip that I want to talk about with this tool is that. The output from the scripts in the CustomDiagnostics section is captured in text files. Examine the extracted files. Change the i nstance name value to the appropriate SQL Server instance name.

Notice that capturing detailed traces can introduce significant overheads on the server. All output data files are captured inside this folder.


Changing the machine name from which the data needs to be collected: Additionally, SQLDiag can be configured to collect custom data such as the output of a. Here are some additional reference links if you are interested in learning more about the PAL tool.

You can make a copy of the SQLDiag. It provides similar reports as the SQLNexus tool. After you click on Finish, a command prompt window will open automatically and close once the PAL the analysis is completed.

How to use SQLDiag, SQLNexus and PAL tools to analyze performance issues in SQL Server

Additionally, the tool lets you add pre-configured custom diagnostics for Analysis Services configuration data, Mirroring configuration, Event log collection etc. Performance degradation during specific hours say between 2: A remote SQL server instance will work okay as well, but I would recommend using a local instance if possible.


Customers must have enabled this feature on their SQL Server aqldiag to be able to use it. Post was not sent – check your email addresses! Click Next on the Welcome screen.

If you need to collect data from multiple different instances using the same configuration file, then you can just use the same extracted.

Introduction to SQLDIAG for SQL Server Performance Monitoring and Tuning

I have read the privacy statement and understand I may unsubscribe at any time. I would suggest creating a shortcut for the SQLNexus. Allow the tool to run for the duration of the performance problems, while SQLDiag sqdiag the diagnostic data.


The answer is — it depends! This gets you closer to collecting just what you want. Sorry, your blog cannot share posts by email. Assuming that a particular SQL query was responsible for these CPU spikes, you can drill down into the SQLNexus reports and find out which particular query execution relates to the CPU spikes on the server and if it is the number of executions of that query that is responsible for the CPU spikes.


Standard reports will show you the cumulative information since the last restart of SQL Server instance and not for the specific timeframe that your are interested in – such as between 2: More information about this custom diagnostic is available in the FAQs section on Codeplex.

sqdliag As you may have noticed, some initial efforts are required, such as configuring your own custom configuration file, to capture meaningful performance data with the SQLDiag utility. Change the enabled option to true to enable perfmon data collection or false to disable collection.

Once the analysis is complete, PAL reports will open up automatically in a browser window.
