How do we find what features each SQL Server instance has?

The journey began in 2008 where I officially started working in the field of IT (IT). Starting the first semester of school I realized a special attraction towards databases and automation. I have been involved with databases such as Microsoft SQL Server / Oracle Database, data analysis and automations using the command line (CLI), Visual Basic for Applications and Python. Through years of experience I have developed these capabilities so that I can make my life easier. For me, the purpose of every IT guy and every office worker is to have the knowledge so that through tools he can work a little but produce a lot. Through this his website DataPlatform.gr I try to offer knowledge and propose solutions to everyday problems.

In this article we will see a query that I have made so that we can easily find the specs of each SQL Server instance. This query can run in any version without needing any conversion as it is dynamic.

What can we see through this query?

• The Server name with the door
• What version is
• Which patch is installed
• The server collation
• The CPU number
• The Physical RAM that the machine has and the Max-Min memory that we have configured for the instance
• The average CPU load of the last hour through the default extended event that SQL Server has installed System Health
• The total size of the databases (Data and Log files)
• When was the last instance start-up?
• If it is enabled DAC
• The price we have set for Max DOP, blocked process threshold and cost threshold for parallelism
• Performance counters such as Page Life Expectancy, the Buffer cache hit ratio and other.

But there is a problem

As the field to find the size of RAM on the machine changed in the newer versions its name from physical_memory_in_bytes in physical_memory_kb in the view sys.configurations the query must be written dynamically. That is, to run a different query depending on the version we have.

Along with this change came the addition of availability groups. So I just check if this object exists and one of the two queries runs accordingly. Alternatively, of course, we can look at it ResourceVersion if it is before version 11 (SQL Server 2012).

How can we run it en masse on all the instances we have

The easiest way is to have it set to SQL Server Management Studio all our connections to the instances and run the query on all of them together.

To do this we go to View, Registered Servers:

There we choose under the Database Engine, right click on Local Server Groups and we press on New Server Registration…:

This is how we start filling all the servers we have. We only need the ServerName with its port and the credentials we connect to:

After adding the ones we want, we simply right-click on the folder we added them to (Local Server Groups) and New Query:

By adding the query to this new window and executing it, it will run us in a result set all the information we want:

*Because the machine I ran the query on didn't have access to other instances, I just went through the registered servers three times the same for the example.
