To me it looks like your statistics are out of date.  Your estimates are WAY off from the actuals which usually indicates bad statistics.

I would start there.

Another thing - I...

I agree with both Phil and Michael.  Phil's comment about query store sounds like it is similar to Oracle's AWR.  Or so is my my understanding of query store.

And Michael...

My opinion - I wouldn't reinvent the wheel.  There are a LOT of good monitoring tools out there and I would just use one of those.

The good SQL monitoring tools...

Script debugging is always interesting.  The "best" (ie only) way I know how to do it is to find good breakpoints and run your code up until that breakpoint.  Next,...

I think I can answer both questions, but I would still recommend doing it in a test environment first.

So question 1 - my understanding is that SSRS hasn't had any...

Jeff - your approach is what our devs (myself included) are migrating to (I think).  Basically, the connection string gets stored in a settings file that is read on app...

As a guess - I would say that WinSCP probably has a list of valid fingerprints stored somewhere and when you connect, it checks the fingerprint against the known good...

That makes sense as the fingerprint is the fingerprint of the remote server.

I would recommend looking at some of the example scripts on the WinSCP site.  This one specifically should...

I would check to make sure the input is valid.  Double check the values you are passing into the properties of WinSCP.  For example, check the value of "$config.Configuration.HostName".  is...

On top of what ratbak indicated - when you say "Azure SQL", do you mean it is an Azure SQL Instance, an Azure SQL Managed Instance , or an Azure...

I expect you would get more help in a C# forum than a SQL Server forum, but I would reach out to your development team and work with them to...

Brandie - are you using SQL Aliases OR DNS Aliases?  If it is DNS aliases, you will likely need to include the instance name (for a named instance) when you...

I am pretty sure that SQL Configuration Manager aliases just put aliases on the server or on one individual workstation, not on all the client machines (don't quote me on...

One thing about the CPU - a lot of SQL Server operations are single-threaded, so having a lot of cores may not benefit you.  There are exceptions (as queries can...

hahaha... no, that isn't what I meant Grant... I am going to edit that to be 99% agree with that.
