Deploying CUs to Multiple Instances with Powershell

Jeff Iannucci embraces the power of the shell:

This all started because we had some 14 new SQL Server 2017 instances that we were setting up, but we hadn’t yet applied the most recent cumulative update that we are using in our environment.  I started using the Update-DbaInstance cmdlet in the script below to apply to one server, but then I looked at the list of outstanding requests and thought about something Buck Woody once told me.

“You don’t have time for that. You’re going to be dead soon.”

He’s a fantastic fellow, but we should all be grateful he didn’t become a physician.

Migrating Databricks Workspaces

Gerhard Brueckl has made DatabricksPS better:

I do not know what is/was the problem here but I did not have time to investigate but instead needed to come up with a proper solution in time. So I had a look what needs to be done for a manual export. Basically there are 5 types of content within a Databricks workspace:

– Workspace items (notebooks and folders)
– Clusters
– Jobs
– Secrets
– Security (users and groups)

For all of them an appropriate REST API is provided by Databricks to manage and also exports and imports. This was fantastic news for me as I knew I could use my existing PowerShell module DatabricksPS to do all the stuff without having to re-invent the wheel again.

I’ve used DatabricksPS and really like it for cases where I’d have to loop with the Databricks REST API—for example, when uploading files.

Building an Azure Usage Report with Powershell

June Castillote shows us how we can use Powershell to get usage data from Azure for our subscriptions:

In the section above, it would be common for the command to return many thousand objects especially for long date ranges. To prevent overwhelming the API, the Get-UsageAggregates command only returns a maximum of 1000 results. If you’ve saved the $usageData variable as covered in the previous section, you can confirm it by using running this command $usageData.UsageAggregations.count.

What if there are more than 1000 results? You’re going to have to do a little more work.

Knowing how much you’re spending is critical in an Op-X world like Azure or AWS.

SQL Assessment API Public Preview 2

Ebru Ersan announces public preview 2 of the SQL Assessment API:

SQL Assessment API is a new mechanism to evaluate configuration of your SQL Server for best practices. The API methods are used by means of a SQL Server Management Object (SMO) extension and new cmdlets in SqlServer PowerShell module. API is delivered with a ruleset that is highly customizable and extensible. It can be used to assess SQL Server versions 2012 and higher, both on Windows and Linux.

Read on for instructions on how to install and what has changed since public preview 1.

Using the Power BI API

Jeff Pries takes us through the Power BI API with Powershell:

The Power BI API is a way of essentially bypassing the web interface of and asking questions directly to the back-end of the service (without bypassing security). Using this allows you to issue a command, such as “Give me a list of all of the workspaces” and receive just the result data in a bulk data format. While outside the scope of this exercise, the API also allows reading actual business data from Power BI assets and even manipulating assets.

For my first attempt at interacting with the API, I decided to try the Microsoft developed Powershell Cmdlets. These are a set of free Powershell commands which can be installed on your workstation and then will query the Power BI API and return results in a standard way without the need to write any code (C# or otherwise) or understand how to read a JSON response.

Jeff does more than just hit API endpoints, though, so read the whole thing.

Listing Windows Users with Powershell

Jack Vamvas shows us how we can use Powershell to list Windows users in an Active Directory group:

Question: How can I use Powershell to list out Windows users? Are there Powershell cmdlets which can report on Windows users ?
Answer: There are “out of the box” Powershell cmdlets which will support the requirement . How you apply the powershell cmdlets will depend on how much detail is required.

Jack has a few examples here as well.

Using dbatools Instead of RDP

Garry Bargsley shows how we can use dbatools to do some of the things which we might naturally do with Remote Desktop:

So you hear this spread across the Twitterverse and Blogosphere. You should not RDP your SQL Servers to do administrative work. My nature has always been to troubleshoot issues from the server in an RDP session.

When I received a disk space alert on a development system I was about to RDP and do my thing. But I said wait, let me approach this from a different perspective…

To the rescue is dbatools as always seems to be the case these days.

Remoting is much less resource-intensive and it lets you scale out to dozens, hundreds, or thousands of servers without any more effort on your part. It’s rare that you get constant scaling, so take advantage of it where you can.

File Sizes in dbatools

Chrissy LeMaire gives us several ways to format file sizes with dbatools:

Within dbatools, you may notice file sizes are pretty and human-readable.

That was some C# based magic created by Microsoft PFE and creator of PSFrameworkFred Weinmann. In the background, SQL Server often gives us different types of numbers to represent file sizes. Sometimes it’s bytes, sometimes it’s megabytes. We wanted to standardize the sizing in dbatools, and thus the dbasize type was born.

Human-readable file sizes are great but they make it difficult to compare when piping sets of data to Format-Table. Knowing how to override this when necessary gets you the best of both worlds.

Goodbye, Powershell 5.1 Ad

Chrissy LeMaire has a Powershell ad blocker:

I really abhor the new ad in the PowerShell 5.1 console and it seems there’s no hope of Microsoft making it go away.

After a long, involved Twitter conversation with the community and the PowerShell team that confirmed it’s impossible for the advertisement (?!) to be easily removed, it looks like the only solution is to bypass it. Przemysław Kłys has a great suggestion to emulate the old prompt that totally works!
