Refreshing Power BI Usage Metrics Report Credentials

Stephanie Bruno fixes a credentials issue:

Have you ever had a Usage Metrics Report just stop refreshing? At the bottom you’ll see a little message that tells you to check the credentials. But you don’t have access to the Usage Metrics Report dataset in the list of datasets in the workspace because it’s hidden! So even if you wanted to delete it and nicely ask it to start again, you can’t do it from the workspace. What can you do? Well, you can delete the Usage Metrics Report dataset with the Power BI Rest API.

Read on to see how.

Setting Breakpoints in Powershell Scripts

Patrick Gruenauer does a bit of debugging:

The Set-PSBreakPoint cmdlet sets a breakpoint in a script. When you are troubleshooting a script it could be helpful to know what’s going on in a particualar step or workflow. In this blog bost I will give you an overview and the basics you can build on to troubleshoot and investigate your script. Let’s jump in.

One of these years, I’m finally going to learn command-line debugging. I grew up in the IDE era and so never took the time to learn that skill.

Creating a Self-Signed Certificate in Powershell

Tom Collins says ‘trust me’:

Use the Powershell cmdlet New-SelfSignedCertificate

Warning: I only ever use this method for testing purposes – never use for Production environments. A typical test would be for  SQL Server Network Encryption SSL Certificate Management

Encryption strategy  should be part of a wider review of Database Security Countermeasures against hacker attacks

For more details check the Microsoft documentation but here are some notes on some of the parameters  attached to the Powershell cmdlet – New-SelfSignedCertificate.

Read on to see how you can create the certificate and use it in SQL Server. Connections will complain (and rightfully so) about the self-signed certificate but you’ll be able to try functionality which requires a certificate in an environment in which you don’t have one available for whatever reason.

Creating Calculation Groups in Power BI Desktop via Powershell

Phil Seamark helps those who are stuck lacking tools:

recently shared on Twitter a 7-module learning path on MS Learn that teaches all you need to know about calculation groups in Power BI. This learning path is an excellent course, and I highly recommend it. However, as part of this exchange, I received a reply from someone lamenting that calculation groups are unusable in organisations that will not allow non-Microsoft applications. Power BI Desktop does not currently have UX enabling you to create/manage calculation groups in a Power BI Model, so the most common method today is to use 3rd party tools such as Tabular Editor.

This exchange is not the first time I have heard this feedback, so I decided to share a technique showing how you can use Microsoft tools. The approach used in this article uses PowerShell but can quickly get translated to VS Code or other scripting environments.

Searching for SQL Server Backup Locations

David Fowler can’t remember where those backups went:

Sometimes I find remembering where a particular server sends its backups to a nightmare.

You might have servers backing up to different locations, you might have different locations for individual databases and different locations for your fulls, diffs and logs. You might be trying to get your head around a customer’s set up, where the backups make no logical sense at all.

Whatever you’re up to, at some point, for some reason you’re going to need to access your backup location to get at the files.

Read on for a Powershell script which can help out with this task.

Reading the SQL Server Error Log

Lee Markum has two ways to read the SQL Server error log:

Reading the SQL Server Error Log is important when troubleshooting many issues for SQL Server. Some example issues would be errors related to Always On Availability Groups, long IO occurrence messages, and login failures.

Unfortunately, the SQL Server Error Log can be very full of information, making specific things hard to find, especially if you’re just visually scrolling the Error Log. Even if you’re recycling the Error Log each day and keeping 30 or more days of error log, on a busy system, the error log can still be quite full, even for a single day.

Finding Assigned Synapse RBAC Roles in Powershell

Charith Caldera wants to know your access level:

One of the key use cases that most customers face difficulties while retrieving or assigning the role-based access control in Azure Synapse Analytics, that they cannot find the correct usernames, group names or the service principal names using the PowerShell cmdlet “Get-AzSynapseRoleAssignment”. The PowerShell cmdlet only provides limited information and it’s difficult to understand since that contains the object IDs. 

Read on for a script which helps with this problem.

Changing Default Powershell Behavior via Commands or Proxies

Jeff Hicks gives us a choice:

I’ve often told people that I spend my day in a PowerShell prompt. I run almost my entire day with PowerShell. I’ve shared many of the tools I use daily on Github. Today, I want to share another way I have PowerShell work the way I need it, with minimal effort. This specific task centers on files and folders.

As you might expect, I am constantly creating, editing, and managing files. I do all of this from a PowerShell prompt. I rarely use the start menu to find a program to launch. My challenge has always been finding the files and folders I’ve recently been using. Get-ChildItem is naturally the PowerShell tool of choice, but I’ve finally gotten around to making it work the way I need.

Not having done either of these before, I’m not sure which would be my preference, as I’d like to make sure it’s easy for me to remember later how I got to this non-standard state in case I need to replicate it elsewhere or if somebody else is at my keyboard. That’s one nice thing about the .bashrc file: it’s just there and well-known enough that people can look for changes there.

Pre-Staging Log Shipping Backups with dbatools

Jess Pomfret doesn’t waste time:

Log shipping is a SQL Server feature used for disaster-recovery where the transaction log backups are ‘shipped’ from your production instance to a secondary instance. This enables you to cutover to this secondary server in the event of a disaster where you lose your primary instance. Log shipping is not a new feature but is still quite popular.

Recently I was tasked with setting up Log Shipping for a reasonably large production database. I didn’t want to initialize the secondary database with a new full backup as I was already taking full and log backups of the database. In this case we have the option of initialising the database by restoring the full & log backups up to the latest point in time and then configuring log shipping.

Read on to see how you can use dbatools to do this easily.
