Azure OMS Workspace Settings Disappearing

Posted on September 15, 2017 by Cole McDonald

We've seen some interesting behaviors in Azure with the Healthservice Agent which provides the connection to SCOM in our hosted environment and OMS in Azure.  The management groups registered with the service (Healthservice - Microsoft Management Agent - MMA for short) seem to disappear every once in a while.  We suspect it happens during updates to the agent (extension if you're deploying from the Azure portal).

Recursive SCOM Subgroup Member function

Posted on August 18, 2017 by Cole McDonald

Sounds Fancy!  The problem I was having was that SCOM doesn't have a default way to look at all of the members of a group/subgroup tree in a convenient way.  The Get-SCOMGroup cmdlet doesn't have an option to recursively search any subgroups it finds.  It requires all kids of clunky Powershell to enumerate all of that if you need it.  I needed it.

5 Obstacles to Long-Term Success with Power BI

Posted on August 08, 2017 by George Bryant

My wife rolls her eyes every time I pull out Microsoft’s Power BI to analyze our personal bank statement data. Perhaps she doesn’t want me to know how much she spends each month on Starbucks Grande Chai Lattes… no whip. The reality is, I utilize Power BI whenever possible. In fact, these days I find it hard to engage in a business intelligence strategy discussionwithout Power BI being part of the conversation.

Setting SCOM Gateway Failover using Powershell

Posted on April 03, 2017 by Cole McDonald

Microsoft's System Center Operations Manager has much more power than the interface allows access to.  Of exceeding importance in an enterprise setting is building high availability into our systems.  SCOM includes much of this by default in the management structures.  The interface no longer reflects these settings, but they're still available to us through Powershell.  Here's a little script I use in our environment for bringing new gateways online.

Learn Powershell in 5 (More) Painless Steps: Data - Movement

Posted on March 16, 2017 by Cole McDonald

We've dealt with what types of data we can store in increasingly complex ways. It's time to start dealing with a discussion of "we've got it, what can I do with it? Let's start with the basics of object oriented programming.  An object is an instance of a class.   OOP, there it is!

If we think of our programs we're writing in terms of a series of blocks of code which accepts specific types of data in, does stuff to them, then hands them off to another block of code to do more stuff with, the method of moving that data becomes important. If it's all within a single computer, huge custom objects can be made and stuffed into a variable and that variable can be passed between each of the blocks of code to work on just the pieces of information it needs to do its specific job.

Learn Powershell in 5 (More) Painless Steps: Data - Storage

Posted on March 06, 2017 by Cole McDonald
In our previous series on learning Powershell, the very first topic of discussion was the storage of data.  In my opinion, the 2 most important things in computing are interface and data structure.  As developers, our interface to the data is using varible naming conventions that make sense.  Each of us have a personal style, but using descriptive names for our variables serves us when we inevitably have to revisit our own code a year from now.  Comments, variable names, and formatting make it easier to get back to work rather than spending time figuring out what we were thinking a year ago.

Learn Powershell in 5 (More) Painless Steps: Data - Types

Posted on February 27, 2017 by Cole McDonald
We've taken the time to learn how to use Powershell to grab a bunch of information.  We've discussed how to use it to do stuff and some of the types of things we can do with it.  It's time to dig a bit deeper into how we're dealing with the information we're gathering to make it easier, faster, stronger to use once we've gathered it.  This will get even more geeky than we've done so far.  Hold on to your keyboards, this could get messy.

On to the future with Powershell...

We're a month and a half out from when I started my 5 Painless Steps Powershell learning series.  It was a smashing success.  I was hoping a few dozen people would find it useful.  It was viewed by over 2500 people.  Yikes!

Learn Powershell in 5 Painless Steps - Decisions

Posted on February 13, 2017 by Cole McDonald
DevOps = Developers + Operations.  What if you're in Operations and don't have a developer at your disposal?  That should never stop you from making your job easier and more efficient.  Powershell is a scripting language from Microsoft that is already on your Windows PC and Servers and more recently, open sourced to the OSX and Linux communities.  It ships with a great minimalist development environment (Powershell ISE). 
 
The problem is that all of the tutorials out there either assume a background in scripting and programming, or act as nothing more than command references.  I'm hoping to enable you to automate your own workflows even if you've never programmed before.  You only need to learn 5 things: Storage, Input, Output, Decisions, Loops.  Everything you do manually is made up of these 5 things.  Every programming language is made up of these 5 things.
