Most of the time I subscribe to the KISS principle when it comes to authoring and SCOM. I rarely recommend customers developing related class hierarchies in their own MP’s. While making visualizations and routing of alerts far more functional, these complex relationships between classes can create much more complex MP’s…
There are times when an application installs a Windows Service that uses inconsistent naming. There might be a scenario where the Computer Name is inserted into the service name, or where random characters get generated in the service name. I wrote about this previously here: https://kevinholman.com/2011/01/20/how-to-monitor-a-service-with-unique-names-across-multiple-computers-using-a-wildcard/ Now, I have…

Check out my latest session from Silect’s Management Pack University, on Advanced MP Authoring using Fragments. Previous sessions:
There have been many posts about this over the years, and this is nothing new nor groundbreaking. However, I still run into customers who don’t fully understand how this works, how to configure it, and some of the good resources documenting this in the past have disappeared. So, this article…
Just publishing a little script I find handy when I need to free up space on my Hyper-V server. I have a home lab I use from time to time as well as my VMs hosted in Azure. These are hosted on Hyper-V. The VM disks in my lab grow…
One common issue I see regularly, is when customers upgrade their OS in place on Agent monitored systems, or replace and older OS with a new VM and a new OS, but keep the same server name. This practice causes issues for SCOM. You might see duplicate discovered instances across…
