Using Hashtables in your SCOM scripts

    When we work with getting data out of SCOM via PowerShell, or building automations, something that can really help speed things up are Hashtables.   I was recently working with a customer to build a discovery for a new class, and get properties from other existing classes.  I had to build an array…

Alerting on SNMP traps in SCOM – Without discovering the SNMP Device

  Well, sort of, anyway.    I have written on SNMP monitoring in SCOM a few times: https://blogs.technet.microsoft.com/kevinholman/2011/07/20/opsmgr-2012-discovering-a-network-device/ https://blogs.technet.microsoft.com/kevinholman/2015/02/03/snmp-trap-monitoring-with-scom-2012-r2/ https://blogs.technet.microsoft.com/kevinholman/2015/12/16/how-to-discover-a-windows-computer-as-a-network-device-in-scom-2012/ https://blogs.technet.microsoft.com/kevinholman/2016/04/20/writing-a-custom-class-for-your-network-devices/   This one will be a little different.

Using SCOM AD integration – but with a CMDB instead of LDAP wizards

    AD integration has been around since SCOM 2007 first shipped.  The concept is simple – the ability to deploy agents as part of a build process to the OS, but with the SCOM agent left un-configured.  Then the SCOM agent checks with Active Directory in its local domain, and received management group and…

How to create a SCOM group from a SQL CMDB Query

Creating a SCOM Service Monitor that allows overrides for Interval Frequency and Samples
