Let us send notifications when 3-state monitor changes state
A LOT of companies (all my customers) have a workflow where they have Warning being the proactive alert and Critical being the "send to on-call" staff alert.
The problem is that SCOM only trigger a notification when the alert is created or when it is switching resolution state. This means that if an alert is sent to the low-prio channel when the 3-state monitor raises a Warning alert, no notification will ever be sent to the high-prio channel as the alert transitions to Critical.
This is, honestly, such a basic notification strategy that ANY OTHER monitoring product i've used handles this.
I recall being promised in the early SCOM 2007 TAP that it would be something Microsoft would look into, and that's more than a decade ago.
To get around this, we're building work-arounds using automation tools (SCORCH, SMA, Task Schedulers) och custom rules that "update" alerts that has a new severity.
A quick google also tells me that this is a fairly common request as well. I can only assume that most people do not realize that those monitors will not generate a notification when going red when they already have an alert.
Confirmed fixed as of SCOM 2012 R2 UR11, and SCOM 2016.
Haven' it been fixed on 2012 R2 UR11?
"Alert subscriptions are not always fired for 3 state monitors
This update allows for configuration of a 3 state monitor to raise alerts; whose severity is in sync with monitor’s health state. One can create a subscription to be notified on modification of alert severity. Even if the monitor’s state keeps toggling between warning and critical, severity of the alert keeps being updated, and a notification fired on an update to the severity of an alert."
