The Missing Event Schedule, and the, Auto Reset Timer, properties are not values that can be overridden on a unit monitor. A brief overview of the overridable properties can be found at How to Create an Override for a Monitor.
We always follow the pattern of "target a class, but override for a group". I think this generally means in this situation we would create the following assets:
- classA and classB
- Missing Event Unit Monitor for ClassA (30)
- Missing Event Unit Monitor for ClassB (60)
Something like that.
Its not as clean, or as reusable, as we might like, so I'm hoping someone will post a more 'reusable' / DRY'er way to achieve this.
I wonder if an alternative might be to have a custom script monitor reading the event log at some interval, which is configured outside of SCOM (e.g. registry, config service, etc)? Just thinking out loud..
