Reset Health on Alert Closure.

SCOM has two alert types. Monitors and Rules. 
Both need to be handled differently when resolving. Normally Monitor alerts will self close when the alert has been resolved, but in some cases we have users who will inadvertently close a monitor alert. 
 It can also be difficult to have users fully understand the difference between a rule and a monitor, and act appropriately. If the monitor alert is closed, and the underlying issue not resolved (eg low disk space), then you will not get further alerts unless the health state changes back to healthy and then unhealthy again.

Ideally it's easier to tell users just to "close" alerts, and not to have "reset health".

This posting on the Technet Wiki was one solution I'm implementing to make it easier for users.

Emailing outstanding alerts from SCOM

Sometimes it's good to have a list of SCOM alerts mailed out, especially if your SCOM environment is not connected to a job management system.  
In our environment, we email out a list of alerts that are in the "New" resolution state, as a gentle reminder for people to sort it out.

I've split the email up with monitors and rules separately, due to the way we use SCOM. But its very straightforward to alter the script to not have this.
Add it as a scheduled task.
It's available on the TechNet Wiki

IIS Log rollover for OMS with SCOM alerting

Microsoft recommends that machines loaded into Microsoft Operations Management Suite (OMS that are running IIS, have their log rollover set to hourly.

However, once machines are added into OMS, it's entirely possible the IIS logs are changed, new sites are rolled, etc.  And there is no easy way to see if that had been done, or stay on top of it.

 As a solution I throw an alert in SCOM if any site is not configured to 'hourly'.
 
See my TechNet wiki articlefor a howto, and a handy script to set up IIS Log rollover via PowerShell.

I published an article about displaying OMS updates in SCOM.   Looks like I picked up the gold award System Centre from the Technet Wiki Ninja's. yay!
