Prevent Alerting based on Time of Day
If we recognize that CPU spikes between 2:00 am and 3:00 am on a server, and it is due to our backups taking place, is there a way to prevent alerts during that timeframe? Or possibly another approach, can we preventalerts is we see a certain process is running and consuming the CPU?Thanks,Kate

put the box into maintenance mode during that time. you could easily setup a scheduled task to run a script to put machines into maint mode every night or when resource utilization will be high.Hope this helps!Scott Moss

If we put the box into maintenance mode for the one hour, I believe if a critical event occurs with the box, we would not be alerted. Is there a way to prevent just the CPU alerts during that time of day? Can rules/monitors be disabled based on time?

You can put a single object into maintenace mode, for example only a processor. When the object goes out of maintenace mode a check is made, to see the current state to make sure you dont miss and alerts.Anders Bengtsson | Microsoft MVP - Operations Manager | http://www.contoso.se

We see an alert from the "Total CPU Utilization Percentage" monitor almost daily in the early morning hours. Backups are running during this time, users are not on the system - so we are not concerned enough to alert. When looking at the target, it is the Windows 2008 operating system. If I were to put this object into maintenance mode, I would be preventing alerting on other monitors. Is there a way to just disable this monitor during the off hours for this one server?Maybe another way to approach the situation is to ask if others are using this particular monitor? If so, what tuning have you implemented? If not, what works for you for monitoring CPU resource constraints that are affecting server performance?Thanks,Kate

I wanted to bump up this thread. This remains a request of our user community. How can we avoid specific alerting (like high CPU Utilization) for a certain portion of the day?
I want to avoid putting the whole server into maintenance mode since we would like to continue to receive other alerts during that timeframe (i.e. if disk space is running out).
Thank you,
Kate

As Anders said above, you can place just the CPU object into Maintenance Mode.

I apologize if I am overlooking something obvious. When I look in a diagram view, I do not see a CPU object. Discovered Inventory - Windows Server 2008 Processor - returns nothing.
When I launch Health Explorer from one of my CPU alerts, I see under Performance, "Total CPU Utilization Percentage - Microsoftr Windows Serverr 2008 Standard (Windows Server 2008 Operating System)".
Isn't this monitor targetted at the Windows Server 2008 Operating System? If I were to put an object into Maintenance, would this 2008 OS object be the one? If I did that, wouldn't it suppress alerts from all other monitors for
this target?
Correct me if I've misunderstood any of the above.
If there is a way to place just the CPU object into Maintenance Mode, please let me know how I can do that.
Thanks,
Kate

Hi Kate,
You're correct. I think that the only way is disable original monitor and create
your own with custom schedule.

Anders,
Can you explain the process of how to put a single object into maintenance mode? I can not find any documentation for this anywhere. If you could provide some steps to do this as an example it would help me very much.
Thanks,

Hi,
Think that you can use the Get-MonitoringObject command and get-monitoringobject, take a look at

I don't think that helps me in what I am looking to do. The situation I was running across was lets say I got a disk space alert, but I would not be able to action the alert until tomorrow. I wanted to place that disk drive, and only that disk
drive into maintenance mode, so I would not get any more alerts for that disk, but I would still receive all other alerts for its server. The way I found to do this was to go to monitoring, active alerts, and right click on the alert in question
and select maintenance mode. I then clicked start maintenance mode, and chose the option selected objects only, and the time period I wanted the drive to be in maintenance mode. I have been using SCOM for a couple months now, and so far I have
not seen this documented anywhere, which is odd because this is can be very helpful.
Anyway, thank you for replying!
