SCOM 2012 Maintenance Mode Scheduler

We believe that core to any monitoring system is the ability to send out accurate alerts. SCOM sends out many valuable alerts but will flood e-mail boxes and paging systems during maintenance windows.  We set out to build a maintenance mode scheduler that anyone can quickly and easily use to prevent these floods of useless information.


  • Easily access the new web based maintenance mode scheduler from any browser.
  • End users will thank you at how easy it is to pick a computer, group, object, and even a subscription with a start time and end time. The app calculates the minutes for them and schedules a future maintenance window.
  • The manage tab will make it easy to see and manage any upcoming maintenance windows and identify any gaps.
  • The new integrated dashboards make it feel like the scheduling maintenance mode was always there.

Schedule a group of Computers, Databases, or any objects in the group into maintenance Mode.

One Click Maintenance Mode

Another great feature is the ability to do one click maintenance mode from any server.  This means is you can place the same shortcut on the desktop of your all your servers.  With one click, the IT administrator can put the server into maintenance mode.


After the shortcut is clicked, the web page automatically detects what server you are on and puts the server into Maintenance Mode with no interaction.


Dashboards Integrated Into The SCOM Console




Most organizations only use the alerts from SCOM.  Now you can schedule your complex subscriptions into maintenance mode.  You can choose to send the alerts that where queued up or discard them.


Manage any upcoming maintenance windows and identify any gaps

Automatic Alert Resolution in SCOM

One of the more confusing screens in SCOM is the Automatic Alert Resolution settings screen.

The text is very vague as to what is does.  Kevin Holman recently updated his blog post to clearly identify what they mean.

You can read the excellent full post here.

To sum it up:

Resolve all active Alerts in the new resolution state after: =   “Resolve ALL alerts no matter what source (rule or monitor), as long as they haven’t been last modified within “30” days. (where 30 days is the default value)”

Resolve all active alerts when the alert source is healthy after:“Resolve all MONITOR based alerts where the targeted object has returned to a healthy state, and hasn’t been last modified within “7” days. (where 7 days is the default value)”

The New Way with PowerShell and Chocolatey
