How to Override a Rule or Monitor
Overrides change the configuration of System Center 2012 – Operations Manager monitoring settings for monitors, attributes, object discoveries, and rules. When you create an override, you can apply it to a single managed object or to a group of managed objects. You must have Advanced Operator user rights to create and edit overrides.
The use of overrides is key to controlling the amount of data that is collected by Operations Manager. When you create a monitor, rule, or attribute you target it at an object type, but often the available object types are broad in scope. You can then use groups and overrides together to narrow the focus of the monitor, rule, attribute, or object discovery. You can also override existing monitors, rules, attributes, or object discoveries that are from management packs.
Overrides that apply to a class are applied first, then overrides that apply to a group, and finally overrides that apply to a specific object. For more information, see Using Classes and Groups for Overrides in Operations Manager and Using the Enforced Attribute in Overrides.
The following procedure overrides a monitor, but you can also use these steps to override a rule, attribute, or object discovery. You must have Advanced Operator or Administrator user rights to create an override.
To override a monitor
Log on to the computer with an account that is a member of the Operations Manager Advanced Operator role.
In the Operations console, click Authoring.
In the Authoring workspace, expand Management Pack Objects and then click Monitors.
In the Monitors pane, expand an object type completely and then click a monitor.
On the Operations console toolbar, click Overrides and then point to Override the Monitor. You can choose to override this monitor for objects of a specific type or for all objects within a group. After you choose which group of object type to override, the Override Properties dialog box opens, enabling you to view the default settings contained in this monitor. You can then choose whether to override each individual setting contained in the monitor. For more information about applying an override, see Using Classes and Groups for Overrides in Operations Manager.
If the Overrides button is not available, make sure you have selected a monitor and not a container object in the Monitors pane.
Click to place a check mark in the Override column next to each parameter that you want to override. The Override Value can now be edited. Change the value in Override Value to the value you want the parameter to use.
Either select a management pack from the Select destination management pack list or create a new unsealed management pack by clicking New. For more information about selecting a destination management pack, see Creating a Management Pack for Overrides.
When you complete your changes, click OK.
