How to Create an Override for a Discovery
Applies To: System Center 2012 - Operations Manager
[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]
You can create an override for a property or configuration parameter for a discovery. A property override changes the default value of a discovery property, and a configuration override changes the default value of a custom configuration setting for a discovery. If you want to create an override for a discovery, use the ManagementPackDiscoveryPropertyOverride or ManagementPackDiscoveryConfigurationOverride class. These classes are derived from the ManagementPackDiscoveryOverride class.
Only the Enabled property can be overridden for discoveries. To figure out which parameters can be overridden, you must look at the definition of the discovery in the management pack that defines the discovery. All the parameters that can be overridden are defined in the OverrideableParameters element of the discovery. You can also call the ManagementPackDiscovery.GetOverrideableParameters method to get the list of parameters programmatically.
The following example creates an override for the Enabled property of a discovery.

ManagementPackDiscoveryPropertyOverride discoveryOverride;
mg = new ManagementGroup("localhost");
mp = mg.ManagementPacks.GetManagementPacks(new ManagementPackCriteria("Name='OverrideTestMP'"))[0];
classCriteria = new ManagementPackClassCriteria("Name='Microsoft.SQLServer.2005.DBEngine'");
monitoringClass = mg.EntityTypes.GetClasses(classCriteria)[0];
discoveryCriteria = new ManagementPackDiscoveryCriteria("Name='Microsoft.SQLServer.2005.DatabaseDiscoveryRule'");
discovery = mg.Monitoring.GetDiscoveries(discoveryCriteria)[0];
discoveryOverride = new ManagementPackDiscoveryPropertyOverride(mp, "SampleDiscoveryOverride");
discoveryOverride.Discovery = discovery;
discoveryOverride.Property = ManagementPackWorkflowProperty.Enabled;
discoveryOverride.Value = "false";
discoveryOverride.Context = monitoringClass;
discoveryOverride.DisplayName = "SampleDiscoveryOverride";
mp.Verify();
//Save the changes into the management pack.
mp.AcceptChanges();
}
