How to Create an Override for a Diagnostic
Applies To: Operations Manager 2007 R2, Operations Manager 2007 SP1, System Center Operations Manager 2007
You can create an override for a property or configuration parameter for a diagnostic. A property override changes the default value of a diagnostic property, and a configuration override changes the default value of a custom configuration setting for a diagnostic. If you want to create an override for a diagnostic, use the ManagementPackDiagnosticPropertyOverride or ManagementPackDiagnosticConfigurationOverride class. These classes are derived from the ManagementPackDiagnosticOverride class.
Only the Enabled property can be overridden for diagnostics. To figure out which parameters can be overridden, you must look at the definition of the diagnostic in the Management Pack that defines the diagnostic. All the parameters that can be overridden are defined in the OverrideableParameters element of the diagnostic. You can also call the GetOverrideableParameters method to get the list of parameters programmatically.
The following example creates an override for the Enabled property of a diagnostic.
