How to Create an Override for a Recovery

System Center

Updated: May 22, 2009

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 recovery. A property override changes the default value of a recovery property, and a configuration override changes the default value of a custom configuration setting for the recovery. If you want to create an override for a recovery, use the ManagementPackRecoveryPropertyOverride or ManagementPackRecoveryConfigurationOverride class. These classes are derived from the ManagementPackRecoveryOverride class.

Only the Enabled property can be overridden for recoveries. To figure out which parameters can be overridden, you must look at the definition of the recovery in the Management Pack that defines the recovery. All the parameters that can be overridden are defined in the OverrideableParameters element of the recovery. 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 recovery.

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Text;
using Microsoft.EnterpriseManagement;
using Microsoft.EnterpriseManagement.Administration;
using Microsoft.EnterpriseManagement.Common;
using Microsoft.EnterpriseManagement.Configuration;
using Microsoft.EnterpriseManagement.Monitoring;

namespace SDKSamples
{
    class Program
    {
        //---------------------------------------------------------------------
        static void Main(string[] args)
        {
            ManagementGroup                             mg;
            ManagementPack                              mp;
            MonitoringClassCriteria                     monitoringClassCriteria;
            MonitoringClass                             monitoringClass;
            MonitoringRecoveryCriteria                  recoveryCriteria;
            MonitoringRecovery                          recovery;
            ManagementPackRecoveryPropertyOverride      recoveryOverride;

            mg = new ManagementGroup("localhost");

            mp = mg.GetManagementPacks("OverrideTestMP")[0];

            monitoringClassCriteria = new MonitoringClassCriteria("Name='Microsoft.SystemCenter.HealthServiceWatcher'");

            monitoringClass = mg.GetMonitoringClasses(monitoringClassCriteria)[0];

            recoveryCriteria = new MonitoringRecoveryCriteria("Name='Microsoft.SystemCenter.HealthService.Recovery.AutoReinstallAgent'");

            recovery = mg.GetMonitoringRecoveries(recoveryCriteria)[0];

            recoveryOverride = new ManagementPackRecoveryPropertyOverride(mp, "SampleRecoveryOverride");

            recoveryOverride.Recovery     = recovery;
            recoveryOverride.Property     = ManagementPackWorkflowProperty.Enabled;
            recoveryOverride.Value        = "false";
            recoveryOverride.Context      = monitoringClass;
            recoveryOverride.DisplayName  = "SampleRecoveryOverride";

            mp.Verify();
            
            //Save the changes into the management pack.
            mp.AcceptChanges();
        }        
    }
}
