How to Create an Override for a Rule
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 rule. A property override changes the default value of a rule property, and a configuration override changes the default value of a custom configuration setting for a rule. If you want to create an override for a rule, use the ManagementPackRulePropertyOverride or ManagementPackRuleConfigurationOverride class. These classes are derived from the ManagementPackRuleOverride class.
Only the Enabled property can be overridden for rules. To figure out which parameters can be overridden, you must look at the definition of the rule in the management pack that defines the rule. All the parameters that can be overridden are defined in the OverrideableParameters element of the rule. You can also call the ManagementPackRule.GetOverrideableParameters method to get the list of parameters programmatically.
The following example creates an override for the Enabled property of a rule:
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;
ManagementPackClassCriteria classCriteria;
ManagementPackClass monitoringClass;
ManagementPackRuleCriteria ruleCriteria;
ManagementPackRule rule;
ManagementPackRulePropertyOverride ruleOverride;
mg = new ManagementGroup("localhost");
mp = mg.ManagementPacks.GetManagementPacks(new ManagementPackCriteria("DisplayName='OverrideTestMP'"))[0];
classCriteria = new ManagementPackClassCriteria("Name='Microsoft.SQLServer.2005.Database'");
monitoringClass = mg.EntityTypes.GetClasses(classCriteria)[0];
ruleCriteria = new ManagementPackRuleCriteria("DisplayName='Collect Database Free Space (%)'");
rule = mg.Monitoring.GetRules(ruleCriteria)[0];
ruleOverride = new ManagementPackRulePropertyOverride(mp, "SampleRuleOverride");
ruleOverride.Rule = rule;
ruleOverride.Property = ManagementPackWorkflowProperty.Enabled;
ruleOverride.Value = "false";
ruleOverride.Context = monitoringClass;
ruleOverride.DisplayName = "SampleRuleOverride";
mp.Verify();
//Save the changes into the management pack.
mp.AcceptChanges();
}
}
