MonitoringAlert Class

Updated: April 16, 2012

Represents an Operations Manager monitoring alert. In Operations Manager, an alert is an item that indicates that a predefined situation has occurred on a monitored object. Alerts are defined by rules. Namespace: Microsoft.EnterpriseManagement.Monitoring
Assembly: Microsoft.EnterpriseManagement.OperationsManager (in Microsoft.EnterpriseManagement.OperationsManager.dll)Dim instance As MonitoringAlert <SerializableAttribute> _ Public Class MonitoringAlert Inherits OperationalDataObject[SerializableAttribute] public class MonitoringAlert : OperationalDataObject[SerializableAttribute] public ref class MonitoringAlert : public OperationalDataObject/** @attribute SerializableAttribute() */ public class MonitoringAlert extends OperationalDataObjectSerializableAttribute public class MonitoringAlert extends OperationalDataObject

The following example shows how to get the Windows computers in a Management Group and display the health state and number of alerts for each computer.

	class Program
		static void Main(string[] args)

			ManagementGroup managementGroup = new ManagementGroup("localhost");
			ManagementPackClass windowsComputerClass = managementGroup.EntityTypes.GetClass(SystemMonitoringClass.WindowsComputer);

			List<PartialMonitoringObject> windowsComputerObjects = new List<PartialMonitoringObject>();
			IObjectReader<PartialMonitoringObject> reader = managementGroup.EntityObjects.GetObjectReader<PartialMonitoringObject>(windowsComputerClass, ObjectQueryOptions.Default);

			foreach (PartialMonitoringObject windowsComputerObject in windowsComputerObjects)
				ReadOnlyCollection<MonitoringAlert> alerts;

				alerts = windowsComputerObject.GetMonitoringAlerts(

				Console.WriteLine("{0} - State: {1} - Number of alerts: {2}",

				foreach (MonitoringAlert alert in alerts)
					Console.WriteLine("{0}", alert.Name);

The MonitoringAlert class contains information about an alert in Operations Manager. Alerts are used to notify operators of problems. Alerts are driven by event processing rules or scripts. An alert tells you when something significant happened in one of your systems. You can monitor alerts to determine the significance of an alert and the corrective action to be taken.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
