You can use Operations Manager class libraries to programmatically generate and insert custom event and performance data into the Operations Manager database on behalf of specific monitoring objects.

Example

Example 1—Generating Event Data

This example demonstrates how to generate event data and insert it into the Operations Manager database on behalf of the monitoring object for an instance of SQL Server 2005 Database Engine on an agent-managed computer.

			Dim mg As ManagementGroup = New ManagementGroup("localhost")

			' Define the name of the agent-managed computer that was manually installed.
			Dim fullAgentName As String = "EnterFullyQualifiedAgentNameHere"
			Console.WriteLine("Inserting custom event for " + fullAgentName)

			Dim monitoringEvent As CustomMonitoringEvent = _
			 New CustomMonitoringEvent("EventPublisherName", 187)
			monitoringEvent.Channel = "Application"
			monitoringEvent.LoggingComputer = "AnyMachine"
			monitoringEvent.Message = New CustomMonitoringEventMessage("Sample Event Message.")
			monitoringEvent.User = "AnyUser"
			monitoringEvent.LevelId = 4
			' 1-Error, 2-Warning, 4-Information, 8-Success Audit, 16-Failure Audit.

			Dim query As String = "Name = 'Microsoft.SQLServer.DBEngine'"
			' Get the SQL Server Database Engine monitoring class.
			Dim DBEngineClassCriteria As MonitoringClassCriteria = New MonitoringClassCriteria(query)
			Dim classes As ReadOnlyCollection(Of MonitoringClass) = _
				mg.GetMonitoringClasses(DBEngineClassCriteria)
			If (classes.Count <> 1) Then
				Throw New InvalidOperationException("Expected one monitoring class with: " & query)
			End If

			' Get the SQL Server Database Engine monitoring object for the specified computer.

				End If

				MOIndex = MOIndex + 1
			Next

			If (MOIndex > SQLDBEngines.Count - 1) Then
				Throw New InvalidOperationException( _
					"The monitoring object for the agent's database engine was not found.")
			End If

			' Insert the event in the Operations Manager database.
			SQLDBEngines(MOIndex).InsertCustomMonitoringEvent(monitoringEvent)

			Console.WriteLine("Successfully inserted custom event.")
		End Function
	End Class

			Dim minValue As Integer = 100
			Dim maxValue As Integer = 200
			Dim timeSpanMins As Integer = 3
			Dim intervalSecs As Integer = 30

			Dim numberOfData As Integer = CInt((timeSpanMins * 60) / intervalSecs)
			Dim variation As Integer = maxValue - minValue
			Dim random As Random = New Random()

			' Get the SQL Server database-engine monitoring class.
			Dim DBEngineClassCriteria As MonitoringClassCriteria = New MonitoringClassCriteria(query)
			Dim classes As ReadOnlyCollection(Of MonitoringClass) = _
				mg.GetMonitoringClasses(DBEngineClassCriteria)
			If (classes.Count <> 1) Then
				Throw New InvalidOperationException("Expected one monitoring class with: " & query)
			End If

			' Get the database-engine monitoring object for the specified computer.
			Dim SQLDBEngines As ReadOnlyCollection(Of MonitoringObject) = _
				mg.GetMonitoringObjects(classes(0))
			Dim MOIndex As Integer = 0

			For Each DBEngine As MonitoringObject In SQLDBEngines

				' Find the monitoring object for a specific agent-managed computer.
				If (DBEngine.Path.Equals(fullAgentName)) Then
					Exit For
				End If
				MOIndex += 1

			Next

			If (MOIndex > SQLDBEngines.Count - 1) Then
				Throw New InvalidOperationException( _
					"The monitoring object for the agent's database engine was not found.")
			End If

			' Insert the performance data.
			Dim i As Integer
			For i = 0 To numberOfData Step 1

				' Generate the random data.
				Dim value As Double = (random.NextDouble() * variation) + minValue
