By using the Operations Manager class libraries, you can programmatically access operations data that is stored in the Operations Manager database (such as alert, event, and performance data). You can use criteria classes to narrow the search results when you are accessing operations data. For example, you can use the Microsoft.EnterpriseManagement.Monitoring.MonitoringEventCriteria class to narrow the search results for event data and the Microsoft.EnterpriseManagement.Monitoring.MonitoringAlertCriteria class to narrow the search results for alert data.
Example
The following example demonstrates how to display information about health service alerts that are stored in the Operations Manager database. The example also shows how to display information about stored events that are numbered 187.
