Aggregate services consist of one or more services, called subservices. A subservice is any service created in Enterprise Manager Grid Control. The availability, performance, and usage for the aggregate service depend on the availability, performance, and usage for the individual subservices comprising the service. Refer to About Services for more information on aggregate services.
Use this page to define the metrics used to measure the usage of your aggregate service. Usage metrics are used to measure the user demand or workload for the service. You can define usage metrics based on the metrics of one or more system components.
You can add usage metrics from single subservices, or based on statistical aggregations of more than one metric. Once you've selected usage metrics to use, you can set the thresholds used to trigger critical and warning alerts, or remove metrics you no longer want.
Note: If you delete a metric, this will impact the usage metrics of the aggregate or generic service that depend on this metric.
