As we discussed, Oracle Enterprise Manager comes with a very comprehensive set of metrics that can monitor health and performance of your application servers, databases, Oracle VM Manager hosts, storage, and other components that constitute the cloud environment.

You can monitor several different types of events for these components. Usually you would be interested in monitoring an exceptional event or violation of a particular parameter for a component's performance. Oracle Enterprise Manager has a set of predefined thresholds to easily set up boundaries that will raise events when breached. There are two levels of severity for the alerts raised due to such anomalies:

  • Warning: While the threshold is breached, the component is still functional.

  • Critical: A critical threshold is breached and the component is either not functional or very near to a failure state. These types of events will require immediate preventive action.
