-->The first step is to identify metrics and events that are reliable indicators of failure.

-->Metrics and events are data from IT elements that you monitor.

-->Metrics carry information about the availability, performance, and capacity of your IT elements.

-->The key to detecting outages is to select metrics and events values for monitoring.
