These metrics (for example, sustained activity or spikes in activity relative to the baseline performance) help you understand how busy a resource is and whether the level of activity is abnormal. The second type of metric enables further diagnosis of a problem by analyzing the number of backlogged requests that are waiting for the resource to become available.
