Image em_aud_activity_detailed.gif shows a detailed view of the Ready To Be Sent notifications page. From top to bottom, left to right, are the following components:
Statistics: Shows Last Known value, Average Value, High Value, Low Value, Warning Threshold, Critical Threshold, Occurrences Before Alert, and Corrective Action.
Metric Value is a time graph to the right of the Statistics area, showing how the notifications changed over a period of time. By default this is 24 hours, but you can change the setting by selecting from the View Data list in the upper right corner.
Alert History, which follows Statistics and Metric Value, shows a table that describes the history of alerts. It lists the Severity, Timestamp, and Message.
Following Alert History is Related Links, which contains a Compare Targets link.
