Out of the box, we don't have any history of the actions being taken, i.e. any SNMP alert actions sent from Introscope or SMTP emails sent from Introscope.
However we do have the Alert Status Console Action. This is a window, when the Console Notification Action is created and activated, brings up an Alert Messages window and shows you what alerts have happened (caution or danger) and what alerts have been cleared (if the trigger is whenever severity changes is selected in the alert).
