An alert is defined as a list of actions triggered by a specific event. Actions can be used to notify a user about the problem, perform a diagnostic task, execute a corrective action/script or log event details. Alerts can be set on every type of event that is monitored by NetCrunch including: availability, performance and external events (Syslog, SNMP Trap, and Windows Event Log).

Alert Escalation and Correlation

Actions assigned to an event can be performed immediately or after some time if the event has not been cleared.

Most of the built-in events are correlated and when event condition changes they are automatically cleared.
