Dell EMC Metro node 7.1 Events and Alerts Reference Guide

OPEN

It represents the state when an alert has been raised. When the alert is raised, the state remains open until the user closes or acknowledges it from the UI, or the system generates a clear event that represents the issue has been resolved.

CLOSED

The user can move an alert to closed state after resolving the issue, or the system generates a clear event that represents the issue has been resolved.

If the alert is closed from the UI, then its state changes to CLOSED, and the Last Updated time is updated but the severity remains the same.

If the platform alert is closed through a system-generated event, then its severity changes to CLEAR along with the state change to CLOSED, and the Last Updated time is updated.

The Operational Alerts are closed automatically after four hours. If node or director reboots, or NDU is performed within this four hours interval, then Operational Alerts remain open even after four hours.

The Hardware alerts state change to closed state after moving to historical alerts.

ACK

Once the user feels that the message has been checked and there are no functional consequences because of the issue, then the user can move an OPEN alert to the ACK state. Acknowledging an alert does not indicate that the issue has been resolved, but it means that the user is aware to bear the consequences caused through the underlying issue with that alert.
