Dell EMC Metro node 7.1 Events and Alerts Reference Guide

Alerts roll-up is the process of consolidating the alerts based on the circumstances that are possessed at the time of generation of platform alerts and at the time of moving the live alerts to historical alerts. As of now, the roll-up is applicable only for the platform alerts.

The roll-ups are at two different places:

Live alerts roll-up for platform alerts

The roll-up of alerts happens if there are multiple alerts that are generated for the same condition ID within a span of 30 sec interval. In 30 seconds window, the initial five events generate as many alerts, and the later events are rolled up and generate a single alert depicting the number of times the event occurred.

Closing of rolled-up alerts (automatically through system)-If the clear rolled-up alerts generate for these rolled-up alerts, then these rolled-up alerts can be closed. If system generated clear events are received more than five within the 30 seconds window, then clear roll-up alert is generated.

Alerts roll-up if the notifications service was down

If the notification service is down momentarily, and some events are generated gradually during that time, then on the service restart, it processes all the events, and the same roll-up logic is applied as the events are consumed through the service from broker within 30 seconds.
