Event Management during a platform upgrade

During a platform upgrade, as of Istanbul, Event Management jobs whose Upgrade safe flag is marked as true remain running.

During an upgrade of the platform, the Event Management connectors are working and continue to retrieve events. The events are being processed, transformed to an alert using event rules and if there is a suitable alert action rule, a task is created. However, the impact calculation is not supported during the platform upgrade.
Note: Event Management jobs that started running before the platform upgrade commenced continue to run during the upgrade.
The following Event Management jobs remain running as their Upgrade safe flag is marked as true:
  • Connector execution job
  • Event Management - close flapping alerts
  • Event Management - close threshold alerts
  • Event Management - create/resolved incidents by alerts
  • Event Management - Maintenance Calculator
  • Event Management - process events
During the platform upgrade, all other Event Management jobs wait for the platform upgrade to finish.
Note: During an Event Management plugin upgrade, ALL Event Management jobs do NOT work.
