Throughout OneFS there are processes that are constantly monitoring and collecting information on cluster operations.
When the status of a component or operation changes, the change is captured as an event and placed into a priority queue at the kernel level.
Every event has two ID numbers that help to establish the context of the event:
- The event type ID identifies the type of event that has occurred.
- The event instance ID is a unique number that is specific to a particular occurrence of an event type. When an event is submitted to the kernel queue, an event instance ID is assigned. You can reference the instance ID to determine the exact time that an event occurred.
You can view individual events. However, you manage events and alerts at the event group level.
