PowerScale OneFS 9.5.0.0 API Reference Guide

Events and alerts

Events are individual occurrences or conditions that are related to the data workflow, maintenance operations, and hardware components of your cluster. An alert is a message that describes a change that has occurred in an event group.

Throughout OneFS, there are processes that are constantly monitoring and collecting information about 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.

At any point in time, you can view event groups to track situations occurring on your cluster. However, you can also create alerts that proactively notify you if there is a change in an event group.

For example, you can generate an alert when a new event is added to an event group, when an event group is resolved, or when the severity of an event group changes.

You can configure your cluster to only generate alerts for specific conditions or event groups, or during limited time periods.

Alerts are delivered through channels. You can configure a channel to determine who will receive the alert and when.
