Spot instance

Viewing interruption events for spot instances

When resource inventory is insufficient or the spot market price exceeds your bid price, the platform may reclaim your spot instance. Before being reclaimed, the instance triggers an instance interruption event. This topic describes how to view interruption events for spot instances.

tip

This topic is only about spot instance interruption events. If you want to learn more about event types, refer to Event type overview.

You can subscribe to event notifications. This allows you to receive instance release notifications via internal message, SMS, email, and other channels before the spot instance is interrupted (1 hour in advance for GPU instances and 5 minutes in advance for non-GPU instances).

On the "System Events" page, select the time period you want to query and view in the search bar as follows.

Method 1: Event type
