Configuring automatic O&M for system events

You can configure automatic O&M actions for an instance in the instance maintenance settings, which means the default system response action when the instance encounters a fault risk. For example, when an unexpected O&M event occurs, the system automatically restarts the instance or keeps the instance shut down.

tip

This feature is in Beta. If you need a trial, please contact your account manager.

Prerequisite

Currently, this feature only supports certain instance type families. For details, refer to Supported event types and actions.

Procedure

In the left-side navigation pane, select "Instances & Images > Images". The Instances page appears.

In the top menu bar, select the project and region of the target instance.

Select "... > Operations and troubleshooting > Instance maintenance property" in the "Actions" column on the right side of the target instance.

In the pop-up window, select the default maintenance action to be performed when the instance triggers the corresponding event.

tip

The maintenance action differs based on whether the instance is of the Local SSD type. Please refer to the actual display.

Click "Confirm" to complete the configuration.

tip

If the currently selected instance is the same as that before the change, the "Confirm" button is gray. This means that no O&M configuration is needed for this instance.

Supported event types and actions

The following table lists the event types currently supported for O&M configuration and their processing actions.

Event type	Description	Supported action	Supported instance types	Description
SystemFailure.Reboot	The instance is restarted due to system failures	Automatically restart the instance Automatically redeploy the instance Keep the instance in a shutdown status	Local SSD Big Data HPC-optimized	"Automatically restart the instance" is the default action. For details of action processes and actions you need to perform, refer to Querying and responding to the "System failure instance restart" events.
SystemFailure.Redeploy	The instance is redeployed due to system failures	Redeploy the instance and keep its original status Redeploy the instance and shut it down	All instance types provided by VolcanoEngine	"Redeploy the instance and keep its original status" is the default action. If an instance does not meet the requirements for automatic evacuation, it automatically restarts together with its host machine (physical machine). For details of action processes and actions you need to perform, refer to Querying and responding to the "Redeployment due to instances of system failure" events.
SystemFailure.Stop	The instance is stopped due to system failures	Redeploy the instance and shut it down	General-purpose Compute-optimized (excluding RDMA instances) Memory-optimized	"Redeploy the instance and shut it down" is the default action.
