Auto-Healing

Expand all | Collapse all

The Auto-Healing functionality automatically detects problems that arise during the operation of a network service and takes the actions necessary to fix them. Such actions may include restarting non-operational components, replacing unavailable network resources, or redirecting traffic to virtual machines / instances that still work.

If this functionality is enabled for a network service, its components are restored automatically. If this functionality is disabled, restoring the components requires manual intervention by the administrator. By default, this functionality is enabled.

If necessary, you can use Auto-Healing for individual components of the network service, even if the functionality as a whole is disabled. To manage Auto-Healing, use the following instructions:
