ECS event notifications deliver real-time resource change signals, replacing SDK polling with event-driven automated O&M.
Event notification name
The name field in a notification identifies the event code in <resource type>:<event>:<status> format.
-
<resource type>: the ECS resource type. Example: Instance (ECS instances) and Disk (block storage devices).
-
<event>: the event name. Examples: SystemMaintenance.Reboot, StateChange, PreemptibleInstanceInterruption, DiskOperationCompleted, and CreateSnapshotCompleted.
-
<status>: the event status. Valid values: Overview.
NoteThe <status> field applies only to system events related to instances and block storage devices.
Event notification format
ECS sends notifications through the method you specify. The following example shows a default JSON notification for an instance state change event.
If your notification method supports format conversion, the notification may be in a different format.
