Describes the status of an Amazon Elastic Compute Cloud (Amazon EC2) instance. Instance status provides information about two types of scheduled events for an instance that may require your attention:
system-reboot or instance-reboot . System reboot commonly occurs if certain maintenance or upgrade operations require a reboot of the underlying host that supports an instance. Instance reboot commonly occurs if the instance must be rebooted, rather than the underlying host. Rebooting events include a scheduled start and end time. instance-retirement . Retirement commonly occurs when the underlying host is degraded and must be replaced. Retirement events include a scheduled start and end time. You're also notified by email if one of your instances is set to retiring. The email message indicates when your instance will be permanently retired. If your instance is permanently retired, it will not be restarted. You can avoid retirement by manually restarting your instance when its event code is instance-retirement . This ensures that your instance is started on a healthy host.
DescribeInstanceStatus returns information only for instances in the running state.
You can filter the results to return information only about instances that match criteria you specify. For example, you could get information about instances in a specific Availability Zone. You can specify multiple values for a filter (e.g., more than one Availability Zone). An instance must match at least one of the specified values for it to be included in the results.
You can specify multiple filters. An instance must match all the filters for it to be included in the results. If there's no match, no special message is returned; the response is simply empty.
You can use wildcards with the filter values: * matches zero or more characters, and ? matches exactly one character. You can escape special characters using a backslash before the character. For example, a value of \*amazon\?\\ searches for the literal string *amazon?\ .
The following filters are available:
availability-zone - Filter on an instance's availability zone. instance-state-name - Filter on the intended state of the instance, e.g., running. instance-state-code - Filter on the intended state code of the instance, e.g., 16. | |
