DescribeInstanceStatus

Describes the status of the specified instances or all of your instances. By default, only running instances are described, unless you specifically indicate to return the status of all instances.

Instance status includes the following components:

  • Status checks - Amazon EC2 performs status checks on running EC2 instances to identify hardware and software issues. For more information, see Status checks for your instances and Troubleshoot instances with failed status checks in the Amazon EC2 User Guide.

  • Scheduled events - Amazon EC2 can schedule events (such as reboot, stop, or terminate) for your instances related to hardware issues, software updates, or system maintenance. For more information, see Scheduled events for your instances in the Amazon EC2 User Guide.

  • Instance state - You can manage your instances from the moment you launch them through their termination. For more information, see Instance lifecycle in the Amazon EC2 User Guide.

Note

The order of the elements in the response, including those within nested structures, might vary. Applications should not assume the elements appear in a particular order.

Request Parameters

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.

DryRun

Checks whether you have the required permissions for the operation, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

Type: Boolean

Required: No

Filter.N

The filters.

  • availability-zone - The Availability Zone of the instance.

  • event.code - The code for the scheduled event (instance-reboot | system-reboot | system-maintenance | instance-retirement | instance-stop).

  • event.description - A description of the event.

  • event.instance-event-id - The ID of the event whose date and time you are modifying.

  • event.not-after - The latest end time for the scheduled event (for example, 2014-09-15T17:15:20.000Z).

  • event.not-before - The earliest start time for the scheduled event (for example, 2014-09-15T17:15:20.000Z).

  • event.not-before-deadline - The deadline for starting the event (for example, 2014-09-15T17:15:20.000Z).

  • instance-state-code - The code for the instance state, as a 16-bit unsigned integer. The high byte is used for internal purposes and should be ignored. The low byte is set based on the state represented. The valid values are 0 (pending), 16 (running), 32 (shutting-down), 48 (terminated), 64 (stopping), and 80 (stopped).

  • instance-state-name - The state of the instance (pending | running | shutting-down | terminated | stopping | stopped).

  • instance-status.reachability - Filters on instance status where the name is reachability (passed | failed | initializing | insufficient-data).

  • instance-status.status - The status of the instance (ok | impaired | initializing | insufficient-data | not-applicable).

  • system-status.reachability - Filters on system status where the name is reachability (passed | failed | initializing | insufficient-data).

  • system-status.status - The system status of the instance (ok | impaired | initializing | insufficient-data | not-applicable).

  • attached-ebs-status.status - The status of the attached EBS volume for the instance (ok | impaired | initializing | insufficient-data | not-applicable).

Type: Array of Filter objects

Required: No

IncludeAllInstances

When true, includes the health status for all instances. When false, includes the health status for running instances only.

Default: false

Type: Boolean

Required: No

InstanceId.N

The instance IDs.

Default: Describes all your instances.

Constraints: Maximum 100 explicitly specified instance IDs.

Type: Array of strings

Required: No

MaxResults

The maximum number of items to return for this request. To get the next page of items, make another request with the token returned in the output. For more information, see Pagination.

You cannot specify this parameter and the instance IDs parameter in the same request.

Type: Integer

Required: No

NextToken

The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.

Type: String

Required: No

Response Elements

The following elements are returned by the service.

instanceStatusSet

Information about the status of the instances.

Type: Array of InstanceStatus objects

nextToken

The token to include in another request to get the next page of items. This value is null when there are no more items to return.

Type: String

requestId

The ID of the request.

Type: String

Errors

For information about the errors that are common to all actions, see Common client error codes.
