Changes DescribeInstanceStatus now returns health information on EBS volumes attached to Nitro instances

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.

)
list
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).
(dict) --
A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.
If you specify multiple filters, the filters are joined with an AND, and the request returns only results that match all of the specified filters.
Name (string) --
The name of the filter. Filter names are case-sensitive.
Values (list) --
The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.
(string) --
list
The instance IDs.
Default: Describes all your instances.
Constraints: Maximum 100 explicitly specified instance IDs.
(string) --
integer
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.
string
The token returned from a previous paginated request. Pagination continues from the end of the items returned by the previous request.
boolean
Checks whether you have the required permissions for the action, 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.
boolean
When true, includes the health status for all instances. When false, includes the health status for running instances only.
Default: false

Response Structure
(dict) --
InstanceStatuses (list) --
Information about the status of the instances.
(dict) --
Describes the status of an instance.
AvailabilityZone (string) --
The Availability Zone of the instance.
OutpostArn (string) --
The Amazon Resource Name (ARN) of the Outpost.
Events (list) --
Any scheduled events associated with the instance.
(dict) --
Describes a scheduled event for an instance.
InstanceEventId (string) --
The ID of the event.
Code (string) --
The event code.
Description (string) --
A description of the event.
After a scheduled event is completed, it can still be described for up to a week. If the event has been completed, this description starts with the following text: [Completed].
NotAfter (datetime) --
The latest scheduled end time for the event.
NotBefore (datetime) --
The earliest scheduled start time for the event.
NotBeforeDeadline (datetime) --
The deadline for starting the event.
InstanceId (string) --
The ID of the instance.
InstanceState (dict) --
The intended state of the instance. DescribeInstanceStatus requires that an instance be in the running state.
Code (integer) --
The state of the instance as a 16-bit unsigned integer.
The high byte is all of the bits between 2^8 and (2^16)-1, which equals decimal values between 256 and 65,535. These numerical values are used for internal purposes and should be ignored.
The low byte is all of the bits between 2^0 and (2^8)-1, which equals decimal values between 0 and 255.
The valid values for instance-state-code will all be in the range of the low byte and they are:
0 : pending
16 : running
32 : shutting-down
48 : terminated
64 : stopping
80 : stopped
You can ignore the high byte value by zeroing out all of the bits above 2^8 or 256 in decimal.
