SnowDeviceManagement.Client.describe_device_ec2_instances(**kwargs)¶Checks the current state of the Amazon EC2 instances. The output is similar to describeDevice , but the results are sourced from the device cache in the Amazon Web Services Cloud and include a subset of the available fields.

Response Structure
(dict) --
instances (list) --
A list of structures containing information about each instance.
(dict) --
The details about the instance.
instance (dict) --
A structure containing details about the instance.
amiLaunchIndex (integer) --
The Amazon Machine Image (AMI) launch index, which you can use to find this instance in the launch group.
blockDeviceMappings (list) --
Any block device mapping entries for the instance.
(dict) --
The description of a block device mapping.
deviceName (string) --
The block device name.
ebs (dict) --
The parameters used to automatically set up Amazon Elastic Block Store (Amazon EBS) volumes when the instance is launched.
attachTime (datetime) --
When the attachment was initiated.
deleteOnTermination (boolean) --
A value that indicates whether the volume is deleted on instance termination.
status (string) --
The attachment state.
volumeId (string) --
The ID of the Amazon EBS volume.
cpuOptions (dict) --
The CPU options for the instance.
coreCount (integer) --
The number of cores that the CPU can use.
threadsPerCore (integer) --
The number of threads per core in the CPU.
createdAt (datetime) --
When the instance was created.
imageId (string) --
The ID of the AMI used to launch the instance.
instanceId (string) --
The ID of the instance.
instanceType (string) --
The instance type.
privateIpAddress (string) --
The private IPv4 address assigned to the instance.
publicIpAddress (string) --
The public IPv4 address assigned to the instance.
rootDeviceName (string) --
The device name of the root device volume (for example, /dev/sda1 ).
securityGroups (list) --
The security groups for the instance.
(dict) --
Information about the device's security group.
groupId (string) --
The security group ID.
groupName (string) --
The security group name.
state (dict) --
The description of the current state of an instance.
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 the instance state code are all in the range of the low byte. These values are:
0 : pending16 : running32 : shutting-down48 : terminated64 : stopping80 : stoppedYou can ignore the high byte value by zeroing out all of the bits above 2^8 or 256 in decimal.
name (string) --
The current state of the instance.
updatedAt (datetime) --
When the instance was last updated.
lastUpdatedAt (datetime) --
When the instance summary was last updated.
