Use DescribeInstanceStatus with an AWS SDK or CLI

To describe the status of an instance

The following describe-instance-status example describes the current status of the specified instance.

aws ec2 describe-instance-status \
    --instance-ids i-1234567890abcdef0

Output:

{
    "InstanceStatuses": [
        {
            "InstanceId": "i-1234567890abcdef0",
            "InstanceState": {
                "Code": 16,
                "Name": "running"
            },
            "AvailabilityZone": "us-east-1d",
            "SystemStatus": {
                "Status": "ok",
                "Details": [
                    {
                        "Status": "passed",
                        "Name": "reachability"
                    }
                ]
            },
            "InstanceStatus": {
                "Status": "ok",
                "Details": [
                    {
                        "Status": "passed",
                        "Name": "reachability"
                    }
                ]
            }
        }
    ]

Example 1: This example describes the status of the specified instance.

Get-EC2InstanceStatus -InstanceId i-12345678

Output:

SystemStatus     : Amazon.EC2.Model.InstanceStatusSummary

$status = Get-EC2InstanceStatus -InstanceId i-12345678
$status.InstanceState

Output:
