get-console-output¶

Description¶

Gets the console output for the specified instance. For Linux instances, the instance console output displays the exact console output that would normally be displayed on a physical monitor attached to a computer. For Windows instances, the instance console output includes the last three system event log errors.

By default, the console output returns buffered information that was posted shortly after an instance transition state (start, stop, reboot, or terminate). This information is available for at least one hour after the most recent post. Only the most recent 64 KB of console output is available.

You can optionally retrieve the latest serial console output at any time during the instance lifecycle. This option is supported on instance types that use the Nitro hypervisor.

For more information, see Instance console output in the Amazon EC2 User Guide .

Synopsis¶

  get-console-output
--instance-id <value>
[--dry-run | --no-dry-run]
[--latest | --no-latest]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--instance-id (string)

The ID of the instance.

--dry-run | --no-dry-run (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 .

--latest | --no-latest (boolean)

When enabled, retrieves the latest console output for the instance.

Default: disabled (false )

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To get the console output

The following get-console-output example gets the console output for the specified Linux instance.

aws ec2 get-console-output \
    --instance-id i-1234567890abcdef0

Output:

{
    "InstanceId": "i-1234567890abcdef0",
    "Timestamp": "2013-07-25T21:23:53.000Z",
    "Output": "..."
}

For more information, see Instance console output in the Amazon EC2 User Guide.

Example 2: To get the latest console output

The following get-console-output example gets the latest console output for the specified Linux instance.

aws ec2 get-console-output \
    --instance-id i-1234567890abcdef0 \
    --latest \
    --output text

Output:

i-1234567890abcdef0 [    0.000000] Command line: root=LABEL=/ console=tty1 console=ttyS0 selinux=0 nvme_core.io_timeout=4294967295

Output¶

InstanceId -> (string)

The ID of the instance.

Output -> (string)

The console output, base64-encoded. If you are using a command line tool, the tool decodes the output for you.
