Synopsis

Calls the Amazon Elastic Compute Cloud (EC2) DescribeInstanceStatus API operation.

Syntax

Get-EC2InstanceStatus
-InstanceId <Object[]>
-Filter <Filter[]>
-IncludeAllInstance <Boolean>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-PassThru <SwitchParameter>
-NoAutoIteration <SwitchParameter>

Description

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 Troubleshooting Instances with Failed Status Checks in the Amazon Elastic Compute Cloud 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 Elastic Compute Cloud 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 Elastic Compute Cloud User Guide.


This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Parameters

-Filter <Filter[]>
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).
Required?False

Accept pipeline input?True (ByPropertyName)
AliasesFilters
-IncludeAllInstance <Boolean>
When true, includes the health status for all instances. When false, includes the health status for running instances only.Default: false
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesIncludeAllInstances
-InstanceId <Object[]>
The instance IDs.Default: Describes all your instances.Constraints: Maximum 100 explicitly specified instance IDs.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
AliasesInstanceIds
-MaxResult <Int32>
The maximum number of results to return in a single call. To retrieve the remaining results, make another call with the returned NextToken value. This value can be between 5 and 1000. You cannot specify this parameter and the instance IDs parameter in the same call.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
The token to retrieve the next page of results.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the InstanceId parameter. The -PassThru parameter is deprecated, use -Select '^InstanceId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'InstanceStatuses'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.DescribeInstanceStatusResponse). Specifying the name of a property of type Amazon.EC2.Model.DescribeInstanceStatusResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False

Outputs

This cmdlet returns a collection of Amazon.EC2.Model.InstanceStatus objects. The service call response (type Amazon.EC2.Model.DescribeInstanceStatusResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
