# DisassociateApplicationStatusCheck
<a name="API_DisassociateApplicationStatusCheck"></a>

Disassociates an application status check from instances or [tags](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html). After disassociation, health monitoring stops for the affected instances. The following rules apply:
+ You must specify either `TargetTagAssociations` or `InstanceIds`, but not both. Specifying both results in an `InvalidParameterCombination` error.
+ The application status check must already exist and belong to your account.
+ Tag keys must not be blank.

## Request Parameters
<a name="API_DisassociateApplicationStatusCheck_RequestParameters"></a>

The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see [Common Query Parameters](CommonParameters.md).

 **ApplicationStatusCheckId**   
The ID of the application status check to disassociate.  
Type: String  
Required: Yes

 **ClientToken**   
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. For more information, see [Ensuring idempotency](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/Run_Instance_Idempotency.html).  
Type: String  
Required: No

 **DryRun**   
Checks whether you have the required permissions for the operation, 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`.  
Type: Boolean

The IDs of the instances to disassociate from the application status check.  
Type: Array of strings  
Required: No

 **TargetTagAssociation.N**   
The [tags](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html) to disassociate from the application status check. Specify the same key-value pairs that were used during association.
