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

 ** [LookbackWindow](#API_UpdateRetrainingScheduler_RequestSyntax) **   <a name="LookoutForEquipment-UpdateRetrainingScheduler-request-LookbackWindow"></a>
The number of past days of data that will be used for retraining.  
Type: String  
Pattern: `^P180D$|^P360D$|^P540D$|^P720D$`   
Required: No

 ** [ModelName](#API_UpdateRetrainingScheduler_RequestSyntax) **   <a name="LookoutForEquipment-UpdateRetrainingScheduler-request-ModelName"></a>
The name of the model whose retraining scheduler you want to update.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 200.  
Pattern: `^[0-9a-zA-Z_-]{1,200}$`   
Required: Yes

 ** [PromoteMode](#API_UpdateRetrainingScheduler_RequestSyntax) **   <a name="LookoutForEquipment-UpdateRetrainingScheduler-request-PromoteMode"></a>
Indicates how the service will use new models. In `MANAGED` mode, new models will automatically be used for inference if they have better performance than the current model. In `MANUAL` mode, the new models will not be used [until they are manually activated](https://docs.aws.amazon.com/lookout-for-equipment/latest/ug/versioning-model.html#model-activation).

Valid Values: `MANAGED | MANUAL`   
Required: No

 ** [RetrainingFrequency](#API_UpdateRetrainingScheduler_RequestSyntax) **   <a name="LookoutForEquipment-UpdateRetrainingScheduler-request-RetrainingFrequency"></a>
This parameter uses the [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601#Durations) standard to set the frequency at which you want retraining to occur in terms of Years, Months, and/or Days (note: other parameters like Time are not currently supported). The minimum value is 30 days (P30D) and the maximum value is 1 year (P1Y). For example, the following values are valid:  
+ P3M15D – Every 3 months and 15 days
+ P2M – Every 2 months
+ P150D – Every 150 days
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 10.  
Pattern: `^P(\dY)?(\d{1,2}M)?(\d{1,3}D)?$`   
Required: No

 ** [RetrainingStartDate](#API_UpdateRetrainingScheduler_RequestSyntax) **   <a name="LookoutForEquipment-UpdateRetrainingScheduler-request-RetrainingStartDate"></a>
The start date for the retraining scheduler. Lookout for Equipment truncates the time you provide to the nearest UTC day.  
Type: Timestamp
