Type: Array of strings Required: No ** [filters](#API_GetAutoScalingGroupRecommendations_RequestSyntax) ** An array of objects to specify a filter that returns a more specific list of Auto Scaling group recommendations. Type: Array of [Filter](API_Filter.md) objects Required: No ** [maxResults](#API_GetAutoScalingGroupRecommendations_RequestSyntax) ** The maximum number of Auto Scaling group recommendations to return with a single request. To retrieve the remaining results, make another request with the returned `nextToken` value. Type: Integer Valid Range: Minimum value of 0. Maximum value of 1000. Required: No ** [nextToken](#API_GetAutoScalingGroupRecommendations_RequestSyntax) ** The token to advance to the next page of Auto Scaling group recommendations. Type: String Required: No ** [recommendationPreferences](#API_GetAutoScalingGroupRecommendations_RequestSyntax) ** An object to specify the preferences for the Auto Scaling group recommendations to return in the response. Type: [RecommendationPreferences](API_RecommendationPreferences.md) object Required: No ## Response Syntax ``` { "autoScalingGroupRecommendations": [ { "accountId": "string", "autoScalingGroupArn": "string", "autoScalingGroupName": "string", "currentConfiguration": { "allocationStrategy": "string", "desiredCapacity": number, "estimatedInstanceHourReductionPercentage": number, "instanceType": "string", "maxSize": number, "minSize": number, "mixedInstanceTypes": [ "string" ], "type": "string" }, "currentInstanceGpuInfo": { "gpus": [ { "gpuCount": number, "gpuMemorySizeInMiB": number } ] }, "currentPerformanceRisk": "string", "effectiveRecommendationPreferences": { "cpuVendorArchitectures": [ "string" ], "enhancedInfrastructureMetrics": "string", "externalMetricsPreference": { "source": "string" }, "inferredWorkloadTypes": "string", "lookBackPeriod": "string", "preferredResources": [ { "effectiveIncludeList": [ "string" ], "excludeList": [ "string" ], "includeList": [ "string" ], "name": "string" } ], "savingsEstimationMode": { "source": "string" }, "utilizationPreferences": [ { "metricName": "string", "metricParameters": { "headroom": "string", "threshold": "string" } } ] }, "finding": "string", "inferredWorkloadTypes": [ "string" ], "lastRefreshTimestamp": number, "lookBackPeriodInDays": number, "recommendationOptions": [ { "configuration": { "allocationStrategy": "string", "desiredCapacity": number, "estimatedInstanceHourReductionPercentage": number, "instanceType": "string", "maxSize": number, "minSize": number, "mixedInstanceTypes": [ "string" ], "type": "string" }, "instanceGpuInfo": { "gpus": [ { "gpuCount": number, "gpuMemorySizeInMiB": number } ] }, "migrationEffort": "string", "performanceRisk": number, "projectedUtilizationMetrics": [ { "name": "string", "statistic": "string", "value": number } ], "rank": number, "savingsOpportunity": { "estimatedMonthlySavings": { "currency": "string", "value": number }, "savingsOpportunityPercentage": number }, "savingsOpportunityAfterDiscounts": { "estimatedMonthlySavings": { "currency": "string", "value": number }, "savingsOpportunityPercentage": number } } ], "utilizationMetrics": [ { "name": "string", "statistic": "string", "value": number } ] } ], "errors": [ { "code": "string", "identifier": "string", "message": "string" } ], "nextToken": "string" } ``` ## Response Elements If the action is successful, the service sends back an HTTP 200 response.
