# LambdaFunctionRecommendation Describes an AWS Lambda function recommendation. ## Contents ** accountId ** The AWS account ID of the function. Type: String Required: No ** currentMemorySize ** The amount of memory, in MB, that's allocated to the current function. Type: Integer Required: No ** currentPerformanceRisk ** The risk of the current Lambda function not meeting the performance needs of its workloads. The higher the risk, the more likely the current Lambda function requires more memory. Type: String Valid Values: `VeryLow | Low | Medium | High` Required: No ** effectiveRecommendationPreferences ** Describes the effective recommendation preferences for Lambda functions. Type: [LambdaEffectiveRecommendationPreferences](API_LambdaEffectiveRecommendationPreferences.md) object Required: No ** finding ** The finding classification of the function. Findings for functions include: + ** `Optimized` ** — The function is correctly provisioned to run your workload based on its current configuration and its utilization history. This finding classification does not include finding reason codes. + ** `NotOptimized` ** — The function is performing at a higher level (over-provisioned) or at a lower level (under-provisioned) than required for your workload because its current configuration is not optimal. Over-provisioned resources might lead to unnecessary infrastructure cost, and under-provisioned resources might lead to poor application performance. This finding classification can include the `MemoryUnderprovisioned` and `MemoryUnderprovisioned` finding reason codes. + ** `Unavailable` ** — Compute Optimizer was unable to generate a recommendation for the function. This could be because the function has not accumulated sufficient metric data, or the function does not qualify for a recommendation. This finding classification can include the `InsufficientData` and `Inconclusive` finding reason codes. **Note** Functions with a finding of unavailable are not returned unless you specify the `filter` parameter with a value of `Unavailable` in your `GetLambdaFunctionRecommendations` request. Type: String Valid Values: `Optimized | NotOptimized | Unavailable` Required: No ** findingReasonCodes ** The reason for the finding classification of the function. Functions that have a finding classification of `Optimized` don't have a finding reason code. Finding reason codes for functions include: + ** `MemoryOverprovisioned` ** — The function is over-provisioned when its memory configuration can be sized down while still meeting the performance requirements of your workload. An over-provisioned function might lead to unnecessary infrastructure cost. This finding reason code is part of the `NotOptimized` finding classification. + ** `MemoryUnderprovisioned` ** — The function is under-provisioned when its memory configuration doesn't meet the performance requirements of the workload. An under-provisioned function might lead to poor application performance. This finding reason code is part of the `NotOptimized` finding classification. + ** `InsufficientData` ** — The function does not have sufficient metric data for Compute Optimizer to generate a recommendation. For more information, see the [Supported resources and requirements](https://docs.aws.amazon.com/compute-optimizer/latest/ug/requirements.html) in the * AWS Compute Optimizer User Guide*. This finding reason code is part of the `Unavailable` finding classification. + ** `Inconclusive` ** — The function does not qualify for a recommendation because Compute Optimizer cannot generate a recommendation with a high degree of confidence. This finding reason code is part of the `Unavailable` finding classification. Type: Array of strings Valid Values: `MemoryOverprovisioned | MemoryUnderprovisioned | InsufficientData | Inconclusive` Required: No ** functionArn ** The Amazon Resource Name (ARN) of the current function. Type: String Required: No ** functionVersion ** The version number of the current function. Type: String Required: No ** lastRefreshTimestamp ** The timestamp of when the function recommendation was last generated. Type: Timestamp Required: No ** lookbackPeriodInDays ** The number of days for which utilization metrics were analyzed for the function. Type: Double Required: No ** memorySizeRecommendationOptions ** An array of objects that describe the memory configuration recommendation options for the function. Type: Array of [LambdaFunctionMemoryRecommendationOption](API_LambdaFunctionMemoryRecommendationOption.md) objects Required: No ** numberOfInvocations ** The number of times your function code was applied during the look-back period. Type: Long Required: No ** tags ** A list of tags assigned to your Lambda function recommendations. Type: Array of [Tag](API_Tag.md) objects Required: No ** utilizationMetrics ** An array of objects that describe the utilization metrics of the function. Type: Array of [LambdaFunctionUtilizationMetric](API_LambdaFunctionUtilizationMetric.md) objects Required: No ## See Also For more information about using this API in one of the language-specific AWS SDKs, see the following: + [AWS SDK for C\$1\$1](https://docs.aws.amazon.com/goto/SdkForCpp/compute-optimizer-2019-11-01/LambdaFunctionRecommendation) + [AWS SDK for Java V2](https://docs.aws.amazon.com/goto/SdkForJavaV2/compute-optimizer-2019-11-01/LambdaFunctionRecommendation) + [AWS SDK for Ruby V3](https://docs.aws.amazon.com/goto/SdkForRubyV3/compute-optimizer-2019-11-01/LambdaFunctionRecommendation)
