LambdaFunctionRecommendation - AWS Compute Optimizer

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

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.

Note

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 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

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

Type: Array of LambdaFunctionMemoryRecommendationOption objects

Required: No

numberOfInvocations

The number of times your function code was applied during the look-back period.

Type: Long

Required: No

utilizationMetrics

An array of objects that describe the utilization metrics of the function.

Type: Array of LambdaFunctionUtilizationMetric objects

Required: No
