An array of objects that describe function recommendations.
(dict) --
Describes an AWS Lambda function recommendation.
functionArn (string) --
The Amazon Resource Name (ARN) of the current function.
functionVersion (string) --
The version number of the current function.
accountId (string) --
The AWS account ID of the function.
currentMemorySize (integer) --
The amount of memory, in MB, that's allocated to the current function.
numberOfInvocations (integer) --
The number of times your function code was executed during the look-back period.
utilizationMetrics (list) --
An array of objects that describe the utilization metrics of the function.
(dict) --
Describes a utilization metric of an AWS Lambda function.

The name of the utilization metric.
statistic (string) --
The statistic of the utilization metric.
value (float) --
The value of the utilization metric.
lookbackPeriodInDays (float) --
The number of days for which utilization metrics were analyzed for the function.
lastRefreshTimestamp (datetime) --
The time stamp of when the function recommendation was last refreshed.
finding (string) --
The finding classification for 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.
findingReasonCodes (list) --
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.
Reason codes 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, or there was an internal error. This finding reason code is part of the Unavailable finding classification.
