      The Amazon Resource Name (ARN) of the current function.

      Returns:
      The Amazon Resource Name (ARN) of the current function.

    • functionVersion

      public final String functionVersion()

      The version number of the current function.

      Returns:
      The version number of the current function.

    • accountId

      public final String accountId()

      The Amazon Web Services account ID of the function.

      Returns:
      The Amazon Web Services account ID of the function.

    • currentMemorySize

      public final Integer currentMemorySize()

      The amount of memory, in MB, that's allocated to the current function.

      Returns:
      The amount of memory, in MB, that's allocated to the current function.

    • numberOfInvocations

      public final Long numberOfInvocations()

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

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

    • hasUtilizationMetrics

      public final boolean hasUtilizationMetrics()
      For responses, this returns true if the service returned a value for the UtilizationMetrics property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • utilizationMetrics

      public final List<LambdaFunctionUtilizationMetric> utilizationMetrics()

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

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasUtilizationMetrics() method.

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

    • lookbackPeriodInDays

      public final Double lookbackPeriodInDays()

      The number of days for which utilization metrics were analyzed for the function.

      Returns:
      The number of days for which utilization metrics were analyzed for the function.

    • lastRefreshTimestamp

      public final Instant lastRefreshTimestamp()

      The timestamp of when the function recommendation was last generated.

      Returns:
      The timestamp of when the function recommendation was last generated.

    • finding

      public final LambdaFunctionRecommendationFinding 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.

        Functions with a finding of unavailable are not returned unless you specify the filter parameter with a value of Unavailable in your GetLambdaFunctionRecommendations request.

      If the service returns an enum value that is not available in the current SDK version, finding will return LambdaFunctionRecommendationFinding.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from findingAsString().

      Returns:
      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.

        Functions with a finding of unavailable are not returned unless you specify the filter parameter with a value of Unavailable in your GetLambdaFunctionRecommendations request.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasFindingReasonCodes() method.
