Profile Descriptions

You can change the parameters in the profiles of some recommendations to tailor the operation of the recommendations to meet your requirements.

This section describes the following profiles.

Downsize Underutilized Compute Instances Profiles

The following profiles are available for the Downsize Underutilized Compute Instances recommendation type.

Average Method Profile Descriptions

If you choose the average method, the mean CPU utilization is used when evaluating compute instances. The profile options with the average method are:

  • Conservative (Average): The conservative profile identifies all compute instances that have had the following:

    • an average CPU utilization less than 5%
    • a maximum memory utilization less than 10%
    • a maximum network utilization less than 3%

    Supported VNICs are also considered. If a resize is recommended, the recommended core count has a projected average CPU utilization less than 10%.

  • Standard (Average): The standard profile identifies all compute instances that have had the following:

    • an average CPU utilization less than 10%
    • a maximum memory utilization less than 10%
    • a maximum network utilization less than 3%

    Supported VNICs are also considered. If a resize is recommended, the recommended core count has a projected average CPU utilization less than 20%.

  • Aggressive (Average): The Aggressive profile identifies all compute instances that have had the following:

    • an average CPU utilization less than 15%
    • a maximum memory utilization less than 10%.
    • a maximum network utilization less than 3%

    Supported VNICs are also considered. If a resize is recommended, the recommended core count has a projected average CPU utilization less than 30%.

P95 Method Profile Descriptions

  • If you choose the P95 method, a p-value of 95 is used to evaluate the CPU utilization threshold. The profile options with the P95 method are:

  • Conservative (P95): The conservative profile identifies all compute instances that have had the following:

    • a P95 CPU utilization less than 5%
    • a maximum memory utilization less than 10%
    • a maximum network utilization less than 3%

    Supported VNICs are also considered. If a resize is recommended, the recommended core count has a projected P95 CPU utilization less than 10%.

  • Standard (P95): The standard profile identifies all compute instances that have had the following:

    • a P95 CPU utilization less than 10%
    • a maximum memory utilization less than 10%
    • a maximum network utilization less than 3%

    Network throughput and supported VNICs are also considered. If a resize is recommended, the recommended core count has a projected P95 CPU utilization less than 20%.

  • Aggressive (P95): The aggressive profile identifies all compute instances that have had the following:

    • a P95 CPU utilization of less than 15%
    • a maximum memory utilization of less than 10%
    • a maximum network utilization less than 3%

  • Network throughput and supported VNICs are also considered. If a resize is recommended, the recommended core count has a projected P95 CPU utilization less than 30%.

Downsize Underutilized Load Balancers Profiles

The following profiles are available for the Downsize Underutilized Load Balancers recommendation type. All profile options use the average methodology.

Profile Descriptions

For these profiles, the PeakBandwidth metric is used. Peak bandwidth measures the maximum bandwidth per second used during the specified interval. For more details, see Load Balancer Metrics. Cloud Advisor pulls the metric every three hours and averages the values over the specified evaluation period.

  • Conservative: The conservative profile identifies all load balancers for which the average of the maximum values for peak bandwidth usage over the evaluation period is less than 85% of the minimum network bandwidth.

  • Standard: The standard profile identifies all load balancers for which the average of the maximum values for peak bandwidth usage over the evaluation period is less than 90% of the minimum network bandwidth.

  • Aggressive: The aggressive profile identifies all load balancers for which the average of the maximum values for peak bandwidth usage over the evaluation period is less than 95% of the minimum network bandwidth.

Rightsize Compute Instances Profiles

The following profiles are available for the Rightsize Compute Instances recommendation type.

Average Methodology Profile Descriptions

If you choose the average methodology, the mean CPU utilization is used when evaluating compute instances. The profile options with the average methodology are:

  • Conservative (Average): The conservative profile identifies all compute instances that have had both:

    • an average CPU utilization greater than 95% and
    • a maximum memory utilization greater than 95%

  • Standard (Average): The standard profile identifies all compute instances that have had both:

    • an average CPU utilization greater than 80% and
    • a maximum memory utilization greater than 80%

  • Aggressive (Average): The Aggressive profile identifies all compute instances that have had both:

    • an average CPU utilization greater than 60% and
    • a maximum memory utilization greater than 60%

P95 Methodology Profile Descriptions

If you choose the P95 methodology, a p-value of 95 is used to evaluate the CPU utilization threshold. The profile options with the P95 methodology are:

  • Conservative (P95): The conservative profile identifies all compute instances that have had both:

    • a P95 CPU utilization greater than 95% and
    • a maximum memory utilization greater than 95%

  • Standard (P95): The standard profile identifies all compute instances that have had both:

    • a P95 CPU utilization greater than 80% and
    • a maximum memory utilization greater than 80%

  • Aggressive (P95): The aggressive profile identifies all compute instances that have had both:

    • a P95 CPU utilization greater than 60% and
    • a maximum memory utilization greater than 60%
