RightSizing (Recommend specifications)

Right Sizing Recommended Specifications

This function recommends appropriate specifications (downsizing or upsizing) based on resource monitoring data.

On 2025-09-22, AWS ElastiCache optimal specification recommendations and Azure OpenAI optimization features were added.

• Cache

  • As the cost of using AWS ElastiCache increases, the importance of cost optimization has increased, and appropriate specification features have been added.

  • Recommended in the same way as server/database

• AI

  • As Azure OpenAI usage grows, the need for optimization grows, so optimization features have been added.

  • Please refer to the document below for detailed guide.

As of 2024-09-26, the detection criteria for recommended appropriate specifications have been improved.

CloudXper has been improved to provide as many recommendations as possible based on the data it has.

• Improvements

  1. Changed from a recommended designated data source to a preferred data source recommendation method.(Server only)

     • Existing: If the data source for the detection criteria was not recommended (insufficient data, no data (CMS not installed)), appropriate specifications were not recommended.

       1. EX) Select data source “CMS”, if CMS agent is not installed on the server → “CMS not installed” is displayed.

     • Change: If the priority data source for the detection criteria is not recommended (insufficient data, no data (CMS not installed)), recommendations will be made through other data sources.

       1. EX) First, select the data source “CMS”. If the CMS agent is not installed on the server but CSP data can be recommended, it is recommended.
          
          

  2. We have relaxed the data insufficiency criteria and enabled you to directly set the data insufficiency criteria (operating rate within the analysis period).

     • Existing: Only the analysis period can be set, and the operating rate cannot be set, so it is recommended only when there is data of “80%” or more according to the default condition or “20%” or more depending on the setting.

       1. EX) Even if CPU data is “90%” and MEM data is “50%” within 93 days, recommendation is not possible due to “insufficient data”.

     • Change: You can now directly set the operating rate within the analysis period, and the basic condition has been changed to recommend when it exists at 20% or more within 93 days.

       1. EX) Even if CPU data is “30%” and Memory data is not present (Memory Agent not installed), appropriate specifications can be recommended based on CPU data.
          
          

  3. Detection criteria conditions have been removed. Conditions such as "CPU" and "MEM" have been removed, and the default condition has been fixed to "OR."

     • Existing: In case of “AND” condition, it was recommended that both CPU and Memory should have the same condition.

       1. EX) CPU: “Upsizing” condition, Memory: Normal → Displayed as Normal

     • Change: “CPU”, “MEM” conditions are gone and default “OR” condition works.

       1. EX) CPU: “Upsizing” condition, Memory: Normal → Displayed as “Upsizing”

       2. caution : Since the “Upsizing” condition has a higher priority than the downsizing condition, if there is an “Upsizing” recommendation indicator, it will be displayed as “Upsizing”.

          1. EX) CPU: “Upsizing” condition, Memory: “Downsizing” condition → Displayed as “Upsizing”
