          Space Diagnosis

          Overview

          The space diagnosis includes two modules: space overview and data space. The space overview trend facilitates you to decide whether to change the configuration of the instance. The data space of the datasheet allows you to understand the space usage and datasheet fragmentation.

          Interpretation of Terms

          Metrics Meanings Description
          Total storage space The current storage space of the instance, i.e., disk size. For a 2-core 4G 100GB instance, its total space is 100GB.
          Used storage space Used data storage space For a 2-core 4G 100GB instance, the used space is 80GB
          Average daily growth in the past week (Space at the collection time - space at this time before 7 days)/7 ——
          Days of storage space availability Available storage space/average daily growth in the past week ——
          Data space change trend Used data storage space/current storage space of the instance ——
          System space change trend Used system storage space/current storage space of the instance ——

          Instruction for Use

          1. When you enter the data space page, the datasheet data space analysis is triggered automatically. You can select the database you want to view according to your requirements.
          2. The data space details list supports sorting.

          Operation Guide

          1. Log in to Console of Baidu AI Cloud Database RDS.
          2. In the RDS console, select a MySQL dual-computer high-availability master instance and click the instance name to enter the Instance Details.
          3. On the "Baidu AI Cloud Database RDS Instance Details" page, click SmartDBA to show the module information.
          4. Click Space Diagnosis and select "Space Overview" or "Data Space" in the diagnosis type to view relevant information.
