CloudDBA provides the performance trends feature that allows you to monitor the basic performance metrics and corresponding performance trends of an ApsaraDB for Redis instance within a specified period of time. The performance trends include the CPU utilization, memory usage, queries per second (QPS), total number of connections, response time, network traffic, and key hit ratio.


  1. Log on to the ApsaraDB for Redis console and go to the Instances page. In the top navigation bar, select the region in which the instance is deployed. Then, find the instance and click the instance ID.
  2. In the left-side navigation pane, choose CloudDBA > Performance Trends.
  3. Use the following methods to view performance trends:
    redis-clouddba-Methods to view performance trends
    • Performance Trends

      On the Performance Trends tab, specify a time range, select more metrics, and then click Search.

      • You can select a specific node for a read/write splitting or cluster instance.
      • By default, Correlation is enabled. If you move the pointer over the CPU chart to view the CPU metric of the instance at 09:00, other charts also display other metrics of the instance at 09:00.
      • Click Definition in the upper-left corner of each metric chart to view the definition of the metric and click Details in the upper-right corner of each metric chart to obtain a larger view of the metric chart.
    • Performance Trend Comparison

      To compare the performance trends within two periods of time, click the Performance Trend Comparison tab, specify two periods of time, select more metrics, and then click Search.

    • Custom Chart

      The preceding two methods display the basic performance metrics of an ApsaraDB for Redis instance. If you want to display only some basic metrics, you can configure custom performance trend charts. For more information, see Add a custom performance trend chart.
