CloudDBA allows you to view the performance metrics of ApsaraDB for Redis instances in real time. The performance metrics include information about CPU utilization, memory usage, queries per second (QPS), network traffic, servers, keys, clients, and connections.

Prerequisites

The instance is of Community Edition or Enhanced Edition (Performance-enhanced instances).

Procedure

  1. Log on to the ApsaraDB for Redis console.
  2. On the top of the page, select the region where the instance is deployed.
  3. On the Instance List page, click the Instance ID of the instance.
  4. In the left-side navigation pane, choose CloudDBA > Real-time Performance.
  5. You can view Real-time performance of global nodes and Real-time performance.
    • Real-time performance of global nodes

      The Real-time performance of global nodes page displays information about CPU utilization, memory usage, QPS, network traffic, and keys of each node in real time.

      Note Only read/write splitting instances and cluster instances support this feature.
    • Real-time performance
      Note
      • To view the metrics for read/write splitting instances and cluster instances, you can select a specific node.
      • To view performance changes in real time, the metrics are automatically updated every 5 seconds. The remaining updating times are displayed in the upper-right corner. To stop updating the performance metrics, you can click Pause.

      On the top of the page, performance metrics are displayed in real time. The metrics include information about the server, keys, memory, clients, and connections.

      Detailed performance metrics are displayed in Real-time Charts and Real-time Tables.

      Pattern Description
      Real-time Charts

      Displays real-time performance metrics of an instance in curve charts, such as key information, key hit information, key hit ratio, CPU utilization, memory information, QPS, and network traffic.
