ApsaraDB for Redis:View performance metrics in real time

Procedure

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 > Real-time Performance.
3. You can view Global Real-time Node Performance and Real-time Performance.
   • Global Real-time Node Performance

     The Global Real-time Node Performance tab displays metrics such as CPU utilization, memory usage, QPS, network traffic, and keys of each node in the instance in real time.

     Note Only read/write splitting instances and cluster instances support this feature.
   • Real-time Performance
     Note

     • For a read/write splitting instance or cluster instance, you can select a specific node that you want to view.
     • To allow you to view performance changes in real time, the metrics are automatically refreshed every 5 seconds. The available refreshes are displayed in the upper-right corner. To stop updating the performance metrics, you can click Pause.

     In the upper part of the page, performance metrics are displayed in real time. The metrics include servers, keys, memory usage, clients, and connections.

     

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

     Pattern	Description
     Real-time Charts	Displays the real-time performance metrics of the instance in curve charts, such as keys, key hit information, key hit ratio, CPU utilization, memory usage, QPS, and network traffic.
     Real-time Tables	Displays the instance performance metrics in tables, including key hit information, key hit ratio, QPS, memory usage, CPU utilization, network traffic, clients, and connections. The table can display up to 999 records. A new record is added to the table every 5 seconds.
