Tair:Real-time performance

Procedure

1. Log on to the Tair console and go to the Instances page. In the top navigation bar, select the region in which the instance that you want to manage resides. Then, find the instance and click its 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

     • If your instance uses the read/write splitting or cluster architecture, you can select nodes whose performance metrics 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 the server, key, memory, client, and connection information. The client information refers to the number of connections.

     

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

     Pattern	Description
     Real-time Charts	Displays the real-time performance metrics of the instance in curve charts, such as the keys, key hit information, key hit rate, CPU utilization, memory usage, QPS, and network traffic.
     Real-time Tables	Displays the instance performance metrics in a table, including the key hit information, key hit rate, 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.
