CloudDBA provides the performance trends feature that allows you to monitor the basic performance metrics and corresponding performance trends of a Tair (Redis OSS-compatible) instance within a specified period of time. The performance metrics include the CPU utilization, memory usage, queries per second (QPS), total number of connections, response time, network traffic, and key hit ratio.
Procedure
Log on to the 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 its ID.
In the left-side navigation pane, choose .
Use the following methods to view performance trends.
Performance Trends
On the Performance Trends tab, specify a time range, select desired metrics, and then click Search.
NoteYou 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 the
icon in the upper-left corner of each metric chart to view the definition of the metric. 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 desired metrics, and then click Search.
Custom Charts
The preceding two methods display the basic performance metrics of an 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.
