Description
Big key and hot key analysis consumes CPU resources. It is recommended to perform big key and hot key analysis during off-peak hours.
Before You Begin
A DCS Redis cluster version instance that has been successfully created and is running.
l When performing hot key analysis, you need to change maxmemory-polic to volatile-lfu in the instance configuration. See Modifying Instance Configuration Parameters.
Procedure
1. Log in to the Redis management console.
2. In the upper left corner of the management console, select the region where the instance is located.
3. On the instance list page, click the target instance name to go to the instance details page.
4. On the main menu, click metric monitoring and then click TOP KEY analysis on the metric monitoring page to view the results of big keys and hot keys analysis.
5. Click on history and check TOP KEY to perform an automatic scan to search for historical big keys and hot keys.
Note:
Checking TOP KEY for automatic scanning may have a performance impact in scenarios with heavy business volumes.
