Redis slow query log is a feature used to log commands with an execution time over the specified threshold. When the execution time of a command executed by Redis exceeds the preset time limit, a slow query log will record the relevant information of the command for subsequent analysis and performance optimization. The management console provides a function for querying Redis slow query logs. The function can query current slow query logs and historical slow query logs.
For details about the slow statement commands involved in the query results, please go to the Redis official website.
Note: You can modify the slow query log threshold by modifying the slowlog-log-slower-than parameter. See Modifying Instance Configuration Parameters.
