Redis Showlog Command

Redis Server

Redis slowlog is a log system used by Redis to record query execution time.

Query execution time refers to the time consumed by executing a query command alone, excluding IO operations such as client response (talking) and sending replies.

Additionally, the slow log is stored in memory, and the read and write speed is very fast, so you can use it with confidence without worrying about slowing down Redis due to the opening of slow log.

Syntax

The basic syntax of the redis slowlog command is as follows:

redis　127.0.0.1:6379> SLOWLOG subcommand [argument]

Available Version

>= 2.2.12
