SLOW LOG ####################################The Redis Slow Log is a system to log queries that exceeded a specified#executiontime.The execution time does not include the I/O operations#liketalking with the client,sending the reply and so forth,#butjust the time needed to actually execute thecommand(this is the only#stageof command execution where the thread is blocked and can not serve#otherrequests in the meantime).##You can configure the slow log with two parameters:one tells Redis#whatis the execution time,in microseconds,to exceed in orderforthe#commandto get logged,and the other parameter is the length of the#slowlog.When a new command is logged the oldest one is removed from the#queueof logged commands.#The following time is expressed in microseconds,so1000000is equivalent#toone second.Note that a negative number disables the slow log,while#avalue of zero forces the logging of every command.slowlog-log-slower-than10000#There is no limit to this length.Just be
