################################## SLOW LOG ###################################  \r\n# The Redis Slow Log is a system to log queries that exceeded a specified  \r\n# execution time. The execution time does not include the I\/O operations  \r\n# like talking with the client, sending the reply and so forth,  \r\n# but just the time needed to actually execute the command (this is the only  \r\n# stage of command execution where the thread is blocked and can not serve  \r\n# other requests in the meantime). \r\n# You can configure the slow log with two parameters: one tells Redis  \r\n# what is the execution time, in microseconds, to exceed in order for the  \r\n# command to get logged, and the other parameter is the length of the  \r\n# slow log. When a new command is logged the oldest one is removed from the  \r\n# queue of logged commands.   \r\n# The following time is expressed in microseconds, so 1000000 is equivalent  \r\n# to one second. Note that a negative number disables the slow log, while  \r\n# a value of zero forces the logging of every command.  \r\nslowlog-log-slower-than 10000   \r\n# There is no limit to this length. Just be aware that it will consume memory.  \r\n# You can reclaim memory used by the slow log with SLOWLOG RESET.  \r\nslowlog-max-len 128 \r\n<\/pre>\n
