Im trying to to find  slow queries /etc/mysql/my.cnf the configuration- i

log_slow_queries                = /var/log/mysql/mysql-slow.log
long_query_time                 = 1
log-queries-not-using-indexes   = 1
(Im pretty new to DBA) from my understanding after readin about the 1 stands for second and from some reason the results in mysql-slow.log file have query time=0.0008 which for my understanding not suppose to be there.
from my understanding in the slow log file suppse to be queries the the query time that is more than 1 second.

If you only need those queries which are taking 1 or more seconds then disable log-queries-not-using-indexes option. When you have log-queries-not-using-indexes =1, your log will also contains those queries who are not using indexes regardless of seconds mentioned for long_query_time. Comment log-queries-not-using-indexes and restart MySQL.
