MySQL Server Logs

MySQL 5.0 Reference Manual :: 5 MySQL Server Administration :: 5.2 MySQL Server Logs

MySQL has several different logs that can help you find out what is going on inside mysqld:

Log Type	Information Written to Log
The error log	Problems encountered starting, running, or stopping mysqld
The general query log	Established client connections and statements received from clients
The binary log	All statements that change data (also used for replication)
The slow query log	All queries that took more than long_query_time seconds to execute or didn't use indexes

By default, all log files are created in the mysqld data directory.
