NameDescription
CountNumber of binlog files.

Binary Log File CountThe binary log is a set of files that contain information about data modifications made by the MySQL server. It enables replication as well as point-in-time recovery, preventing data loss during a disaster recovery situation. It also enables you to review all alterations made to your database. However, binary logs can consume a very large amount of disk space and should be removed from a production server to free up space after they are no longer needed by the slaves connecting to this master server, and after they have been backed up.
