The full list of status variables are listed in the contents on this page; most are described on this page, but some are described elsewhere:

See also the Full list of MariaDB options, system and status variables.

Use the SHOW STATUS statement to view status variables. This information also can be obtained using the mysqladmin extended-status command, or by querying the Information Schema GLOBAL_STATUS and SESSION_STATUS tables.

Issuing a FLUSH STATUS will reset many status variables to zero.
