Кроме использования запроса SHOW STATUS, который выводит информацию не упорядочено и вообще нечитаемо – можно воспользоваться утилитой mysqlreport.
Написана на Perl, домашняя страница тут>>>.
Установка:
# yum -y install mysqlreport
Или:
# wget http://hackmysql.com/scripts/mysqlreport # chmod +x mysqlreport
Запускаем:
# ./mysqlreport | less
