    Zabbix2.0 запросы к бд

    Заметил что запросы начинающиеся
    Code:
    SELECT DISTINCT t.triggerid, t.expression, td.name, t.description
    FROM triggers t, trigger_discovery td
    Идут все в Сopying to tmp table
    Из-за этого возрастает iowait сервера.
    Появляетя после включения обнаружения.
    Что я делаю не так?

      А версия какая мускуля?

      innodb_flush_log_at_trx_commit = 2

      innodb_file_per_table
      innodb_flush_method = O_DIRECT
      innodb_log_file_size = 512M
      innodb_log_buffer_size = 4M
      innodb_buffer_pool_size = 6G
      innodb_thread_concurrency =8

      Не в ту секцию запихали нужно в [mysqld], а не в [isamchk]

        Когда перенесете мускуль ругаться будет. Вообщем почитайте в инете как правильно применить innodb_log_file_size = 512M и innodb_file_per_table.

        Хотя можно сделать дамп и залить обратно или выполнить OPTIMIZE TABLE, это для per_file.
        Для второго нужно будет убить файл на который мускуль будет ругаться при старте

        Ну и на всякий случай сделайте резервную копию БД.

          Версия 5.5
          dotneft, innodb_file_per_table и так работает, он там в двух местах был, и в одно в верной секции. А вот innodb_log_file_size = 512M в неправильной секции, простой перенос не помогает, сервер не стартует. Надо читать как сдеалть и что это дает
          Во временную таблицу иедт сл запрос

                  какая конфигурация сервера? какой размер базы? и какая дисковая подсистема?

                    много. Я такого не делал даже на 4000npvs.

                    expire_logs_days = 10
                    зачем столько дней? оО

                      Не пинайте тапком, настраивал как мог, сколько советов спрашивал, но особо внятно никто не помог, так что буду рад любой помощи.
                      Сейчас забикс копошится с такими параметрами
                      Code:
                      Параметр	Значение	Детали
                      Zabbix сервер запущен	Да	localhost:10051
                      Количество узлов сети (под наблюдением/без наблюдения/шаблоны)	757	645 / 29 / 83
                      Количество элементов данных (активных/деактивированых/не поддерживаются)	195090	122155 / 72214 / 721
                      Количество триггеров (активированных/деактивированных)[проблема/неизвестно/ок]	26421	25923 / 498  [125 / 0 / 25798]
                      Количество пользователей (в сети)	38	1
                      Требуемое быстродействие сервера, новые значения в секунду	141.76	-
                      Как порекомендуете их изменить?
                      Размер БД порядка 10-20 гиг еще не устаканился, на 1.8 был размер 7-9G

                      Вчера выключил хаускипер (включал его для проверки утром) и выключил все правила обнаружения срзау стало легче.
                      Графики ниже, выключил все в около 18 00

                        Using this rule of thumb, calculate your innodb_log_file_size such that it's big enough to let InnoDB optimize its I/O, but not so big that recovery takes a long time.

                        почитал
                        Code:
                        mysql> SHOW engine innodb STATUS\G SELECT sleep(60); SHOW engine innodb STATUS\G
                        Log sequence number 1555194790770
                        1 row in set (0.00 sec)
                        
                        1 row in set (1 min 0.01 sec)
                        
                        Log sequence number 1555197733345
                        1 row in set (0.00 sec)
                        2,8 мега в минуту рекоменджуют лог на час файла два т.е. 80 мегов на файл округляем выходит 128 мег надо выставить

                          tmp_table_size = 1024M убавил до 128M
                          query_cache_size = 256M вчера еще сделал 32M может еще меньше сделать?
                          max_heap_table_size = 256M убавил на 64M
                          key_buffer = 16M Как его рассчитать не знаю, гдет читал чтобы было достаточно для помещения в буфер часто используемых индексов. МОжет не прав, поправьте

                            max_heap_table_size = 256M убавил на 64M
                            key_buffer = 16M Как его рассчитать не знаю, гдет читал чтобы было достаточно для помещения в буфер часто используемых индексов. МОжет не прав, поправьте
                            key_buffer_size используется только для MyISAM таблиц. его вообще 1М можно сделать и забить
                            Выдержка из мануала:
                            Index blocks for MyISAM tables are buffered and are shared by all threads
