Как получить логи Базы данных

Примечание

Логи баз данных используются только на БД, которые были созданы после 1 декабря 2020 года.

Для получения логов необходимо подключиться к БД по SSH, сейчас их можно получить для следующих БД:

  • MySQL
  • PostgreSQL/PostgresPro
  • ClickHouse
  • Redis
  • MongoBD

Ниже можно узнать подробнее, как получить логи для каждого типа БД.

 

MySQL

Чтобы получить логи, нужно подключиться по SSH и ввести команду:

[admin@mysql-8658 ~]journalctl -u mysqld

После этого будет получен ответ:
