Запросы в ClickHouse CloudДанные в этой системной таблице хранятся локально на каждом узле ClickHouse Cloud. Поэтому, чтобы получить полное представление обо всех данных, требуется функция
clusterAllReplicas. Дополнительные сведения см. здесь.Описание
SELECT было обработано с момента запуска сервера ClickHouse.
Столбцы
event(String) — Имя события.value(UInt64) — Количество произошедших событий.description(String) — Описание события.
Пример
См. также
- system.asynchronous_metrics — Содержит метрики, вычисляемые периодически.
- system.metrics — Содержит метрики, вычисляемые мгновенно.
- system.metric_log — Содержит историю значений метрик из таблиц
system.metricsиsystem.events. - Мониторинг — Основные понятия мониторинга ClickHouse.

DNSError
Данные после слияния отличаются от данных на реплике
- Использование более новой версии библиотеки сжатия после обновления сервера.
- Использование другого метода сжатия.
- Недетерминированный алгоритм сжатия (крайне маловероятно).
- Недетерминированный алгоритм слияния из-за логической ошибки в коде.
- Повреждение данных в памяти из-за ошибки в коде.
- Повреждение данных в памяти из-за аппаратной проблемы.
- Ручное изменение исходных данных после запуска сервера.
- Ручное изменение контрольных сумм, хранящихся в ZooKeeper.
- Настройки, связанные с форматом частей, такие как ‘enable_mixed_granularity_parts’, различаются на разных репликах. Сервер обнаружил эту ситуацию и загрузит слитую часть с реплики, чтобы обеспечить побайтно идентичный результат.
