|
||||
- `entry` ([String](../../sql-reference/data-types/string.md)) — идентификатор запроса.
|
||||
- `host_name` ([String](../../sql-reference/data-types/string.md)) — имя хоста.

- `host_address` ([String](../../sql-reference/data-types/string.md)) — IP-адрес хоста.
|
||||
- `port` ([UInt16](../../sql-reference/data-types/int-uint.md)) — порт для соединения с сервером.
|
||||
- `status` ([Enum8](../../sql-reference/data-types/enum.md)) — состояние запроса.
|
||||
- `cluster` ([String](../../sql-reference/data-types/string.md)) — имя кластера.
|
||||
- `query` ([String](../../sql-reference/data-types/string.md)) — выполненный запрос.
|
||||
- `initiator` ([String](../../sql-reference/data-types/string.md)) — узел, выполнивший запрос.
|
||||
- `query_start_time` ([DateTime](../../sql-reference/data-types/datetime.md)) — время начала запроса.
