-`read_rows` ([UInt64](../../sql-reference/data-types/int-uint.md#uint-ranges)) — Total number or rows read from all tables and table functions participated in query. It includes usual subqueries, subqueries for `IN` 和 `JOIN`. 对于分布式查询 `read_rows` 包括在所有副本上读取的行总数。 每个副本发送它的 `read_rows` 值,并且查询的服务器-发起方汇总所有接收到的和本地的值。 缓存卷不会影响此值。
-`read_bytes` ([UInt64](../../sql-reference/data-types/int-uint.md#uint-ranges)) — Total number or bytes read from all tables and table functions participated in query. It includes usual subqueries, subqueries for `IN` 和 `JOIN`. 对于分布式查询 `read_bytes` 包括在所有副本上读取的行总数。 每个副本发送它的 `read_bytes` 值,并且查询的服务器-发起方汇总所有接收到的和本地的值。 缓存卷不会影响此值。
-`client_hostname` ([字符串](../../sql-reference/data-types/string.md)) — Hostname of the client machine where the [ツ环板clientョツ嘉ッツ偲](../../interfaces/cli.md) 或者运行另一个TCP客户端。
-`client_version_major` ([UInt32](../../sql-reference/data-types/int-uint.md)) — Major version of the [ツ环板clientョツ嘉ッツ偲](../../interfaces/cli.md) 或另一个TCP客户端。
-`client_version_minor` ([UInt32](../../sql-reference/data-types/int-uint.md)) — Minor version of the [ツ环板clientョツ嘉ッツ偲](../../interfaces/cli.md) 或另一个TCP客户端。
-`client_version_patch` ([UInt32](../../sql-reference/data-types/int-uint.md)) — Patch component of the [ツ环板clientョツ嘉ッツ偲](../../interfaces/cli.md) 或另一个TCP客户端版本。
-`ProfileEvents.Names` ([数组(字符串)](../../sql-reference/data-types/array.md)) — Counters that measure different metrics. The description of them could be found in the table [系统。活动](../../operations/system-tables/events.md#system_tables-events)
-`Settings.Names` ([数组(字符串)](../../sql-reference/data-types/array.md)) — Names of settings that were changed when the client ran the query. To enable logging changes to settings, set the `log_query_settings` 参数为1。
-[system.query_thread_log](../../operations/system-tables/query_thread_log.md#system_tables-query_thread_log) — This table contains information about each query execution thread.
