35.1 安装 OpenTelemetry 支持

本节介绍服务器和客户端 OpenTelemetry 支持的安装。

安装服务器组件

要安装服务器组件，请运行以下命令

Press CTRL+C to copy
 
install component 'file://component_telemetry';

要确认组件是否存在于您的服务器中，请运行以下查询

Press CTRL+C to copy
 
mysql> select * from mysql.component;
+--------------+--------------------+------------------------------------+
| component_id | component_group_id | component_urn                      |
+--------------+--------------------+------------------------------------+
|            1 |                  1 | file://component_validate_password |
|            2 |                  2 | file://component_telemetry         |
+--------------+--------------------+------------------------------------+

如果 component_urn 列中存在 component_telemetry，则表示组件已安装。

组件安装还会添加特定于遥测的系统变量。

mysql> show variables like "%telemetry%";

请参阅服务器配置。

安装客户端插件

可以通过命令行开关 --telemetry_client 或在配置文件的 [mysql] 部分中定义的配置选项 telemetry-client=ON |OFF 启用 MySQL 客户端的遥测插件。
