MySQLD Exporter 插件基于标准的 MySQLD Exporter 实现。Rainbond 自带的 Prometheus 监控系统 rbd-monitor 会收集 Exporter 中的数据,并通过监控面板展示出来。用户可以自定义展示哪些关键性能数据的指标,这是监控 Mysql 数据库服务的不二之选。

安装 Mysql-Exporter 插件

在团队视图点击左侧的 「插件」 选项卡,进入我的插件页面。选择从应用商店安装/新建插件。

在开源应用商店中搜索 Mysql-exportor ,点击安装即可将插件安装到当前团队中。

在已有的 Mysql 服务组件的插件页面可以 「开通」 MySQLD Exporter 插件。

开通该插件后,「查看配置」 ,确认 DATA_SOURCE_NAME (MySQL 连接信息)是否正确。同时,也要确认时区的设置和被监控的 Mysql 服务组件是否一致。图中的配置代表使用 Asia/Shanghai 时区,Mysql 服务组件可以使用同样的环境变量配置来声明时区。

确认无误后,根据提示 「更新」 Mysql 服务组件,即可开始收集 MySQLD Exporter 提供的指标。


通过点击业务监控面板右上方的 「管理监控点」 ,可以定义监控点信息,这些信息定义了监控指标的来源。

MySQLD Exporter 插件已经定义好了一组监控点的配置,这组配置包含以下几个元素,这些元素都是必填项:

  • 配置名称:自定义这组配置的名字
  • 收集任务名称:自定义
  • 路径:指标的来源路径,根据 Exporter 设计的不同,需要填写合适的路径
  • 端口:Exporter 监听的端口,默认监听 9104,用户需要为 Mysql 主服务开启 9104 端口的对内服务。
  • 收集时间间隔: 多久收集一次指标


这一插件已经默认配置好了常用的监控图表,点击一键导入,使用 mysqld-exportor 方案即可生成图表。

依次点击 「监控」 —— 「业务监控」 便可以看到相应的监控图表:

默认的监控图表展示的 MySQLD 业务监控数据项包括:

Table Lock lmmediate
Table Lock Waited



点击业务监控面板上方的 「添加图表」

输入新的标题,以及对应的查询条件 mysql_global_status_threads_connected 后,点击 「查询」。如果正常返回图表,则说明查询条件是正确的。标题的定义尽量清晰明了,并在有必要的情况下明确单位。

点击 「添加」 后,即可将新的监控图表加入业务监控面板。新添加的监控图表将会置于最后。

访问 Mysql 服务组件的 9104 端口,可以在 /metrics 路径下,查看所有可供成图的监控项。

    Tracking cellphones and getting an accurate report has been a bit worrisome, thanks to Jeffrey whose service helped me locate certain cellphones without breaking a sweat. His service made me know that the internet has become the most common method of cheating nowadays, either emotionally or physically. Taking a few extra steps in getting what would serve as proof for leaving a toxic relationship, to see who your spouse texts or chats with on social media isn’t a bad idea, I’d recommend you reach out to Jeffreyethicalhacker@gmail.com
