#### 概述

此章节提供了[仪表盘](/manual/web_interface/frontend_sections/monitoring/dashboard)组件的通用参数细节。

#### 通用参数

以下参数对每个组件都是通用的：

|   |   |
|---|---|
|*名称*|输入组件名称。|
|*刷新间隔*|配置默认刷新间隔。组件的默认刷新间隔从*不刷新*到*15分钟*取决于组件的类型。示例：URL组件是*不刷新*，动作记录组件是*1分钟*，时钟组件是*15分钟*。|
|*显示组件头部*|勾选多选框来永久显示组件头部。<br>当取消勾选时，无论在查看还是编辑模式，为了节省空间，头部会被隐藏，只有在鼠标位于组件上方时向上滑动能重新显示头部。当拖动组件到新位置时，头部也会部分可见。|

组件的刷新间隔可为所有相关用户设为一个默认值，也可为每个用户单独设置其刷新间隔：

-   要为所有相关用户设为一个默认值，切换到编辑模式（点击*编辑仪表盘*按钮，
    找到正确的组件，点击*编辑*按钮打开组件的编辑表单），之后在下拉菜单中
	选择需要的刷新间隔。
-   要为每个用户单独设置其刷新间隔，在查看模式中，点击一个组件的
    ![](../../../../../../assets/en/manual/web_interface/frontend_sections/monitoring/dashboard/edit_button_widget_view.png)
	按钮。

一个用户设置的单独的刷新间隔优先级高于组件设置，并且一旦设置了单独
的刷新间隔，即使组件设置被修改，它也会一直保持不变。
