    配置说明：

    group 分类：代表心跳指标的某个类别的指标集合，例如 JVM、System、Disk等。

    • id : 分类名称
    • order : 心跳报表中的展示顺序

    metric 指标: 代表 group 中具体指标

    • id : 指标名称
    • unit : 指标数值的单位（K、M、G、自定义数值），图表显示值 = 真实值 / unit
    • delta : 是否增量统计，对业务方透明。
    • order : group 内的展示顺序
    • lable : 图表纵坐标的单位

    CAT 默认收集了部分心跳信息，例如 GC、JVM、System、Disk、FrameworkThread、CatUsage等。若有其他指标需求，可以做相应扩展代码以及心跳配置。
