配置示例说明

心跳模板配置的Sample如下：

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。
