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。
