Summary插件

对系统的信息进行采样，支持级联采样，即从服务器会向主服务器报告数据

如果没有订阅者则不进行采集，节省系统资源

默认配置

[Summary]
SampleRate = 1

• SampleRate 采样率，单位秒，即每一秒采样一次

数据结构

type ServerSummary struct {
	Address string
	Memory  struct {
		Total uint64
		Free  uint64
		Used  uint64
		Usage float64
	}
	CPUUsage float64
	HardDisk struct {
		Total uint64
		Free  uint64
		Used  uint64
		Usage float64
	}
	NetWork     []NetWorkInfo
	Streams     []*Stream
	lastNetWork []NetWorkInfo
	ref         int
	control     chan bool
	reportChan  chan *ServerSummary
	Children    map[string]*ServerSummary
}

API

• /api/summary 获取采样数据，这个接口返回一个SSE

上报逻辑

graph LR
    从服务器 --上报--> 主服务器
    主服务器 --推送--> 用户页面
