统计

etcd集群对延时,带宽,和运行时间都有统计,通过统计信息,可以了解集群内部的健康状态

leader统计信息

主节点拥有整个集群的视野,主要关心两类信息

  • 到每个节点的延时
  • 成功和失败的Raft RPC请求

[root@docker ~]# curl http://127.0.0.1:2379/v2/stats/leader
{"leader":"ce2a822cea30bfca","followers":{}}[root@docker ~]# 
[root@docker ~]#  

我的环境中还没有followers,所以是空的

下面是官方文档中的示例

curl http://127.0.0.1:2379/v2/stats/leader
