Referring to Google's 4 golden indicators, for the registration center, I
think the following indicators are needed.
- dubbo_registry_duration_seconds
Interaction delay, interaction behavior includes service register,
subscription, heartbeat, indicating the network connection status of the
application and registry center
- dubbo_registry_notify_total
The change notification push received by the consumer side indicating the
frequency of the service provider online or offline
- dubbo_registry_connect_total
The number of times to reconnect with the registry center, indicating the
available time of the registry center
In addition, a large change in the number of application instances will lead
to an increase in received push traffic, which may cause a huge change in
【memory usage】 and have a greater impact on the 【gc】 of the current application.
These two indicators belong to the system indicators and are not included
for the time being.
中文：参考google四大黄金指标，我认为注册中心应该需要的指标如下：
- dubbo_registry_duration_seconds
交互延迟，交互行为包含注册、订阅、心跳，反映应用和注册中心的网络连接状况
- dubbo_registry_notify_total
consumer端接收到的变更通知推送，反映服务提供者上下线的频率
- dubbo_registry_connect_total
与注册中心重连的次数，反映注册中心的可用时间
另外，应用实例数的大量变化会导致接收的推送流量增大，可能会造成内存使用的巨大变化，并且对当前应用的gc造成较大影响。
这两个指标属于系统指标，暂时不列入。
Anyone have suggestions?
