I think we need do this in DP, not admin API

And we should implement this feature by plugin way.
Take a look at: https://github.com/apache/apisix/blob/master/apisix/plugins/node-status.lua

5 seconds is short, I think 10 mins should be good

I still think 10 mins is too long, also for now, all the basic server info are static (except the up_time and last_report_time), a relative short period is more suitable so we can easily judge whether a node is healthy or unstable when we are viewing the server info on Dashboard.
What about 1 min or 2 mins?

@agile6v We can add some limit to the report interval, such as the minimal report interval is 10s. |
