@tokers I have another question. When a new request activates the health check, how long will the route revoke the health check if there is no new request? Is there any guidance document for this?

It won't. You can see https://kong.github.io/lua-resty-healthcheck/topics/readme.md.html for more details.

I don't understand this. Do you mean the expiry time of the health check data in the shared dict?

I mean, will it become lazy again after activation?
Is there any guidance document about this feature?

The active health check will send probes to the endpoints (for both the healthy set and the unhealthy set) periodically. So status will be updated in time.
