   > What is the difference between an active health check and a passive health check that you implement? Is there a detailed documentation?
   
   here: https://github.com/apache/apisix/blob/master/docs/en/latest/health-check.md
   
   > Do both active and passive checks have to exist?
   
   no need, but your configuration will turn on the default passive health check.
   
   you can set `log_level` to `debug` to get more logs about the health changes of the nodes.
