目前好像没办法调整,不过3.0有计划重新设计一下健康检查相关的部分。

大佬,另外发现使用HTTP对持久节点健康检查时,naming-server.log中打印大量的Client change for service .......http check started before last one finished日志,节点大量不健康,请问可能的原因是什么呢?

Client change for service ....... 这个日志就是某个服务的某个实例发生了变化, 比如健康检查状态变了,或者有新注册,或者更新。
http check started before last one finished 这个日志应该就是你上面提的问题,因为连接超时,或者线程池不足,导致任务积压了,下一次的检查任务已经启动,但是之前的还没有结束。

如果目前已经出现这个问题,建议扩容nacos节点,把健康检查的压力分散到多个节点上。

Client change for service发生的频率非常高,毫秒级地在刷新日志;
探活频率的问题我通过改代码的方式暂时解决了
