Describe the bug 部署了kindling-agent服务后,过了约5个小时后,发现集群部分节点load突然增高,影响到集群的稳定性。 并且是三个节点同时出现该问题。如下是三个节点的负载情况:
并且在这个时间点,系统日志开始大量打印如下日志:
持续打印,简单统计下,发现每分钟日志量达8K+
How to reproduce? kindling-agent daemonset 和configmap文件如下:
deploy+kindlingcfg.zip
What did you expect to see? 正常情况不应该出现这个问题
What did you see instead?

这个问题在使用内核模块时可能会出现。系统触发了epoll事件,而内核模块处理该事件的流程较长,会持续打印内核日志,导致CPU load升高。该问题已经在 #590 中解决。
Sorry, something went wrong.
感谢,不过我看 #590 修复是是内核模块去掉了epoll事件的输出,那去掉对epoll事件的输出和没去掉之前有功能上的差异吗?比如某些需要的事件会没有了?
该事件主要在Trace Profiling功能中需要,网络指标中不受影响。
在Trace Profiling功能中,如果使用内核模块,在线程上会无法看到epoll事件的详细信息。
