cadvisor：工厂“docker”无法处理容器“/system.slice/kdump.service”

Question

当我盯着 cAdvisor 时，我收到了Factory "docker" was unable to handle container "/system.slice/kdump.service"。我试图了解这些是什么，以及......如何解决？

任何指针将不胜感激。

kdump.service 是系统服务，而不是 Docker 容器。你可以阅读更多关于它的信息here。您在日志中看到的是调试信息，告诉您 cAdvisor 没有内核转储服务的处理程序。这不是一个错误，它只是因为您增加了详细程度而可见（command: 中的"-v=4"）。您可以减少冗长或直接忽略这些消息。
