kaa-node.log

我正在尝试Kaa服务器，我在kaa-node.log文件中找到了一些消息。 我不确定这些消息是否会影响Kaa服务器的正常工作。

  1. “无法在日志文件中查找端点的GLOBAL actor”。

    2. 例如： 2016-10-30 23：56：10,582 [EPS-core-dispatcher-11] WARN okksosaacApplicationActor - [[90,73，-91，-2,123,48,26，-63,92,70,22， 116，-14,54，-122,115,83，-83,61，-86]]无法为端点查找GLOBAL actor。

    虽然日志文件中有消息，但似乎Kaa服务器仍能正常工作。

    1. org.kaaproject.kaa.server.common.dao.exception.DatabaseProcessingException：端点配置文件未订阅此主题 （附上如下代码示例块的消息）

      2. 在向某些端点发送单播通知时，似乎会出现此消息，但这些端点不会订阅此主题。 我还发现在这些消息发生后，CPU负载将从8％增加到大约55％。 虽然Kaa服务器似乎正常工作，但CPU负载似乎保持在50-60％。

      有谁知道上述消息的含义？ 并且在第二条消息出现后，无论如何都要降低CPU负载。

1 个答案:

答案 0 :(得分：0)

正如我在上面的评论中所写：

第一条消息并不表示系统工作不正常只是未能查找GLOBAL actor，它会再次尝试查找。最后，EP将连接到Kaa服务器。

第二条消息是预期的 - Kaa​​服务器引发异常，因为您向EP发送了单播通知，该EP未订阅此主题，因此阻止了不可接受的操作。此外，我确实观察到此异常后CPU负载的任何增加。
