Question

首先让我说我不是Tomee / TomCat专家。

我有一个应用程序（.war）在AWS的ECS / Fargate上基于Tomee的Docker容器中运行。我试图让Tomee将所有日志发送到STDOUT，以便将来自应用程序的日志发送到AWS中的CloudWatch。我已经尝试过建议/答案in this question，但是即使在本地测试，我仍然看不到应用程序日志：

docker logs -f myapp

这是带有添加的 java.util.logging.ConsoleHandler的logging.properties文件：

handlers = 1catalina.org.apache.juli.AsyncFileHandler, 2localhost.org.apache.juli.AsyncFileHandler, 3manager.org.apache.juli.AsyncFileHandler, 4host-manager.org.apache.juli.AsyncFileHandler, org.apache.tomee.jul.formatter.AsyncConsoleHandler
.handlers = 1catalina.org.apache.juli.AsyncFileHandler, org.apache.tomee.jul.formatter.AsyncConsoleHandler, java.util.logging.ConsoleHandler

我已经按照/usr/local/tomee/bin/中的建议添加了一个环境变量：

#!/bin/bash
CATALINA_OUT=/dev/stdout

所有发送到STDOUT的日志都会自动发送到AWS Cloudwatch（我可以在那看到Catalina日志中的信息），但访问/错误日志却没有。

我在这里错过了什么吗？还是有一种更简单的方法来确保在CloudWatch中可以看到应用程序的日志？

经过大量研究，我发现在server.xml中使用以下语句将使用AccessLogValve将日志发送到STDOUT：

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="/dev/stdout"
   prefix="" suffix="" rotatable="false"
   pattern="%h %l %u %t &quot;%r&quot; %s %b" />

OR

<Valve className="[...].AccessLogValve" directory="/dev"
    prefix="stdout" suffix="" fileDateFormat=""
    pattern="%h %l %u %t &quot;%r&quot; %s %b"
/>

根据Tomcat / Tomee的版本，这两种方法都可以很好地工作，而无需将实际日志软链接到/dev/stdout

Docker，Tomee，日志记录，STDOUT，AWS
