最近在项目中使用spring-boot-admin监控应用，spring-boot版本为1.5.10.RELEASE，每次进行查看时，都会在目标应用处报错

根据这个报错，可以猜测和日志有关。一开始以为是spring-boot-admin对endpoint请求不规范等问题导致的错误，后来试了几个不同的版本，都无法解决。遂上stackoverflow搜索，也未发现有相关思路。

经过一番苦找，终于在bing搜索到的一个issues#8639发现了端倪。

里面如下提到：

I've replicated this locally. The root cause is we don't know how to map ALL to one of our LoggingLevelvalues.

Our current mappings are:

LEVELS.map(LogLevel.TRACE, Level.TRACE);
LEVELS.map(LogLevel.DEBUG, Level.DEBUG);
LEVELS.map(LogLevel.INFO, Level.INFO);
LEVELS.map(LogLevel.WARN, Level.WARN);
LEVELS.map(LogLevel.ERROR, Level.ERROR);
LEVELS.map(LogLevel.FATAL, Level.ERROR);
LEVELS.map(LogLevel.OFF, Level.OFF);

我的应用中使用的是log4j2，检查了一下log4j2.xml文件，发现有一处使用了ALL等级

<root level="ALL">

尝试将 ALL 改为 INFO，问题解决

看了下原来提出那个issues的人，用的是logback，看来这个应该不是对log4j2的适配问题

而是spring-boot-actuator对于ALL等级的支持目前还是有一定的问题，只能用比较具体的等级去设置
