带有 Tomcat 8.0.5 的 JavaMelody 1.52.0 - 未找到监控答案

【问题标题】：JavaMelody 1.52.0 with Tomcat 8.0.5 - Monitoring Not FOund带有 Tomcat 8.0.5 的 JavaMelody 1.52.0 - 未找到监控
【发布时间】：2014-10-23 11:52:00
【问题描述】：

这是我的设置：

Apache Tomcat：8.0.5

JavaMelody：1.52.0 - 通过 Maven 依赖添加

<dependency>
  <groupId>net.bull.javamelody</groupId>
  <artifactId>javamelody-core</artifactId>
  <version>1.52.0</version>
</dependency>

web.xml

<?xml version="1.0" encoding="UTF-8"?>

应用通过tomcat-maven-plugin部署：

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <configuration>
       <url>http://domain.com:8080/manager/text</url>
       <server>tomcat</server>
       <path>/something</path>
    </configuration>
</plugin>

根据 catalina.out，JavaMelody init 似乎没问题：

如何访问监控页面？两者都不： http://domain.com:8080/something/monitoring 也不： http://domain.com:8080/something/services/monitoring 正在工作。

【问题讨论】：

看起来很健康。嗯。尝试添加此处看到的日志选项：code.google.com/p/javamelody/wiki/…。
我开启了日志记录。不幸的是，catalina.out 中没有比上面显示的更多的日志记录行。我想这是因为 JavaMelody 在请求某些内容之前无事可做，但这需要知道路径。
该链接还显示了路径。它的server:port/<app context>/monitoring。所以在你的情况下，我认为它应该是domain.com:8080/something/monitoring，因为这个日志行“2014-08-29 14:33:28,677 [localhost-startStop-1] DEBUG net.bull.javamelody - Webapp context: /something”。
“某物”应用程序是否可以访问，即使旋律不可用？
是的，domain.com:8080/something/monitoring 是我一开始一直在尝试的。

标签： java tomcat web.xml java-melody

【解决方案1】：

我通过从 web.xml 中删除以下行来使其工作（见上文）：

<servlet-mapping>
   <servlet-name>default</servlet-name>
   <url-pattern>/static/*</url-pattern>
</servlet-mapping>

我将此作为“错误”报告给 JavaMelody 的作者。不确定它是否真的是一个。
