embedded-jmxtrans 整合 Spring、Servlet、InfluxDB

1、Servlet Integration

参考EmbeddedJmxTransLoaderListener对象注解

<context-param>
    <param-name>jmxtrans.config</param-name>
    <param-value>
        classpath:jmxtrans.json
        classpath:org/jmxtrans/embedded/config/jmxtrans-internals-servlet-container.json
        classpath:org/jmxtrans/embedded/config/tomcat-7.json
        classpath:org/jmxtrans/embedded/config/jvm-sun-hotspot.json
    </param-value>
</context-param>
<listener>
    <listener-class>org.jmxtrans.embedded.servlet.EmbeddedJmxTransLoaderListener</listener-class>
</listener>

2、Spring Integration

本人参考 embedded-jmxtrans 的github地址 https://github.com/jmxtrans/embedded-jmxtrans/wiki 配置后，测试完全无效。
阅读代码后采用另种方式：

配置EmbeddedJmxTransFactory

<bean id="jmxtrans" class="org.jmxtrans.embedded.spring.EmbeddedJmxTransFactory" destroy-method="destroy" scope="singleton">
    <!-- JMX对象名称  -->
    <property name="beanName" value="jmxtrans"/>
    <!-- 监听配置文件变化: 每60秒检测一次  -->
    <property name="configurationScanPeriodInSeconds" value="60"/>
    <!-- 如果未发现指定的配置文件 ，是否忽略 -->
    <property name="ignoreConfigurationNotFound" value="true"/>
    <!-- 初始配置文件 -->
    <property name="configurationUrls">
        <list>
             <value>classpath:jmxtrans.json</value>  
             <value>classpath:org/jmxtrans/embedded/config/tomcat-7.json</value>
             <value>classpath:org/jmxtrans/embedded/config/jmxtrans-internals.json</value> 
             <value>classpath:org/jmxtrans/embedded/config/jvm-sun-hotspot.json</value>
         </list>
    </property>
</bean>

使用EmbeddedJmxTransFactory；此处发现如果不引用上面的对象，则无法调用getObject方法实现对象初始化

<bean class="org.jmxtrans.embedded.EmbeddedJmxTransLauncher">
    <property name="jmxtrans" ref="jmxtrans"/>
</bean>

3、InfluxDB Integration

在第二则中提到配置文件 jmxtrans.json；为了将数据自己输出到InfluxDB,我拷贝了jmxtrans-output-influxdb的代码，做了一些调整，配置如下：

{
    "queries": [
        {
            "objectName": "Catalina:type=Manager,context=/,host=*",
            "resultAlias": "application.activeSessions",
            "attributes": [
                "activeSessions"
            ]

        }
    ],
    "outputWriters": [
        {
            "@class": "org.jmxtrans.embedded.output.Slf4jWriter",
            "settings": {
                "enabled": "${jmxtrans.writer.slf4j.enabled:true}"
            }
        },
        {
            "@class": "org.jmxtrans.embedded.output.influxdb.InfluxDbOutputWriter",
            "settings": {
                "enabled": "${jmxtrans.writer.influxdb.enabled:true}",
                "url": "${jmxtrans.writer.influxdb.url:http://localhost:8086}",
                "database": "${jmxtrans.writer.influxdb.database:APP_Metrics}",
                "user": "${jmxtrans.writer.influxdb.user:admin}",
                "password": "${jmxtrans.writer.influxdb.password:admin}",
                "tags": "${jmxtrans.writer.influxdb.tags:host=#hostname#}"

            }
        }
    ]
}
