使用javamelody进行web监控

1、引入maven依赖

<dependency>
        <groupId>net.bull.javamelody</groupId>
        <artifactId>javamelody-core</artifactId>
        <version>1.70.0</version>
</dependency>`

2、配置web.xml

初始化启动参数增加monitoring-spring.xml

<filter>
        <filter-name>javamelody</filter-name>
        <filter-class>net.bull.javamelody.MonitoringFilter</filter-class>
        <async-supported>true</async-supported>
    </filter>
    <filter-mapping>
        <filter-name>javamelody</filter-name>
        <url-pattern>/monitoring</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>ASYNC</dispatcher>
    </filter-mapping>
    <filter-mapping>
        <filter-name>javamelody</filter-name>
        <url-pattern>/rest/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>ASYNC</dispatcher>
    </filter-mapping>
    <listener>
        <listener-class>net.bull.javamelody.SessionListener</listener-class>
    </listener>

3、监控的地址

http://ip:port/serverName/monitoring

4、更多的参考

5、问题总结

c3p0数据源怎么监控

 <bean id="mainDataSource" class="net.bull.javamelody.SpringDataSourceFactoryBean">
        <property name="targetName" value="dataSource" />
    </bean>

6、springboot集成javamelody

引入依赖

 <dependency>
            <groupId>net.bull.javamelody</groupId>
            <artifactId>javamelody-core</artifactId>
            <version>1.72.0</version>
        </dependency>

```
@Configuration
public class JavamelodyConfiguration {

@Bean
public FilterRegistrationBean monitorFilter() {
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(new MonitoringFilter());
    filterRegistrationBean.addUrlPatterns("/*");
    return filterRegistrationBean;
}

@Bean
public ServletListenerRegistrationBean sessionListener() {
    ServletListenerRegistrationBean servletListenerRegistrationBean = new ServletListenerRegistrationBean();
    servletListenerRegistrationBean.setListener(new SessionListener());
    return servletListenerRegistrationBean;
}

}
