javamelody是一款监测java应用，支持获取如cpu，内存，线程数，http访问，sql等数据。

支持metrics，提供接口供其他第三方抓取。

1.官方提供了springboot2.0的集成方案。

pom文件增加如下依赖

        
     
      net.bull.javamelody
         
     
      javamelody-spring-boot-starter
         
     
      1.74.0
     
    

2.通过其他方式集成

pom文件增加如下依赖

    
    	
     
      net.bull.javamelody
     	
     
      javamelody-core
     	
     
      1.74.0
     
    

新增如下类

https://github.com/javamelody/javamelody/blob/without-spring-boot-starter/javamelody-for-spring-boot/src/main/java/hello/JavaMelodyConfiguration.java

之后访问地址：http://127.0.0.1:8080/monitoring即可

如需个性化配置

# Enable JavaMelody auto-configuration (optional, default: true)javamelody.enabled=true# Data source names to exclude from monitoring (optional, comma-separated)javamelody.excluded-datasources=secretSource,topSecretSource# Enable monitoring of Spring services and controllers (optional, default: true)javamelody.spring-monitoring-enabled=true# Initialization parameters for JavaMelody (optional)# See: https://github.com/javamelody/javamelody/wiki/UserGuide#6-optional-parameters#    log http requests:javamelody.init-parameters.log=true#    to exclude images, css, fonts and js urls from the monitoring:# javamelody.init-parameters.url-exclude-pattern=(/webjars/.*|/css/.*|/images/.*|/fonts/.*|/js/.*)#    to aggregate digits in http requests:# javamelody.init-parameters.http-transform-pattern: \d+#    to add basic auth:# javamelody.init-parameters.authorized-users=admin:pwd#    to change the default storage directory:# javamelody.init-parameters.storage-directory=/tmp/javamelody#    to change the default "/monitoring" path:# javamelody.init-parameters.monitoring-path=/admin/performance

如图所示，可以查看cpu，内存等

http请求等

支持主动执行垃圾回收以及dump文件
