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。

• Sending metrics to Graphite
• Sending metrics to InfluxDB
• Sending metrics to AWS CloudWatch
• Sending metrics to Datadog
• Sending metrics to StatsD
• Exposing metrics to Prometheus
• Exposing data as JMX MBeans

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
