JarCastingjvm运行状态监控
项目介绍
本项目通过MXBean获取jvm运行的状态信息，并通过Netty提供http服务提取数据。 默认端口20000,
- 可以通过monitor.port系统参数配置，如:
-Dmonitor.port=10001
- 可以通过monitor.skip=true配置不启动
- 可以通过monitor.path=/monitor 配置请求路径
监控项目如下：
- os:操作系统信息
- sys：运行系统信息
- gc：jvm发生GC的时间和次数
- thread：线程信息（当前活动数，历史活动数等）
- threads：线程详情
- memory：内存基本信息
- memoryAll：单行列出内存的信息
- compilation：编译信息
- runtime：运行参数信息（启动参数等）
使用方法
maven添加依赖
<dependency>
<groupId>io.github.jnan88</groupId>
<artifactId>monitor-jvm</artifactId>
<version>0.0.1</version>
</dependency>
在spring中使用配置：
<bean class="io.github.jnan88.monitor.jvm.MonitorServer" init-method="start" destroy-method="stop" lazy-init="true"></bean>
获取数据
请求方式：
GET http://you_ip:you_port/monitor?t=x&v
请求参数:
|参数名|作用|描述| |--|--| |type|获取结果的内容|os,sys,gc,thread,threads,memory,compilation,runtime多个使用英文逗号间隔,all表示获取全部| |pretty|是否对结果进行格式化，默认不格式化|任意值| |format|是否对结果进行分组，分组则gc的参数在gc节点下，默认不分组|任意值|
响应参数： memoryAll:为init,used,committed,max

更新记录
- 20180111：新增通过系统配置monitor.skip=true不开启，避免修改配置文件
- 20180112：新增请求参数format控制是否对结果进行分组，新增通过monitor.path=/monitor 配置请求路径，代码优化通过反射调用获取结果信息
- 20180125：测试发现如果lazy-init=true时，会造成spring的启动被lock住，无法正常启动，所以需要在Spring启动中通过ApplicationContext获取一次对象进行初始化进行启动
- 20180208：增加java web项目启动使用servlet对外提供数据
