 # jmx_minxie
 A simple JMX agent for monitoring Java applications.
 
-e.g. for monitoring the number of threads in a Java application.
+## 怎么使用?
+jmx_agent 提供了assembly打包插件，可通过assembly:assembly 打出一个带依赖的包
+jmx_agent-1.0-SNAPSHOT-jar-with-dependencies.jar
 
+这个包是一个agent的包，可以通过-javaagent启动
+例如
+> java -jar -javaagent:jmx_agent-1.0-SNAPSHOT-jar-with-dependencies.jar=12345 demo.jar
+
