Start as a Java Agent

Usually Arthas dynamic attach the applications on the fly, but from version 3.2.0 onwards, Arthas supports starting directly as a java agent.

For example, download the full arthas zip package, decompress it and start it by specifying arthas-agent.jar with the parameter -javaagent.

java -javaagent:/tmp/test/arthas-agent.jar -jar math-game.jar

The default configuration is in the arthas.properties file in the decompression directory. Reference: Arthas Properties
