as.sh and arthas-boot tips

  • Select the process to be attached via the select option.

Normally, as.sh/arthas-boot.jar needs to a pid, bacause the pid will change.

For example, with math-game.jar already started, use the jps command to see.

$ jps
58883 math-game.jar
58884 Jps

The select option allows you to specify a process name, which is very convenient.

$ ./as.sh --select math-game
