Arthas Properties

The arthas.properties file is in the arthas directory.

  • If it is automatically downloaded arthas, the directory is under ~/.arthas/lib/3.x.x/arthas/

  • If it is a downloaded complete package, under the decompression directory of arthas

Supported configuration items

Note that the configuration must be camel case, which is different from the - style of spring boot. Only the spring boot application supports both camel case and - style configuration.

#arthas.config.overrideAll=true
arthas.telnetPort=3658
arthas.httpPort=8563
arthas.ip=127.0.0.1

# seconds
arthas.sessionTimeout=1800

#arthas.appName=demoapp
#arthas.tunnelServer=ws://127.0.0.1:7777/ws
#arthas.agentId=mmmmmmyiddddd

  • If the configuration of arthas.telnetPort is -1, the telnet port will not be listened. arthas.httpPort is similar.

  • If you configure arthas.telnetPort to 0, then random listen telnet port, you can find the random port log in ~/logs/arthas/arthas.log. arthas.httpPort is similar.

If you want to prevent multiple arthas port conflicts on a machine. It can be configured as a random port, or configured as -1, and use arthas through the tunnel server.

Configured order

The order of configuration is: command line parameters > System Env > System Properties > arthas.properties.

such as:

  • ./as.sh --telnet-port 9999 command line configuration will overwrite the default value arthas.telnetPort=3658 in arthas.properties.

  • If the application itself sets system properties arthas.telnetPort=8888, it will override the default value arthas.telnetPort=3658 in arthas.properties.

If you want arthas.properties to have the highest order, you can configure arthas.config.overrideAll=true.
