They follow the same format and use the same query parameters. Those DA can be useful if you need to restart instances or other tasks within ant or other build/deployment systems.

Those routes + the direct actions explained in this document allow you to control almost everything remotely (make sure that your JavaMonitor installation is secure). As the direct actions, append //?pw=XXXX// to the URLs if JavaMonitor is password protected.
