In this window, you can filter the session to be listed by adding some filter conditions. 

  • Check "Frontend Only" (Default), it will show all USER sessions only, otherwise, it will show all sessions including system sessions
  • Tick "Filter", you can add more advanced filters as you wish. For example, you can filter the sessions owned by user "DEMO" only, or you can show the sessions running SQL containing the text "MASTER_TABLE".

After you choose a session, you can do 3 operations on it
