    longDescription = ''
      Atop is an ASCII full-screen performance monitor that is capable of reporting the activity of
      all processes (even if processes have finished during the interval), daily logging of system
      and process activity for long-term analysis, highlighting overloaded system resources by using
      colors, etc. At regular intervals, it shows system-level activity related to the CPU, memory,
      swap, disks and network layers, and for every active process it shows the CPU utilization,
      memory growth, disk utilization, priority, username, state, and exit code.
