QRwho

QRwho is a small tool to display the output of rwho and ruptime graphically. You get an overview of your Linux-Cluster and the load of each node at a glance.

Features

  • search for a hostname or parts of it
  • search for hosts on which a specific user is logged in
  • customizable command buttons which run a command on the target host and display the output (ssh-based)
  • colored alert, if a host is down or his maxload is overstepped
  • colored load display (interpolation of an rgb-spectrum)
  • define a default MaxLoad (colored alert, when the load is higher)
  • maxload per host

#MaxLoad per PC, format: MLhostname=Load
MLpool01=4.2
