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.

• 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

• Debian-Package:

$> tar xvzf qrwho.tar.gz
$> cd qrwho
$> qmake
$> make
$> ./qrwho

• rwho & ruptime
• ssh

QRwho searches for it's configuration-file ("config") the current working directory. If it is not found, QRwho uses this standard config:

#Default maximal Load:
MaxLoad=2
#Show command-buttons, values: 0/1
CMDS=1
#Define commands for each button
NodeCMD1=cat /proc/meminfo
NodeCMD2=dmesg
NodeCMD3=ps auxf
NodeCMD4=lsb_release -c
NodeCMD5=uname -a

#Load minimal and maximal color (RGB)
MinColor=0,200,255
MaxColor=150,200,0

#MaxLoad per PC, format: MLhostname=Load
MLpool01=4.2
MLpool02=2
