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

Version 1.0

• Tar-Ball:
• Debian-Package:

• Tar-Ball: qrwho.tar.gz
• Debian-Package:

<xterm> > cd qrwho > make $> ./qrwho </xterm>

• qt-libs
• 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:

<xterm> #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

</xterm>
