Tech Short: Ubuntu Server System Information on login

If you have run Ubuntu Server you may have noticed that each time you log into your system via SSH system information  status are displayed.

I have wondered this for a while now and tonight I found out.

The command to reproduce this information is
landscape-sysinfo

This command is run from /etc/update-motd.d/50-landscape-sysinfo and exists when the landscape common package is installed on the server from what I have read.

And now I know.

A look inside the script:

#!/bin/sh
cores=$(grep -c ^processor /proc/cpuinfo 2>/dev/null)
[ “$cores” -eq “0” ] && cores=1
threshold=”${cores:-1}.0″
if [ $(echo “`cut -f1 -d ‘ ‘ /proc/loadavg` < $threshold” | bc) -eq 1 ]; then
echo
echo -n ” System information as of “
/bin/date
echo
/usr/bin/landscape-sysinfo
else
echo
echo ” System information disabled due to load higher than $threshold”
fi
