I'm used to always seeing the CPU utilization monitor. It's easy to see who's doing illegal activities 😎 Not finding a standard Qubes solution, I wrote a little script for xfce panel item "Generic Monitor". Maybe someone will find it useful or say that I invented a crooked bicycle and there is a much better one.

It looks like this in a dark theme:

The script to be copied to the Dom0:

#!/usr/bin/perl

# indicator length
my $il = 25;

my $name_max = '';
my $cpu_max = -1;

open(my $top, '-|', 'xentop -bi2 -d1') || die $!;

while (<$top>) {
        next if /^\s*NAME/ ... /^\s*NAME/;
        s/^\s+//;
        my @s = split /\s+/;
        my $cpu = eval{$s[3]/$s[8]} || 0;
        if ($cpu > $cpu_max) {
                $name_max = $s[0];
                $cpu_max = $cpu;
        }
}

my $v = 1 + int($cpu_max * $il / 100); 

print '|' x $v, '.' x ($il-$v), "\n", $name_max, ' ', int $cpu_max;
