…tion:
($user, $cpu, $memory, $command) = $l =~ m{^(\w+)\s+\d+\s+(\d{1,2}\.\d)\s+(\d{1,2}\.\d).*\d{1,2}:\d{2}\s+(.*)$};
Problems:
(\w+) only matches word characters, but user:20 in ps pads usernames with spaces.
The %CPU field could be >99, so (\d{1,2}\.\d) will not match '100' or higher. It expects a decimal like 2.3.
The ps output for %CPU is integer (not decimal) for large values.
The line starts with the process name, plus spaces.
Fixed with:
$l =~ s/^\s+//; # remove leading spaces
my @fields = split /\s+/, $l, 11;
my ($user, $pid, $cpu, $memory, $vsz, $rss, $tty, $stat, $start, $time, $command) = @fields;

The script tries to match lines with this regex in the read_logs function:
($user, $cpu, $memory, $command) = $l =~ m{^(\w+)\s+\d+\s+(\d{1,2}.\d)\s+(\d{1,2}.\d).\d{1,2}:\d{2}\s+(.)$};
