Comment 2 for bug 1995805

I actually found a way to fix this by modifying the /usr/lib/python3/dist-packages/landscape/sysinfo/load.py file to the following:

import os
from decimal import *

from twisted.internet.defer import succeed

class Load(object):

    def register(self, sysinfo):
        self._sysinfo = sysinfo

    def run(self):
        self._sysinfo.add_header("System load", str(Decimal(os.getloadavg()[0]).quantize(Decimal('.00'))))
        return succeed(None)

And now I get the correct info:

$ landscape-sysinfo
  System load: 0.86 Processes: 335
  Usage of /: 51.0% of 211.67GB Users logged in: 1
  Memory usage: 12% IPv4 address for eth0: 10.0.0.100
  Swap usage: 0%
