There is any way i can add memory monitor of guest vm

my code for example

#!/usr/bin/env python

import libvirt
from libvirt import libvirtError
import time

def request_cred(credentials, user_data):
for credential in credentials:
if credential[0] == libvirt.VIR_CRED_AUTHNAME:
credential[4] = 'test'
elif credential[0] == libvirt.VIR_CRED_PASSPHRASE:
credential[4] = 'dddddddd'
return 0

auth = [[libvirt.VIR_CRED_AUTHNAME, libvirt.VIR_CRED_PASSPHRASE], request_cred, None]
conn = libvirt.openAuth('qemu+{0}://{1}/system'.format('tcp','127.0.0.1'), auth, 0)
#conn = libvirt.open(optional_params['conn'])
guest = 'guest'
vm = conn.lookupByName(guest)
""" test with running vm """
memstats = vm.memoryStats()
percent = memstats['rss'] / memstats['actual'] * 100
pcentCurrMem = max(100.0,min(percent, 0.0))
print(percent)
print(int( float(int(memstats['rss'])) / float(int(memstats['actual'])) * 100 ))
time.sleep(1)
vm.setMemoryStatsPeriod(5, libvirt.VIR_DOMAIN_AFFECT_LIVE)
memstats = vm.memoryStats()
print(int( float(int(memstats['rss'])) / float(int(memstats['actual'])) * 100 ))

But the usage of memory the same 99% or 101%
how can i solve this problem

I have add that information to stats as graph for vm. Have you see that? You can search rss in instance/view.py and vrtmanager/instance.py
