We directly query the kvm process using the  'query-blockstats' qmp command:


use strict;
use warnings;
use PVE::QMPClient;
use Data::Dumper;

my $vmid = shift || die "no VMID specified\n";

my $qmpclient = PVE::QMPClient->new();
my $res = $qmpclient->cmd($vmid, { execute => 'query-blockstats'});

print Dumper($res);
