I want to see smart data for hard drives but when I run smartctl -a /dev/sda it shows /usr/sbin/smartctl: Permission denied.

Tried with sudo etc but not working.
 
Cannot reproduce that, installed smartmontools via:
apt-get install smartmontools

and then your command is working just fine:

Code: 
root@XXX:~# pveversion 
pve-manager/4.0-59/a1588972 (running kernel: 4.2.3-2-pve)
root@XXX:~# smartctl -a /dev/sda
smartctl 6.4 2014-10-07 r4002 [x86_64-linux-4.2.3-2-pve] (local build)

How did you install it? And do you run it as root?
 
Seems you are using the Proxmox VE 4.0 OVH installation template?

If yes, please open a ticket on OVH and ask why the set a custom permission - looks like a bug to me on their installation image.

Yes its OVH installation Template...can I change permissions by myself, because I am administrator of server and have full access to everything in Proxmox and Server with IPMI.

This would take days until they reply...support is not fast as you think and dont want to create new troubles to get my server accessed to them with root user etc, I thought you would help me how to change permission and make a smart test because I need to check my health of my drives.
 
I tried a lot to make smartctl to work in Nodes.pm, but I always got permission denied.
So I decided to go a different path.
I created a service that gets the temperature from HDD using smartctl. The value is placed in /run/hddtemp/sda.temp.
Then in Nodes.pm I do this:

Perl: 
sub read_temp {
    my ($dev) = @_;                           # e.g. 'sda'
    my $path = "/run/hddtemp/$dev.temp";
    return 'N/A' unless -e $path && -r $path;
    open my $fh, '<', $path or return 'N/A';
    my $v = <$fh>;
    close $fh;
    defined $v ? do { chomp $v; $v eq '' ? 'N/A' : $v } : 'N/A';
}

        $res->{HDDtemperatureSda} = read_temp("sda");

And in pvemanagerlib.js
Code: 
        {
            itemId: 'HDDtemperatureSda',
            colspan: 2,
            printBar: false,
            title: gettext('HDD Temperature'),
            textField: 'HDDtemperatureSda',
            renderer: function(value) {
                const n = Number(value);            // value is a string
                if (Number.isInteger(n) && n > 0) {
                   myValue = value;
                } else {
                    return '/dev/sda: N/A';
                }

                return `/dev/sda: ${myValue} ℃`;
            }
        },

This is how it looks in proxmox:
