>>Yes, we only change the broadcast name. 

But if I only change the broadcast , it'll recreate an new empty rrd ..?

$data = "$d->{uptime}:$d->{name}:$template:$ctime:$d->{cpus}:$d->{cpu}:" .
        "$d->{maxmem}:$d->{mem}:" .
        "$d->{maxdisk}:$d->{disk}:" .
        "$d->{netin}:$d->{netout}:" .
        "$d->{diskread}:$d->{diskwrite}";

PVE::Cluster::broadcast_rrd("pve2.3-vm/$vmid", $data)


or do you want:

$data = "$d->{uptime}:$d->{name}:$ctime:$d->{cpus}:$d->{cpu}:" .
        "$d->{maxmem}:$d->{mem}:" .
        "$d->{maxdisk}:$d->{disk}:" .
        "$d->{netin}:$d->{netout}:" .
        "$d->{diskread}:$d->{diskwrite}";

PVE::Cluster::broadcast_rrd("pve2-vm/$vmid", $data)

$data2 = "$template";
PVE::Cluster::broadcast_rrd("pve2.3-vm/$vmid", $data2)

we keep writing values to old files. I do not want to generate a new file.

Yes, we only change the broadcast name.
