ok got it!

one other question, if I try to add template value just after ctime, and I increment skip 

$data = "$d->{uptime}:$d->{name}:$ctime:$template:$d->{cpus}:$d->{cpu}:",


and that all nodes have not yet updated their packages, I think I'll make bad things.

if node1 have field4 template, and node2 have field4 maxcpu,  node1 will see all field4 maxcpu as template values.


Maybe it is better to do a new rrd like you suggest ? (/pve3/xxx=). (But I really only need it in memory)

The idea was that we simply do not add any values. If we really need to add something, 
we simply use a new file (maybe called .../pve3/xxx).

file: pve-cluster/data/src/status.c 
function: update_rrd_data() 

search for 'skip'
