Hello,

I am migrating from pve 4.0 to pve 4.4.

I already have one pve 4.4 node and it looks like on this node I can not see the week, month and year average.

Will I loose all this graph data ?

Thanks.

Hello,

Is there a way to migrate the graphs ? I wouldn't like to loose the information if there is a way to keep it.

I checked it again and I can not see the graph history from the node that has version 4.4.
 
is your pve 4.4. node new? if yes -> it will take some time before you can see the data
on an upgrade, the graph data will not be deleted, so you should be fine

the rrd dbs are under /var/lib/rrdcached/db if you want to backup those (but should not be necessary)
 
Thank you for your reply @dcsapak

Lets see if I can explain the issue with some more detail.

I have a three node cluster with the nodes pve2, pve3 and pve4. They used to be proxmox 4.0 but now I have updated two of them so I have the following versions:

pve2 and pve3 are proxmox 4.4
pve 4 is proxmox 4.0

When I go to the web interface of the node pve4 (proxmox 4.0) and I check the graphs for any node, I can see data for the last 7 months.

When I go to the web interface of the node pve2 (proxmox 4.4) and I check the graphs for any node, I can see data for the last 2 months.

Why can I not see the last 7 months of data from proxmox 4.4 ?

Thanks.
 
could you post a screenshot of this please?
 
hi, yeah i saw it, i will look into it why this is the case, but as far as i remember it, this should definitely work, because both graphs get the data from the same source (namely /var/lib/rrdcached/db )
