Hi Marco,

Per-VLAN graphs are only available with the sflow backend.

Do you have this configured? [see: https://docs.ixpmanager.org/grapher/sflow/]

If you do not have it configured, was there a link to this? (That would be a bug as there should be no lines if the graph type is not available).

Barry

[rfc1036]

I cannot use sflow due to hardware limitations so it is not configured, but I consider any page failing with error 500 a bug.

I do not think that there are links, but somebody tries to access the public URLs anyway.
