Not a valid vname

[geoffg]

I have a bunch of interfaces on switches, using the generic snmp interface template and virtually all of them have this message since the 1.0 update, anyone have any idea how to fix this?

Rrdtool 1.3+ is required, not optional.

[geoffg]

i'm using 1.5, I think, which is default in Ubuntu 16.04

[Osiris]

What Cacti version. If not 1.1.3, please upgrade. It's a simple thing.

[geoffg]

I'll try 1.1.3, but it's been happening since 1.0, through all the updates. I'll report back shortly.

Ok, I have 1.1.3 and I am still getting these errors. They didnt seem to appear in any version prior to 1.0

Post the debug information on the Graph page. Need the rrdtool syntax.

RRDTool Says:
ERROR: undefined vname 

[Osiris]

8 lines up from the bottom, the AVG GPRINT lacks a data source.

[geoffg]

This one?
GPRINT::AVERAGE:'Average\:%8.2lf %s' \

if so, how can you tell?

I also have hundreds of these in just normal snmp interface templates..

[Osiris]

:: is not valid. There needs to be a vname between them.

[geoffg]

ahhh thanks.. awesome. Found the solution was I had ticked the box which doesnt use a unique name for each graph in the template

After so many years, this post is gold.
Thanks for your help.
