templated data source/graph issue.

[GregSE]

Hi.
Just recently instsalled new version of cacti (have parallell 0.8.XXX) on a RPI.

I have used cacti for quite some time and setup templates for snmp polling and some other stuff.
In this version I can't seem to set up a data source and graph template that actually generates a graph.
I only get -nan and an empty graph on both my wget-script DSs and my SNMP DSs.
If I create a graph based on the "SNMP-host OID template" I manage to get 1 graph for host x.
But graphs 2 and on end up with "nan".
If I run a DS check, I get an invalid output but I get a correct value when running snmpget in the CLI.

Going mad over this....what am I doing wrong???

Tnx!

You can do a few things. First, to see the results from polling, out the problematic device into debug mode, second verify you have valid poller items.
