[collectd] VMEM graph not working?

[Mirko Buffoni]

Hi everyone,

I was experimenting with collection.cgi and noticed that VMEM
graphs aren't displayed at all.
rrdtool dump of the archive shows that data are present.

Further inspection in collection.cgi shows that no $GraphDefs
definition is present for any vmem type.
Is this known?  Can you point me to any $GraphDefs for vmem
plugin?  I'm not yet fluent with RRDTOOL to create a GraphDef
on the fly.

Thanks in advance

Mirko
