The Windows UUID appears for me, but that's from a Windows7 OS. Maybe we
would need to look in a different place on XP. (The Linux port falls back on
the UUID of the first local disk if it can't get a UUID for the whole system,
so maybe something similar to that would be acceptable as a work around.)
Please raise this question on host-sflow-discuss.

The specs on sflow.org cover this, but basically it consists of
{IPAddress,dsClass,dsIndex} where the IPAddress can be a v4 or v6 address, and
the dsClass tells you if the dsIndex is referring to an interface, a physical
entity or a logical entity (such as a VM or application). Conceptually I
think of each datasource as being one "observation point" in the system. From
ganglia's perspective it's probably best to treat it as an opaque string, and
just use it to know, for example, that a particular VM is running on a
particular hypervisor.

OK. I'll wait for Brad to comment.

OK.

I really don't know my way around gmond, and that sounds like it might be a
far-reaching change.
