Hello All,
Here is some background on the sFlow support that has been added to gmond
in the development branch:
http://blog.sflow.com/2010/10/ganglia.html
An sFlow agent is extremely lightweight, since sFlow monitoring is
typically used in embedded environments where resources are constrained:
switches, routers, firewalls, hypervisors etc. The addition of sFlow
support to gmond allows metrics to be collected from these environments
where the installation of a gmond agent is often not possible.
This initial implementation of gmond/sFlow decodes and populates the core
set of Ganglia metrics, but future versions could decode additional sFlow
structures. For example, sFlow reports on virtual machine statistics (based
on libvirt), however the challenge is deciding how to incorporate the
additional metrics in the Ganglia data model and in the UI:

There are currently sFlow agents for Windows, Linux, Xen, XCP, XenServer
and KVM/libvirt.
Please reply to the list with any comments and suggestions.
Cheers,
Peter
