Hi all: You guys may be aware that I have checked the patch into trunk earlier today:
http://sourceforge.net/apps/trac/ganglia/changeset/2351 Thanks to Neil and Peter for all the hard work and Brad for reviewing it. If I could make just one comment: right now if I run gmond in debug mode, it shows that the sFlow metrics are actually spoofed gmond metrics. Is there a way to make it so they are labelled sFlow metrics? Perhaps we should start a separate thread to discuss Kostas' idea of having a pluggable interface for metric sources. With sFlow support, gmond can now handle both gmond sources and sFlow sources. With a pluggable interface, we could in the future be able to aggregate data collected by other tools, such as collectd, collectl, etc. The possibilities are endless. What do you guys think?
