Subject Network Usage
Date Thu, 29 Nov 2012 20:34:11 GMT

I'm interested in how network usage is obtained by CloudStack.  I've 
been unable to find much documentation on the matter.  From research the 
method used for basic and advanced zone is different.

For basic it appears to be with sFlow and using the API calls of 
addTrafficMonitor, deleteTrafficMonitor, listTrafficMonitor.  There 
doesn't appear to be an UI element for this and it must be used via 
API.  Is there a suggested open/free implementation that I could setup 
for test purposes?

For advanced, it seems to be from the virtual router and iptables 
NETWORK_STATS.  However, in my advanced zone, I am not seeing those 
counters rise.  I've found even less documentation on this side.  I may 
of mis-configured things, but I have no documentation to verify against.

Can anyone point me to a document that describes the process for both zones?
