I ran the sample program you have given . But it takes long time to return me
the data sets.
real 0m3.137s
user 0m2.580s
sys 0m0.140s
I have a question whether this request going from the unix domain local socket
on the host or going from HTTP/ tcp.
Other is there some API implemented for Python for extracting the metrics in a
simpler manner.
All I want to read is the VIF read/ write data.
Please guide.

Hi Abhijeet,
As Alberto mentioned, you should be using the RRD interface rather than looking
at the VIF metrics. There's documentation about that
on the wiki:
