looks good.

It should be on the box which hosts sflowtool (fwiw, inex also runs 
ixpmanager front-end installation, database and sflow collector on 3 
separate devices).

The contents should be based on the example ixpmanager.conf at the 
following URL: https://docs.ixpmanager.org/features/sflow-p2p/

We use 2048 on 1G boxes and 8192 on 10G/100G boxes.  Probably this could 
do with some tuning.
