[ixpmanager] Assistance Needed with P2P Graph Issue in IXP Manager

[ozikat]

Hi,


Can you also share you config for sflow configuration?

The config file need to be manually created and it's in 
/usr/local/etc/ixpmanager.conf


At the same time just to confirm the sflow is running, can you do 
command below?


ps axuwww | grep sflowtool


Thanks.
