sflowtool is not showing any samples output

[kishanps]

Need some help where I am not seeing any sflow samples output in the sflowtool. Below is the hsflowd config file and I do see takeSample outputs in the debug file but just nothing on the udp port. What prevents sflow samples from being sent out when they made it all the way upto the takeSample() ?

The only error I see in the debugs are the 'Get SIOCGIFADDR' failed errors for every interface since there is no IP assigned to them. Any debugging tips would be helpful.

What do you have in /etc/hsflowd.conf?
And what OS is running (/etc/os-release)?
And did you build both sflowtool and hsflowd from sources?
