Use tcpdump on the client to see if it's actually sending data:

It may also be worth your while to yum update the Cent7 box if you haven't already. There were some weird IPv6 --> IPv4 listener translation mumbo jumbos happening that didn't work properly in earlier versions of Cent7. Updating to the newest kernel fixes these in my experience.

Hi all,

Just to give an update.

After trying to update CentOS to latest version and trying to check other things, I finally figured out how to make it work. fprobe wasn't running at all before, and I needed to include -n option and choose the newest version instead of the default (5).
After doing this I was able to verify that fprobe was running under ps aux and after a few minutes I can finally see the graph.

Thanks a lot for everyone's suggestions! Took me a couple of days but finally got it to work.

I've never seen that required before. Glad it's working though.

Glad to hear it worked!

I'm going to close this topic, thanks for the update.
