Update traffic data format

[baransu]

Netflix/vizceral#59 got merged into Vizceral recently. It adds entryNode property and removes requirement for INTERNET node. It also allows two way message passing in our cluster view.

Things we have to change to update to version 4.4.0:

• change focused -> focusedChild
• for every graph add entryNode property describing graph entry node
• replace one, one way connection to entryNode with warnings with two, one way connection without it

It is related into traffic view, right? I'll look into it as soon as I'm finished with Elixir stuff 🙂

Does this update mean that there won't be INTERNET node, and we will have bi-directional particles flow?

[baransu]

Correct :)

Very cool.

BTW, in one of the Vizceral examples I saw force directed graph layout demo. Can we give it a try in the second level, where we render message passing?

[baransu]

I'll try to look into it.

@arkgil @michalslaski @mentels This change it crucial for us right now because a lot of people are trying EPL in recent days. These changes will fix no nodes in /traffic view when only one node in cluster. After getting this resolved on both front and backend we should release new version asap.

I'll try to look into it this evening 🙂

@arkgil Are going to look into it today or can I?

[arkgil]

You can always look into issues, I'd be happy to help :) I don't have much time lately, sorry for delay.

EDIT: but I'm looking into it right now. Although extra pair of eyes does not harm anyone 😄
