Make it clear which nodes have incoming connections and which nodes have outgoing connections when you have a node selected

[tomwilkie]

Something like this (when viewing the detail panel):

I think this will make it super obvious what containers / process etc something is talking to, and what container / process is talking to it.

[tomwilkie]

If you combine this with some kind of semantic colouring, this might be interesting way to answer the question "why is this container sick".

What do you think @davkal @foot @paulbellamy?

[paulbellamy]

I would be more in favour of this if "incoming" vs "outgoing" was more than a guess, but even determining what that means is tricky.

conntrack'd connections have direction: #539

[davkal]

I like it, though arrow offset will have to be calculated differently for all new shapes.

[tomwilkie]

This also came up with Darren from Rancher.

But most connections are not conntrack'd (only short-lived ones are), no?

[tomwilkie]

Actually almost all connections are conntracked, the set of ones detected
by proc spy and not by conntrack is almost nil.

#875 (comment).

Edge direction is now even more meaningful: we get them from conntrack. @davkal do you think this is something we could have a go at (even without arrow heads)?

[pidster]

+1 for adding a visual indicator for direction, to edges. #872

How is this different from #872?

This is talking about the "selected" mode, where as #872 is in the general canvas.

Also this suggestion is about changing the location of the nodes (incoming at the top, outgoing at the bottom) when you select a node, whereas #872 is just about adding a direction indicator for edges on canvas.

I like that, and it's something that could be done independently from tackling the thorny/controversial issue of adding arrow heads.

Related to #1636

This is mostly accomplished by #2317. Concepts involving re-arranging the nodes were unsuccessful, as it lead to very unbalanced "sides" of the diagram which lead to difficult to read diagrams. Closing.
