Ets cluster view #63

Closed mkacper closed 7 years ago

mkacper commented 7 years ago

This PR introduces ETS cluster view. It appears as a new tab in the web UI. The view shows all nodes in the cluster with basic infromation about ETS tables on a particular node.

@mkacper I've conected two nodes together with net_kernel:connect('a@127.0.0.1'). (and connect_node) but erlangpl shows warrning in console:

=WARNING REPORT==== 21-Jun-2017::14:54:47 ===
global: 'erlangpl@127.0.0.1' failed to connect to 'a@127.0.0.1'

Why can be that? Am I doing something wrong?

EDIT: They are perfectly connected within /traffic view.

It's not related to this PR but previously we were displaying erlangpl node only in development mode but after release it wasn't part of the cluster. Did something changed in this matter?

mkacper commented 7 years ago

@Baransu This warning is normal :) I haven't figured out yet why it is showed. What does the /ets view show in your browser? I've followed the steps you described and ets cluster view seems to work fine.

Here is the proper view: epl_ets_cluster_view

When it comes to displaying erlangpl node in the cluster view in /traffic section I have not changed a way of creating Vizceral map for \traffic view. I've made a release from master branch and erlangpl node is also displayed in /traffic view. Asking your question - I haven't got a clue if somethig changed in this matter or not.

Thanks for your engagement! :)

EDIT: Something is wrong with ets cluster view when erlangpl is started from script. I will try to fix it.

baransu commented 7 years ago

I have 3 nodes in cluster. Every one connected with net_kernel:connect(node).

mkacper commented 7 years ago

Thanks for point the issue :) As I said in the previous comment something goes wrong when erlangpl is started from erlangpl script. I am working on it right now.

Sorry, I didn't saw your edit. Also, did you managed to fix with switching between etc and traffic view?

mkacper commented 7 years ago

@Baransu

did you managed to fix with switching between etc and traffic view?

Yes, I did. It seems to work nice :)

Please try the \ets view now. Does it work correctly?
