[ui]: initial proof of concept interface using butler

[TristanCacqueray]

This change implements the following integration between monocle and butler:

• A sample app to perform query.
• Butler's display websocket served along the monocle api.
• Run butler context using monocle logging system (or the otherway around).
• App storage using a custom elasticsearch index.

@morucci here is a little poc to integrate butler. It's still missing proper logging and storage, but for now, if you go to "/view", then you'll get a butler app that makes a query :-)

When I access /view route my browser keeps trying again and again 'ws/htmx' but server side I see "59786ms error <1>init Butler.Display.WebSocket:91 Unknown websocket session {"session": null}" at each connection attempt.

Do you have oidc auth enabled and you are not logged-in the regular ui?

[morucci]

That was it (my OIDC config) now I see "Change count: 0" which is expected I guess as I don't have any data :)

[morucci]

Then I'm wondering if, as a follow-up of this POC, that could be an opportunity to move the search author implementation (which is already via htmx) to the butler/ws ?

[TristanCacqueray]

Well that's the reason I made this prototype, so that we can experiment with such UI implementation :) My goals here are two folds:

• Implement a grafana-like interface, where user can create and share dashboards composed of individual panels.
• Improve butler to smooth such integration, so that we could for example, use it for zuul-weeder as well.
