Yes, this was probably more like a threshold, we also found that the admin
work needed was quite big, and wanted to refocus our efforts to development.

The goal is to allow people with reasonable web frontend background to
build their custom dashboard in 2 or 3 days.
Each project does not require that, this is why we try to have some generic
It is much harder to make generic tools than to make specific ones. We had
a lot of issues with console and grid, which was working great with some
people, but for other was not , because of the different SCM, or the
different pipeline setup.
That is why Buildbot is a framework to build specific workflows.
For people with lots of builders, the design trade-off will be different.
If we manage to build a new dashboard for people with lots of builders, I
think this would be even better.
Doing first a specific one is a good first step, then we can show it to
others and step backward to see how it can be useful to them.

I am not sure exactly what you have in mind.
The grid view has builder tag support: https://nine.buildbot.net/#/grid
You could setup your builders with a tag per port, and then use this kind
of filtering in order to have a per port view.
We would need to change the UI for grid view, because obviously the current
UI will be unusable for thousands of tags.

The examples we have are the console/grid/waterfall plugins.

I think we first need to have a sketch of the dashboard of how you see data
is displayed. maybe several sketches with options, and then I can help to
translate that with more technical details. This is also good to let some
part of the technical details to the student proposal for easier

Yes, for us it was very hard to keep student around, we had only one who
did contribute from time to time for another 3-4 months.

Well GSoc is supposed to help for that. I believe we can tag the project

I think this good be sorted out by the student in the proposal build phase.

That is why it is a bit harder. It is more like a research task were most
of the work is finding out how to do it, then doing it is relatively
straighforward once you found a solution.

So this is a very good use of co-mentoring I can help with the technical
issue, and you work on the goals.

Yes, lets start it.
Like said earlier, having a drawing of what would be a good dashboard in
your view is a good start, and then I can add some details on which data
needs to be fetched and how they need to be gathered.
