Re: UI: flow status and counters feedback

[Andrew Grande]

Alright guys, do we have enough consensus to start filing jira work items?

 Andrew,

 Thanks for the feedback on the status bar. Separation between each item
 helps but realize after your comments how it can not feel like a single,
 cohesive group of items. We could probably tighten things up a bit.

 I think another part of this that could help would be to address some
 of the discussion around awareness of stats updating. Being able to call
 more attention (without being too intrusive) when stats change could help
 ease some of the burden of having to routinely scan the status bar to look
 for changes.

 Also related, I would like to see us get a tooltip that is seen when
 you hover anywhere on the status bar. That tooltip would provide more
 descriptive text about what each item means. It would help new users learn
 as well as provide detail and follow-on action when something is alerted.

 Let's see what others think and then I can work on filing a jira to
 capture thoughts.

I like the tooltip addition of yours.

For more interactive feedback on the canvas I can immediately think of 2
items.

1. Indicator for when backpressure was configured on a connection (although
it's now always added by default, maybe less useful).

2. Changing the color of a connection when backpressure has engaged could
go a long way. Can go further, gradient color based on how close the
connection backlog is to triggering the backpressure controls. Immediately
highlights hotspots visually.

Andrew,

Thanks for the feedback on the status bar. Separation between each item
helps but realize after your comments how it can not feel like a single,
cohesive group of items. We could probably tighten things up a bit.

I think another part of this that could help would be to address some of
the discussion around awareness of stats updating. Being able to call more
attention (without being too intrusive) when stats change could help ease
some of the burden of having to routinely scan the status bar to look for
changes.

Also related, I would like to see us get a tooltip that is seen when you
hover anywhere on the status bar. That tooltip would provide more
descriptive text about what each item means. It would help new users learn
as well as provide detail and follow-on action when something is alerted.

Let's see what others think and then I can work on filing a jira to capture
thoughts.

UI: flow status and counters feedback

[Andrew Grande]

Hi All,

I'd like to provide some feedback on the NiFi 1.0 UI now that I had a
chance to use it for a while, as well as pass along what I heard directly
from other end users.

Attached is a screenshot of a status bar right above the main flow canvas.
The biggest difference from the 0.x UI is how much whitespace it now has
between elements. To a point where it's not possible to quickly scan the
state with a glance.

Does anyone have other opinions? Can we adjust things slightly so they are
easier on the eye an have less horizontal friction?

Thanks!
Andrew
