Feature request: Proper progress updates for loop nodes

[qqilihq]

Is there any chance of getting a proper progress bar when using the loop nodes (especially the "Chunk Loop Start")? I'm currently checking the flow variables during long executions, but having the current progress within the workflow below the node would make things much more convenient.

Regards,
Philipp

unfortunately 4years later there is still no progress in this progress matter…would be very handy indeed

Hello @adaptagis,

will add yours and other requests to existing ticket (internal reference: AP-3238).

much appecciated and for sure a big gain to the Knime community!

Good evening,

while writing on a blog post I happen to have found this feature request. You might want to leverage the example workflow I created to track loop execution in detail.

Monitor Loop Progression in the Knime Console - Example Workflow

Hi KNIME community! I wanted to share a helpful method, including an example workflow, for tracking loop progress in KNIME, which is especially useful in long-running workflows or when using Parallel Chunk Loop Nodes. This approach uses a Java Snippet node to create a console-based progress bar that updates on each loop iteration. With this progress indicator, you can: Monitor loop progress in real-time. Debug potential bottlenecks. Gain insight into resource distribution in parallel executi…

PS: There is also another similar feature request. You might draw some ideas from that and my example so we can consolidate all and draw attention of the developers to this request

Loop execution progress

It would be nice to have a loop execution progress indicator when a loop is being executed. When I use Group Loop Start, the number of groups should be known (right?). In the Loop End node this is Iterations, if I am correct. Would be really nice to have an indicator saying how many of the intended iterations have been processed when executing, so I don’t have to zombie-gaze at the screen until it is suddenly finished. #WalkToTheCoffeeMachine

Hi @mwiegand

Did you check the Node Annotator nodes? I used them to create a component to track the loop progress as wel.

Feature Request around Loops

Hi @richards99 Your question inspired me to make the Loop Progress a little bit more user friendly. I created 3 components to track the Loop Progress. [afbeelding] Since there is always room for improvent. I combined those 3 components into 1. You can find the components on My KNIME Hub: gr. Hans

HI Hans,

thanks for the addition. What these nodes I believe miss is the persistence of a real log. Upon re-execution the node annotation gets updated. It also removes the original annotation which I regularly use for documentation purposes.
