Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Hello All,
I just wanted to follow up on the discussion we started a couple of weeks
ago concerning an analytics framework for NiFi metrics. Working with Andy
Christianson and Matt Burgess we shaped our ideas and drafted a proposal
for this feature on the Apache NiFi Wiki [1] . We've also begun
implementing some of these ideas in a feature branch (which is work in
progress) [2]. We’d appreciate any questions or feedback you may have.
Thanks,
-yolanda

Re: Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Posted by Robert Fellows <ro...@gmail.com>.
Mark and Yolanda,
I submitted the PR I mentioned yesterday for the UI changes that surface

https://github.com/apache/nifi/pull/3660
Thanks,
Rob

Re: Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Posted by Yolanda Davis <yo...@gmail.com>.
Hi Mark and Rob
Mark thanks so much for the info on your work and Rob thanks for jumping in
on the UI! I just wanted to add, Mark, that looking at your branch I think
we also may have some opportunities to exchange notes or collaborate on the
backend as well. The work in the feature branch is still in progress (with
some decoupling to ensure we can allow flexible configuration of models).
Please feel free to review and leave comments under the parent JIRA. At
the same time I'll take a deeper dive on your branch and perhaps we can
exchange notes on potential areas for improvement/collaboration if it makes
sense?
Thanks Again,
-yolanda

Re: Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Posted by Robert Fellows <ro...@gmail.com>.
Hey Mark,
I've started working on some UI based on the initial commit for this
proposal. What you have done and what I am working on have a bit of
overlap, but not much.
I'm working on getting the predicted count and bytes into the existing
connection metric display that is already on the canvas. The only overlap
looks like it might be in the
Summary table. I plan on adding a PR for my additions hopefully tomorrow.
Maybe once it is up we can discuss how we bring the them together where it
makes sense?
This is the main JIRA case: https://issues.apache.org/jira/browse/NIFI-6510
And this is the subtask that I am working toward:
https://issues.apache.org/jira/browse/NIFI-6568

Hi Yolanda,
I've been working on a feature that appears to possibly overlap with the work you are pursuing. Perhaps we should see if/should we try to coordinate our efforts. I've been updating NiFi to predict the time to queue overflow for both flowfiles and bytes and displaying that information in the GUI. For the initial attempt, I’ve been using a simple model of straight line prediction over a sliding window of 15 minutes to predict when flows will fail. This estimate is then displayed on both the NiFi Summary page under the connections tab and in the status history graphs. Below are examples of what would be displayed to the user.
[cid:image001.png@01D55696.E4CCD550]
The Connection tab contains a new column on the right that displays the prediction for both flow files and data size. The user can select a maximum time at which specific times are no longer displayed. In this example, if the prediction lies beyond 12 hours then the display simply indicates that the flow is greater than 12 hours away from failure at the moment.
[cid:image002.png@01D55697.2C8AC500]
This display graphs the prediction for byte overflow over time. Note that if the estimate is greater than the user provided maximum value of interest the graph maxes out at that time, effectively indicating no overflow concerns.
[cid:image003.png@01D55697.965C27D0]
A similar display for flowfile count is displayed as well.
The current state of work can be found at https://github.com/jmark99/nifi/tree/time-to-overflow
I welcome your (or any others) feedback on this effort.
Thanks,
Mark

Subject: Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Hello All,
I just wanted to follow up on the discussion we started a couple of weeks ago concerning an analytics framework for NiFi metrics. Working with Andy Christianson and Matt Burgess we shaped our ideas and drafted a proposal for this feature on the Apache NiFi Wiki [1] . We've also begun implementing some of these ideas in a feature branch (which is work in
progress) [2]. We’d appreciate any questions or feedback you may have.
Thanks,

RE: Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Posted by "Owens, Mark" <jm...@evoforge.org>.
Hi Yolanda,
I've been working on a feature that appears to possibly overlap with the work you are pursuing. Perhaps we should see if/should we try to coordinate our efforts. I've been updating NiFi to predict the time to queue overflow for both flowfiles and bytes and displaying that information in the GUI. For the initial attempt, I’ve been using a simple model of straight line prediction over a sliding window of 15 minutes to predict when flows will fail. This estimate is then displayed on both the NiFi Summary page under the connections tab and in the status history graphs. Below are examples of what would be displayed to the user.
[cid:image001.png@01D55696.E4CCD550]
The Connection tab contains a new column on the right that displays the prediction for both flow files and data size. The user can select a maximum time at which specific times are no longer displayed. In this example, if the prediction lies beyond 12 hours then the display simply indicates that the flow is greater than 12 hours away from failure at the moment.
[cid:image002.png@01D55697.2C8AC500]
This display graphs the prediction for byte overflow over time. Note that if the estimate is greater than the user provided maximum value of interest the graph maxes out at that time, effectively indicating no overflow concerns.
[cid:image003.png@01D55697.965C27D0]
A similar display for flowfile count is displayed as well.
The current state of work can be found at https://github.com/jmark99/nifi/tree/time-to-overflow
I welcome your (or any others) feedback on this effort.
Thanks,
Mark

Subject: Re:[EXT] [DISCUSS] Predictive Analytics for NiFi Metrics
Hello All,
I just wanted to follow up on the discussion we started a couple of weeks ago concerning an analytics framework for NiFi metrics. Working with Andy Christianson and Matt Burgess we shaped our ideas and drafted a proposal for this feature on the Apache NiFi Wiki [1] . We've also begun implementing some of these ideas in a feature branch (which is work in
progress) [2]. We’d appreciate any questions or feedback you may have.
Thanks,
