TrendMiner 2021.R3.0

December 30th, 2021

Version 2021.R3.0 contains the following new features and improvements:

Getting ready for some exciting new capabilities in 2022

At the end of the year, many companies look back at what they have accomplished during the past year. With this end-of-year release, next to putting the icing on the cake for some of the new capabilities that we released in 2021, we are mainly focusing on getting ready for the exciting new capabilities that we will be bringing to our customers next year

  • In the run-up to the full launch of TrendHub NextGen, which will become the standard interface in the first major release of 2022, we are now introducing a new look and feel for ContextHub and DashHub for a clear, uniform layout with more efficient use of screen estate
  • In preparation for the Secure by Default and Secure By Design approach for our TrendMiner platform, we are updating some platform settings To smoothen the upgrade path for the new security backbone we are integrating in our platform
  • In anticipation of additional analytics capabilities on context items - representing process events such as batches, campaigns, defects, or others - we are extending the connectivity support for contextual data sources, i.e. support connecting to multiple OSIsoft PI Event Frame databases, as well as including various performance improvements for large ContextHub result sets

Application Enhancements

  • Improved tag-search performance for customers with very large numbers of connected tags
  • Suggestions for recently used tags/views when visualizing context items in TrendHub NextGen
  • ContextHub table column widths are saved as part of a ContextHub view
  • Improvements to DashHub’s current value tile for plotting tags with slow update rates
  • Focus plot improvements for TrendHub NextGen
    • Overlapping context items on the focus plot are now combined in a list to be able to choose the desired one. Similar behavior as used on the Gantt chart in ContextHub.
    • Scroll zooming on the focus plot will now zoom in and out on the location of the mouse pointer.
    • Panning possibilities added to the X-axis of the focus plot. Depending on the state of the focus plot's lock option, this results in increasing the time period or moving the time period into the future or past.
  • TrendMiner version in user drop-down: in TrendHub NextGen, ContextHub and DashHub, the user can consult which version of TrendMiner is currently installed and being used
  • Admin: Improved insights in the integration-status of OSIsoft PI AF data sources, both for asset capability (sync Asset Frameworks) as well as context capability (sync Event Frames)
  • Miscellaneous security improvements

Bug fixes

  • We have improved the Recommendation Engine to make looking for candidate tags less resource-intensive, allowing running searches that contain a higher number of tags without hitting limitations on the system.
  • When the context item created by a monitor failed due to hiccups with our security service they were are also considered monitoring malfunctions, causing the monitor going to system-disabled. In these cases, the monitor won’t be system-disabled anymore.
  • When the trigger of a fingerprint monitor is deleted, the monitor will go to system-disabled, and will remain disabled after running the health check (instead of incorrectly re-enabling the monitor as a match fingerprint)
  • Monitors with malfunctioning context item creation actions will now also be system-disabled and a notification will be sent to inform the user.
  • Restricting Monitoring configuration API to admin role. Specifically how many active monitors we allow per user.
  • We fixed the issue with dashboards containing an old value tile with a timestamp.
  • Timestamps of chart exports and search results export are again formatted as custom Timestamps instead of text when opening in Excel.

Known issues

  • Updates from 2021.R2.1 to 2021.R2.2 to 2021.R3.0 might result in a broken ConfigHub task queue. In case this happens, please contact TrendMiner support​​.
  • Cross asset value based search is currently not supported (and blocked) for string tags (i.e. digital tags for which no numerical value mapping exists on the historian). Digital tags for which a numerical value mapping exists on the historian are supported.
  • After restoring a backup the tm-zeppelin and the tm-zementis service need to be restarted manually.
  • Scooter values may change when zooming in after adding the scooter. This is due to the fact that scooters currently interpolate the data points on the chart.
  • The back button of the browser does not correctly restore the panel state.
  • When calculated tags are deleted, they cannot be created with the same name again.
  • Cloning a notebook will result in a copy of the notebook. The paragraphs of the copied notebook are still interlinked with the paragraphs of the original notebook. The "linked" paragraphs of both notebooks may be refreshed/updated based on the other notebook resulting in undesired behavior. It is advised to copy/paste your code manually for now.
  • Renaming a tag in the tag builder is not supported if the tag is linked to a Context item.

Important

As from the 2022.R1 onwards, we will drop active support* for Internet Explorer 11 browsers, following Microsoft's recommendation to only use Internet Explorer for compatibility with older sites and applications. Ending support for IE 11 will allow us to use modern web practices to improve performance and user experience as we continue adding new features. Support for Microsoft Edge browser has been added instead.

* users will still be able to use IE11 with TrendMiner, but new features might no longer work + IE11 specific bugs/issues will no longer be solved. In a later stage, existing functionalities will also be adjusted to no longer have to cope with the restrictions of IE11.

Synopsis

Key Announcements

A new look and feel for ContextHub and DashHub

RN1i.png

We’ve been busy improving the look and feel of our software in order to provide an optimal experience across all TrendMiner hubs.

TrendHub NextGen (currently in beta), ContextHub and DashHub now provide a uniform experience with a user interface that helps you focus even more on your daily analysis. Guiding our users, helping them succeed in their tasks is what we aim for, and is something that we are actively trying to improve with each release.

What’s included?

  • A clear, uniform layout with more efficient use of screen estate.
  • Resizable and collapsible navigation panels.
  • Introduction of the view bar, which always shows you what view you’re looking at, whether you have unsaved changes or not, and gives you access to the view’s action menu.
  • User guiding call-to-action sections to help you succeed and get started in a quicker fashion.
  • Countless of user interface improvements that shape a modern application.

Support for connecting to multiple OSIsoft PI Event Frame databases

Administrators could already define multiple TrendMiner data sources connecting to different OSIsoft asset frameworks. Starting from this release, it is also possible to define multiple "PI asset framework" data sources with, next to asset capabilities, also context capabilities to sync the additional OSIsoft Event Frame databases as well.

Important notes:

  • The Event Frame synchronization settings have moved to ConfigHub. After the upgrade, your current Event Frame Settings are migrated to a data source over there with context capabilities containing your current settings. Please check if all these settings are migrated correctly and the data source is available. If there are any issues, please contact support before adding the data source manually.
  • It is not supported to configure multiple data sources to the same EF database. This will result into duplicate context items in TrendMiner

Application Enhancements

Improved tag-search performance

Our tag-search procedures have been changed in order to improve the performance for our customers with a high number of tags. When searching for a tag via the new procedures:

  • The query requires a minimum length of 3 characters.
  • Returns the first 200 results.
  • Results are sorted on name (ascending).

Suggestions for tags/views when visualizing context items

In TrendHub Next Generation (currently in beta), we’ve made improvements to the “visualize” option for context items. By adding a list of suggested tags and views to the visualize panel, based on the user’s most recent activity (up to 10 each), it is now much easier for users to find back relevant tags to include in the visualization. Selecting a recently used tag/attribute will add that tag to the list of selected tags to visualize, selecting a recently used view will select all tags from that view.

TrendMiner version in user drop-down

In TrendHub Next Generation, ContextHub and DashHub, you can now, as a user, consult the version of TrendMiner which is installed. This can simply be done by clicking on your user name which is located in the top right corner in any of these hubs.

Admin: Improved insights in the integration-status of OSIsoft PI AF data sources

In order to increase the agency of TrendMiner administrators, specifically in case of integration issues with ContextHub data sources (Asset Frameworks & Event Frames), we have added a dedicated “Diagnostics” page in the “Data” section of ConfigHub.

The “Diagnostics” page is accessible through the “Data” section in ConfigHub, and breaks down synchronization diagnostics into the following sections & sub-sections:

  • Event Frame Sync
    • Live Sync
    • Excessive Interval Sync
    • Historical Sync
    • Failed Context Items
