TrendMiner 2022.R1.0

29th of April 2022

The 2022.R1.0 release contains the following new functionality and improvements:

TrendMiner starts the year on a high note with the release of multiple major improvements in the areas of product leadership, product experience and product security

TrendHub Next Generation

We are proud to announce the full launch of the next-generation (advanced) trend client & industrial analytics Hub for time series sensor data. Based on your extensive feedback, we’ve drastically improved the user experience such that even more than today, TrendHub will empower operators, engineers and other domain experts to visualize historical and real-time process data and dive into the data to analyse, diagnose & predict production or equipment issues, based on the well-known and powerful capabilities of the TrendMiner analytics engine. 

What does this mean for our users?  

  1. Improved and even more user-friendly trend viewer, including simplified grouping & auto-scaling of multiple tags, scrolling & panning of axis, more detailed scatterplots colored by time, etc. which gives users the full flexibility and agility to visually explore sensor data. 
    • Initial feedback from TrendHub Beta has already been taken into account. Check the synopsis section below to learn about the additional improvements.  
  2. Central role for views in your analyses with simplified view saving, including live views and active filters + direct access to descriptive analytics (period statistics & comparison). 
  3. Streamlined search-experience including multiple calculations on search results, saved with the search definition for easy replication on new time periods or similar assets. 
  4. Improved implementation of the Recommender Engine as Diagnose to facilitate global Root Cause Analysis with configurable upstream time shift. 
  5. New implementation of Influence Factors as Prediction Tags to facilitate soft-sensor creation, next to a revamped Predictive Mode to explore future evolution of sensor data. 

To accommodate the change in user experience, we are also launching an improved in-app learning & support experience with a brand new getting-started guide which allows users to access in-app tours at their own pace, 1-click access to the in-app help-center & online e-learning courses as well as the well-known options to reach out to the TrendMiner team. 

Secure by Default 

Security is something that can have severe implications if something goes wrong. With this release we are making a significant step forward as we have adopted a Secure by Default and Secure By Design approach for our platform. Under the hood, this means we have replaced our security backbone as a starting point. All future releases of TrendMiner will add additional improvements to ensure that any installation of TrendMiner is secure by default, enforcing security best practices without needing additional configuration.   

What does this mean for our users?  

  • If you are using TrendMiner for user management, you will notice stricter password policies and expiration rules. These are based on best practices and ensure your users passwords are more secure.  
  • Extended support for integrating with your existing identity providers, such as supporting a combination of local user management with multiple IdPs via SAML (e.g., Azure AD, Okta), and/or multiple LDAP providers, as well as support for using SAML groups in defining data access rules which unlocks the option to pre-configure access permissions for new users. 
  • We will enable SSL/TLS by default (you access TrendMiner in your web browser using a secure “https://" URL), so any data transmitted to and from TrendMiner will be encrypted using up-to-date and secure encryption methods.  

A seamless integrated platform experience 

The TrendMiner analytics platform consists of 3 Hubs each with their own strengths (TrendHub for sensor timeseries visualization & analysis; ContextHub for knowledge sharing, process event visualization & analysis; DashHub for bringing your views and analysis results together for personal follow-up or sharing with your co-workers), and with this release we are further improving the  integration to foster an even stronger analytics experience from spotting sub-optimal operations / energy-usage / … in DashHub, to visualizing related anomalies / defects / … in ContextHub, to deep-diving into the related sensor data for root-cause analysis in TrendHub. 

What does this mean for our users?  

  1. A Unified Monitoring Center, which brings together the monitor configuration and inbox and provides easier access to historical results and related searches, accessible from all Hubs. 
  2. All TrendHub visualizations are now available DashHub, including stacked trends, histograms and scatterplots as well as improved (regular) trend visualization.   
  3. All ContextHub visualizations are now available DashHub, including table & Gantt displays, so that you can build even better, more extensive and more complete dashboards. 
  4. Easily compare the process events from ContextHub based on sensor timeseries data by visualizing multiple context items at once in TrendHub, eg. to easily compare batch run data. 
  5. Get suggestions for which component to use when creating a context item, depending on the view you have open or which tags, attributes or assets you recently used. 

Additional New features 

TrendHub 

  • Multiple calculations on search results: add multiple calculations to the search results and save them as part of the search definition for easy replication on other timeframes or assets. 
  • Start and End value calculation available for digital tags in the statistics and compare table.  
  • Duplicate states in the digital state mapping table of OSIsoft PI are now supported. 

ContextHub 

  • Sorting on all context item fields in the context view table. 
  • Browse through asset trees performance gains of up to 2500% when browsing large asset hierarchies. 
  • Customers with a lot of context data (batch, maintenance, quality…) will experience speed gains of up to 400% when querying context data, so their table and Gantt views will remain snappy and responsive. 
  • Repairing and resyncing 3rd party integrated context data (e.g. OSIsoft Event Frames).  
  • Support for secondary referenced elements for context items originating from OSIsoft Event Frames.  

DashHub 

  • External content tile: support embedding images, videos or content from external tools/data such as PowerBI, Tableau, PI Vision, P&IDs, 3D CAD models… into a dashboard. 
  • The Context tile will now reflect the correct number of items in a view when asset permissions are applied. 

Monitoring&Alerting 

  • Access to the most recent 50 monitoring results, irrespective of read/unread status + quick access to your saved search to retrieve all results. 
  • Unsubscribe from monitoring email notifications: Now TM users can unsubscribe from the email notifications using a link in the email. The users can only unsubscribe the email address linked to their TM account. 

ConfigHub 

  • TrendMiner API clients: client & secret generation for external API usage. 
  • Pre-configure access permissions for new users by defining data access rules based on SAML (eg. Azure AD, Okta) or LDAP groups rather than individual users. 

Bug fixes 

  • Support for self-signed certificates is added on triggering monitoring webhooks. 
  • Fixed an issue where modifications to or deletions of digital states in the OSIsoft PI digital state mapping table resulted in indexing errors. Digital states are currently not resynced. Please reach out to support in case digital states have been modified in OSIsoft PI.  

Known limitations  

  • The cross asset value based search is not available in TrendHub Next Generation.  
  • The advanced similarity search is not available in TrendHub Next generation. Monitors, however, which rely on such a search are migrated and will keep on working.  
  • Search results are currently not indicated on the context chart.  
  • 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. 
  • 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 this release 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.  
  • We recommend to upgrade your underlying disks from HDD, 125MB/s to SSD, 250MB/s to guarantee user performance. Faster disks will also significantly boost the migration towards TrendHub Next Gen, allowing less downtime during upgrade to this release. 

* 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 

TrendHub Next Generation 

We are proud to announce the full launch of the next-generation TrendHub (advanced) trend viewer & industrial analytics Hub for timeseries sensor data. Based on your extensive feedback, we’ve drastically improved the user experience such that even more than today, TrendHub will empower operators, engineers and other domain experts. 

With TrendHub Next Generation we implemented more than 600 feature ideas we received from our customers. Seeing the many improvements, it is impossible to list them all. You will discover small improvements daily!

To kickstart your TrendHub Next Generation journey, there are multiple resources at your disposal:

  • Check the sections below to get an overview of the main highlights. 
  • Follow our new 20-minute eLearning course to get introduced to TrendMiner Next Generation (ideal for users transitioning to TrendHub Next generation). 
  • Follow our brand new TrendHub Basic eLearning for more details (ideal for new and recent TrendMiner users). 
  • Visit the brand new getting-started guide where you can follow in-app tours on request. 

Improved trend viewer 

We drastically improved our trend viewer to make it even more user-friendly, giving users the full flexibility and agility to visually explore sensor data. Some examples include simplified grouping & auto-scaling of multiple tags, scrolling & panning of axis, more detailed scatterplots colored by time, etc. 

Views play a central role in Trendhub Next Generation.  The current view is always indicated at the top of your screen and view actions are easily accessible.  The complete configuration of your view will be stored when saving a view, including the visualization mode, live button, active filters, fingerprints and chart settings.  

RN1.pngRN2.png

Descriptive statistics for the base period (Statistics) and all other layers (Compare layers) are easily accessible and can be displayed together with time series data.

RN3.pngRN4.png

TrendHub Next Generation improvements based on early user feedback

With the Beta version of TrendHub Next Generation, a lot of the trend viewer improvements were already available. Initial feedback has already been taken into account and the following additional improvements can be observed:

  • Fixed headers: Headers of the compare layer and statistics table are now sticky and will always be visible when scrolling through the table.
  • The shift buttons have been improved to easily apply a sequence of shifts.
    • The export functionality received multiple improvements.
    • The chart visual export contains more details, now including component descriptions, units of measurement, and shift values. Also, the layer name is included in the export.RN5.png
    • It is now possible to export a single scatter plot or even a histogram. Just select the specific histogram or single scatter plot before starting a chart (visual) export.
  • A colored points option has been added to the scatter plot configurations. Once the option is enabled, the points on the scatter plot will have a color grade from oldest (in blue) to newest (in orange) values.
  • The interpolation type option for IP21 tags is added.
  • Added filters and their states (enabled/ disabled) are now saveable as part of the view.
  • In predictive mode you can now zoom in and out using your mouse wheel without disabling predictive mode. Note: Predictive mode stays enabled if future timestamps are visualized.
  • A scatter plot can now be saved on the desired level of interest in your view.
  • Off-the-chart values are now also displayed on data scooters.
  • Panning option has been added to all axes in TrendHub (focus chart and context chart).
    • Panning is an option to move the charts axes without the need of using the time pickers or shift buttons.
    • Depending on the state of the lock button you can either move your current period (locked state) or increase the current period (open state).
    • The Y values can also be increased.
  • The context chart area has received a major update:
    • The "Double slider" has been replaced by predefined periods, drastically simplifying the search scope selection.
    • A custom context chart period can also be set instead of the predefined periods using the custom option.
    • Next to the period option there is an option to use the visualized period of focus chart as context period.

Streamlined search experience

Both the workflow of performing searches and the user experience when working with the search results have been improved.
The workflow of the searches has been unified, to provide the same experience, whether you start a new search or start from a saved search. There are now only 2 main screens:

  • The set search setup screen to specify the search conditions.
  • The search detail screen providing a summarized overview of the search conditions.

When opening a saved search, you are immediately directed to the search detail screen, where you can choose to perform the search or edit the conditions. The search detail screen is a static representation of the currently active search. Any changes to the chart (which is important for the similarity search and area search), are only considered when explicitly editing the search.

At any time, the period for which the search will be performed (selected via the context chart), will be indicated in the search overview as well.RN7.pngRN8.png

Similar to the views, modifications to the conditions will be indicated as "unsaved changes" and the user can decide to save the search as a new search or to overwrite the current search. This allows users to easily apply an analysis on similar assets.

RN9.png

Multiple calculations

Being able to perform and export multiple calculations on top of search results has probably been the most requested feature. With the introduction of TrendHub Next Generation, this feature is now available and can be found as an action on the search detail pane.

Up until 30 calculations can be added at once. In the search result list, one specific calculation can be selected which will be visualized on top of the results and will be used when sorting on calculations.
As a bonus, the calculation definitions will be saved as part of the view, once again simplifying the reproduction of your analysis. Once calculation definitions are available, the calculations will be executed when performing the search.

RN10.pngRN11.png

Result list improvements

Working with the search results is now much easier and there are multiple improvements included in this release.

The user can switch between showing the results in bins (default option) or to show them as a flat list. Click on the flattening button to display the results in a scrollable list. When scrolling down, the user can easily jump back to the top of the list by clicking on the blue arrow displayed on the list.

RN12.pngRN13.png
With the introduction of the sorting button, the user can sort ascending or descending the results of the current bin he is working on. By default, the results are displayed descending and in date bins, except for similarity search, where the results are sorted descending by score.

To switch the sorting mode of the bins (date, duration, calculation, or score), the user can select the mode in the search results menu.

RN14.pngRN15.png

Adding the results as layers is simpler and clearer than before. The user can add layers by clicking the link under the search result or set it as a base layer. When the user adds a result as layer, it will be displayed with the layer icon and indicated in a blue color. The base layer will be indicated with a “B” (base). For similarity searches, the user can now identify the search result that matches the query with the “Q” (query) icon indicated on the search result. This enables the inclusion of the query period in filters, exports, and calculations.

RN16.png

Diagnose to replace recommender engine

The Recommender Engine is now replaced by the Diagnose menu to facilitate global Root Cause Analysis. The diagnose functionality can now be found in the left-side menu as any other functionality and no longer in the top menu bar. Additional general improvements include the following:

  • A clear distinction is made between the cross-correlation analysis and the fingerprint deviation analysis for a better discovery of both functionalities.
  • All settings can be adjusted before the analysis is started and a persisted result list is shown. This allows users to visually validate candidates without losing the complete analysis. The overall flow is very similar to the search workflow.

RN17.png

As will be discussed in the following section, the influence factors functionality has been rebranded and moved to the tag builder menu, making Diagnose the go to menu for root cause analytics. The following improvements have therefore been added to the cross-correlation analysis.

  • An upstream shift detection can be specified up to 24 hours, instead of the default, fixed 1 hour.
  • The minimum and maximum time shift is shown in case multiple layers are used for the analysis.

RN18.png

Prediction Tags to replace Influence Factors

Prediction tag builder is replacing our influence factors functionality to facilitate soft-sensor creation. The predictive tags allow you to create a multi-variable, linear model to predict the value of interest from any other available data.

The creation of these tags is made more user-friendly by introducing a completely new workflow which guides you to the final model in different steps. When initiating the workflow, a dedicated chart is visualized on which the model will be visualized.

RN19.png

Next to the change in workflow, the following improvements have been implemented:

  • Listed candidates are no longer returned in bins but in one list to have a better overview of all your results without opening/closing all those bins.
  • Tag/Attribute description are now included for the listed candidates to better understand which candidate is listed.
  • The resulting model, including the complete workflow settings is now saved as a new tag builder type, i.e. prediction tags.RN20.png
  • Results are persisted when switching menus and selected candidates are persisted when changing the search scope. This enables more flexibility to evaluate different selection of tags and time shifts to be evaluated during the setup of your model.

Improved in-app learning & support experience

To accommodate the change in user experience, we are launching an improved in-app learning & support experience. All resources can now be found in the top bar, as well as the well-known options to reach out to the TrendMiner team.
The help center will take you to the TrendHub Next Generation documentation, while clicking E-Learning courses will direct you to our online learning platform.
A brand new getting-started guide is now included which allows users to access in-app tours at their own pace.RN21.png

Note: Data gathering needs to be enabled to be able to use the getting-started guide.

A seamless integrated platform experience

Unified Monitoring Center

The TrendHub Inbox and monitor configuration menu has been replaced by the monitoring center, which can now be found in the top menu bar, next to the Work Organizer.

RN22.png
The monitoring tab is accessible in all hubs. When opening the monitor tab, you will be presented with a full screen table containing all enabled monitors. The main advantages of the unified monitoring center are the following:

  • Accessible in all hubs.
  • A nicely organized table overview of only the enabled monitors, which can be sorted on Name, Type and timestamp of the last result.
  • A persisted list of the 50 most recent monitor results for each monitor. Results will always be shown in this table, even if no actions are enabled.
  • Clear indication of unseen results.
  • Click through available to the original search or fingerprint, in case the conditions of the underlying item need to be modified.

RN23.png

Monitoring email

The monitoring email that is send out whenever a new monitor result is detected has been updated. These mails contain the same information as before, with the following 2 additions:

  • An “Unsubscribe” link to remove yourself from the distribution list of this specific monitor. Unsubscribing only works for TrendMiner Users and if their e-mail address was mentioned explicitly. Unsubscribing is not possible if a group email was used.
  • Indication of the owner of the monitor.

RN24png.png

ContextHub visualizations in DashHub

In order to ensure that all ContextHub visualization modes are also supported in DashHub, the ContextHub view count tile has been renamed to ContextHub view tile. The tile now enables users to visualize context data based on a saved context view in different display modes. After selecting this type of tile in the "Create new tile" side panel and specifying the desired context view, a display mode can be chosen. There are three different display modes, each with their specific purpose:

  • Count

The display mode "count" simply displays the number of context items within a certain context view in a clear way. This could for be used, for example, to monitor event types that represent critical issues, or keep track of the amount of batches produced by a production line over a given time period.

  • Table

The "table" display mode allows you to directly embed a ContextHub table into DashHub. The table configuration (columns, sorting, etc.) is directly inherited from the corresponding context view. You can interact directly with context items in the table, as clicking on any row in the table will open the context item detail panel.

  • Gantt

Similar to the "table" display mode, the "Gantt" display mode will directly embed a ContextHub Gantt chart into DashHub. The Gantt configuration (timeframe, pinned rows, etc.) is directly inherited from the corresponding context view. You can interact directly with the context items on the chart, as clicking on any item will open the context item detail panel.

Note: Some display modes are only available if the selected view meets certain criteria. The "Gantt" display mode is only available if the selected view contains a component filter. 

RN25.png

Visualizing multiple context items at once in TrendHub

It’s now possible to easily compare and analyse timeseries data related to context items in TrendHub, thanks to the new bulk visualization option. Making a selection of context items in the context item grid in ContextHub will now give you a “visualize” option in the footer menu, which will open up TrendHub and create a layer for each context item selected. For the context items that are related to attributes, the corresponding tags will be pre-selected, but it’s possible to modify this selection at will.RN26.pngRN27.png

Component suggestions during context item creation

With component suggestions, selecting the right component to new context items during context item creation has become quicker and easier, from both ContextHub and TrendHub.

  • ContextHub

The application will keep track of recently used components during context item creation and display them as suggestions when creating additional context items. If the user has a specific view open, the list of recently used components is filtered based on the components present in the view.RN28.png

  • TrendHub

In TrendHub, suggested components for context item creation are generated based on the visible active tags in the view the user currently has open. Additionally, when the context item is created from a stacked view, or a view with only a single visible tag, the tag over which the user was hovering when choosing to create a context item will be automatically pre-selected.RN29.png

Additional new features

Improved sorting on the Context item grid

To make it easier to gather insights from context data, sorting is now supported on all columns on the context item grid, except for the component column. This includes columns for custom context fields of all types (numerical, string and dropdown). Sorting can be applied in the same way as was the case for previously sortable columns, by clicking on the column header. Repeated clicks will alternate between ascending and descending sorting.

Improved manual and automatic resynchronisation of context data

Manual resynchronisation

Users can now manually resynchronize individual context items from the options menu on the context item detail panel. This can help bring outdated context items up to date, in situations where it might have gotten desynchronized from its source system. This option is only available for context items created through the context sync.

Administrators additionally have the possibility to resynchronize multiple context items at once, by selecting one or multiple context items in a table view and clicking the “Resync” button in the footer menu.

Automatic resynchronisation

Two automated clean-up processes for context items have been implemented.

  • After an asset sync or import

Upon the successful completion of an asset synchronisation or a CSV-based asset import, an automated clean-up job will attempt to resynchronise all context items in the system without reference to a component. This is to ensure that context items that should be related to new assets imported into TrendMiner as part of the recent AF sync or import, will be updated accordingly.

  • Nightly

Every night, the system will check for context items with a duration of longer than 24 hours, for which no “end” event has been received yet. These context items will be resynchronised automatically, to ensure that they are correctly updated in case the “end” event erroneously did not reach TrendMiner. ConfigHub administrators can also manually trigger this resynchronisation process on-demand from the data source panel in case immediate resynchronization of open items belonging to a specific data source is needed.

External content tile for DashHub

A new tile has been added to DashHub to support embedding images, videos or content from external tools/data such as PowerBI, Tableau, PI Vision, P&IDs, 3D CAD models, etc. into a dashboard.

In order to give system administrators strict control over which content is allowed to be embedded, a dedicated administration screen has been added to ConfigHub. On this screen, administrators will be able to specify domains from which external content is allowed.

Note: When specifying allowed domains, the use of wildcards makes it easy to allow entire domains or subdomains.

  • The use of “*” in a URL allows any variation of the same URL, without extending the path (so “www.mydomain.com/* will allow the use of “www.mydomain.com/extension1” in an external content tile, but not “www.mydomain.com/extension1/extension2”).
  • The use of “**” in a URL allows any variation of the same URL, even with path extensions (so “www.mydomain.com/**” would allow “www.mydomain.com/extension1/extension2/...” to be used in an external content tile).

RN30.pngRN31.pngTrendMiner on Kubernetes

Kubernetes is the de-facto standard for deploying and managing large scale distributed applications, like TrendMiner.  Today, Kubernetes is supported by all major hyper scalers and lots of (large) software companies provide ecosystems and tooling around it. Kubernetes is already being used today to run Software AG cloud e.g. 

With this release, TrendMiner is now being deployed on Kubernetes.  Note that Kubernetes comes in many flavours and forms, we categorize them as:

  • Edge: small (single node or a few servers) on premises deployments.
  • Self-managed: you can run your own Kubernetes platform (open source or enterprise/commercial like OpenShift). This can be on your own hardware or on a hyper scaler .
  • Managed: You leverage Kubernetes-as-a-service from your preferred hyper scaler

With this first release, we have replaced our appliance and single node deployments to run on an Edge variant of Kubernetes

Over the coming releases, we will start expanding to Managed Kubernetes deployments 
(In a first stage our production SaaS customers, and later supporting scaled out cluster deployments on customer–owned cloud accounts).
