We are using the cognite core data model and we extracted historian data which has been created as a bunch of time series. Now we have one asset that we would like to link these time series to. How do we do this?Please help, thanks.

Hi everyone! When importing data for a specific TAG, I notice multiple connecting lines or links between TAGs across the same P&ID. What steps can I take to minimize or reduce these connections?”

Is there a plan to support enumeration (or any way to restrict value of string properties) in the future?Enumerations are described here: https://graphql.org/learn/schema/, but seems like its currently not supported: 

We are now planning to integrate a large amount of historical data. The context about historical data and our data organization is in this topic:We create an interface WellState, which contains 2 properties: WellId and Archived, in order to propagate the Archived flag to every object in our data models.After integrated large historical data in our development env, we found that DataFetchingException always occurred in Daily(550K lines) and Operation(2M lines) in using GraphQL. And if using cdf_nodes to load Daily and Operation, the transformation will be blocked util that your session is closed.Info: Daily has many relationships and Operation has only a relationship with Daily. But We have also other 3 objects like Operation(big dataset and a relationship with Daily), they can work well. GraphQL:query MyQuery { listOperation { edges { node { externalId space } } } listDaily { edges { node { externalId space } } }}the result is alwa

I am facing issue of jupyter notebook getting crashed frequently. It is observed for larger data and surprisingly ML model training on smallest data chunks as well.Sharing the image for reference.  

Hello,We are querying the view WfAlarms (structure as given below) which has direct reference to alarmCode. When we are querying it for say 3+ months, we get the CogniteApiError, but works fine when it is 1month. This error is seen in our application deployed in production. We expect almost 2 million of records in this view. Can you help to understand what can be done to fix this issue ? Any configuration that needs to be changed. Let me know if you need any other details.1.

As of January 1st, 2026, the Rule-Based Coloring feature in Industrial Canvas will transition from public beta to private beta. The change will not affect existing users who have previously enabled and are using the feature on a daily basis. The feature will be unavailable for new and existing users who are not in the private beta program.No action is needed. If you have any questions or concerns, please reach out.Thank you,Andreea. 

Can’t deselect tag when only 1 tag is selected. Pressing “Clear” will reset all filters and take me out of the menu.  Markus PettersenAker BP - Data Platform Architect

The “Ask a Question” feature inside the Canvas is very helpful—it allows users to quickly access specific documents and find information easily.However, I noticed that this feature is not available in the Industrial Tool – Search option or under the Data Management – Data Explorer tab. It would be very useful to have this functionality directly within the Data Explorer, as it would make the process more efficient and user-friendly without needing to switch to Canvas.What are your thoughts on this?Is it possible to consider adding this feature to Data Explorer in the future?

Hi team,I am looking for a way to trace data lineage in CDF. For example, if we have a table in RAW that feeds another table through a Transformation, is there a straightforward way to see where that data is being used downstream?Basically, I want to understand how to track which tables, transformations, or data products depend on a particular RAW table. Any native feature or recommended approach for this in CDF?Thanks!

Hello,I’m using a Cognite MQTT Extractor.I wonder if it is possible to publish with this client to the same broker I am subscribed to.Furthermore, I would like to know if it is possible to develop callbacks in a similar way to Python clients, for example : https://pypi.org/project/paho-mqtt/#callbacks Regards,Pierre

Hi, I’m using the hosted REST extractor to populate a data model from an MES system. One of the API calls I need to make uses a URL parameter “id” to get data for production jobs by their id like: GET /scheduling/v1/jobs/{id}/operations . The production jobs are already in my data model and each has a unique id value.Is there a way to query the job ids from my data model within the hosted REST extractor so I can make a separate REST call for each job id? I was thinking the pagination feature would be the best approach, but I’m not sure how to query my data model from there to get a list of job ids to iterate through.Any insight is appreciated. Thanks!

 Below I have attached three screeshots where I query same data in same time range. I have used Queries in first screenshot, and it corresponds to original data inspected in Charts, i.e. there is no data before 4:01. This is very basic query using external id. However in many cases we need custome query where we use parametrised syntax. I have used a very basic syntax in the second screenshot that only use external id to query same timeseries as first screenshot. But the result is clearly different, there are datapoints created where there should be no data. Inspecting the datapoints in query, I see real data points with some values are created in no data area! Disabling aggregate resolve problem of creating non exiting data in third screenshot but then it query all datapoints and saturates in 2 seconds (reach max datapoints that grafana can show). So I need aggregated data and I have tried aggregate inside the syntax and same problem in scheenshot2 persists in this case. Any idea how

Hi Cognite Community,We will be performing scheduled upgrade today from 4:00 PM to 8:00 PM CEST. Our platform will be temporarily unavailable. We appreciate your patience.

Hi Canvas Team -  Do we have the ability to make a public canvas that has the ability for the owners to lock & unlock it (making it essentially read only)?  Examples of this will include the ability to save a work package, turnaround package, reliability root-cause analysis, etx that others can see in the future however they can’t edit. The owners (people specifically shared) have the ability to unlock and edit it.   Other scenarios are a read-only version of the canvas for other people that are not the owner.

Workflow to Connect Power BI to FT DataMosaixI am currently experiencing issues connecting Power BI to FT DataMosaix for the project ai200prodtesting-44-datamosaix. I would like to highlight that for the essc-sandbox-44 project, the connection works as expected, as shown in the evidence below.Below is the step-by-step procedure I followed to connect to the ai200prodtesting-44 project:Steps:1. Select Get Data > Cognite Data Fusion (REST API) connector.2. Set up CDF Project and CDF Organization.3. Choose Sign in as a different user.4. Enter user email address.5. Enter user password.6. Click Connect.7. Review the error message: Unable to connect. the message with the error "Unable to connect" attached.

Instead of storing String data as timeseries, we would like to store data in Staging and then transform to Events with addition metadata.Can the existing OPCUA extractor support that?

Sideways scrolling is really cumbersome, why have you made the UI significantly worse? 

Hi,I want to set up monitoring of timeseries wrt reservoir levels. Yesterday I also set up a dummy monitoring, simply to test the functionality. I set the monitoring to alert when timeseries is over 1462.88 meters, which was crossed yesterday evening, but no alarms were triggered.Please see screenshot of my setup below, does this seem right? BR,Jørgen Aarstad
