During the calculation of adding two time series, if one of them has no value, will the calculated timesseries give me some interpolated value?In the example below, the ‘Error Intern’ series has a value of 2252, but in ‘Total Down Time’ I’m getting 2756.64, which is incorrect—it should also be 2252.Why is it still giving me a linear interpolation value even though I selected the interpolation type as ‘step’?  

Why are we making this change?The CDF CLI was originally designed to streamline application development on top of CDF, specifically focusing on Data Modeling workflows and the generation of type-safe SDKs.However, to ensure we are delivering the highest value to our developer ecosystem, we are refining our product strategy and priorities. The CDF CLI (beta) has not been under active development for some time, and maintaining it to our quality standards no longer aligns with our current roadmap. By discontinuing this tool, we can refocus our resources on the core tools and SDKs that best support your integration with Cognite Data Fusion.If your current CI/CD pipelines or local development environments rely on installing this package, you must take action before February 18th, 2026 to avoid build failures.Timeline of Events February 18th, 2026: The @cognite/cdf-cli package will be unpublished from NPM. You will no longer be able to install it via npm install or yarn add. What do you need

I’m using the CogniteSDK. I have seen the following behavior several times: assets = client.assets.list()the variable assets can contain deleted assets if they have been recetly deleted. If I find the external_ids of these assets, the client.assets.retrieve_multiple(external_ids=deleted_xids) correcly do not return the assets. The assets cannot be found in fusion either. I suspect that client.assets.list() is using cached values. This also applies with arguments, f.ex LabelFilter. I have seen the issue many times, but now it really got painfull, so therefore I’m writing here. It returns assets that were deleted several days ago.  What to do? 

Hello, Although “unitless” is an alias of the dimensionless:unitless unit, try_get_unit(“unitless”) returns null.ref: https://github.com/cognitedata/units-catalog/blob/main/versions/v1/units.json#L1699 Could you please have a look? Thanks!

There are some signals that in the names or the description have the words: alarm, warning, or fault. E.G. There is this alarm signal, (in red ) that I’m comparing with one of the vibration signals.  And the alarm seems to be on when the vibrations are close to 0 and the Compressor is off. I’m plotting the label as a combination of the name and the description, but the externalId of the alarm is: pi:160268In most cases that alarm is on when the compressor is off, except in this case, Where I do not see any problem with the vibration signal: There are these other two alarms, from the plots: one is on when the compressor is off and the other one when it is starting up. But I do not see any strange behavior in the signal when they occur. Besides the alarms, I’ve also looked into some of the fault signals but those seem to be on for very long times: Is there another way to use the alarm and fault signals to label anomalies or failures? I don’t know if using the vibration signals is the bes

Can we visualize Visio files with.vsd extension in Industrial canvas?

What capabilities are required to run a transformation using client credentials? I have a client_id and client_secret that when I add to the transformation and hit ‘Test credentials’ it says ‘Credentials verified’. However when I run with client credentials I get an error: Transformation job could not be created. Error code: 403 API error: Invalid source/destination credentials: Token did not provide access to project kuraray-america. Request ID: eb5136ee-594d-971f-b27a-7be0d1a60b15these credentials are a part of a group that that has read and write capabilities to:transformations sessions datamodelinstances (that is what this particular trasformation is creating)Additionally I am part of the same groups as this client_id, and I am able to run the transformation using ‘run as current user’ successfully

Hi everyone,I have a question: Can we use data from Data Models in Canvas?Is there any way to visualize that data available in Data models into Canvas?In our case, we are using Cognite Charts with time series data coming directly from machines (e.g., good parts, bad parts). However, the time series does not include product or batch information, which we do have in our Data Model.Is there any possibility to link both sets of information together for analysis?My initial thought is: if I can bring the required data from Data Models into Canvas and then create charts there, it would make the analysis much easier.But I’m not sure if this is possible—or if there’s another approach you would recommend.Any suggestions or best practices would be greatly appreciated!

Hi, I have defined a Data Model with a Source View having a DirectRelation to a Target View as a simplified version below, which Pygen created an SDK successfully.  But when I added a ReverseDirectRelationApply to the Target View, Pygen returned the captioned error.  Please help.source_container = ContainerApply(       space =”myspace”,       external_id=”sourceContainer”,       properties={            “sourceName”: ContainerProperty(type=Text, name=”sourceName”),            “target”: ContainerProperty(type=DirectRelation(is_list=False, container=ContainerId(space=”myspace”, external_id=”targetcontainer”) } target_container = ContainerApply(       space =”myspace”,       external_id=”targetContainer”,       properties={            “targetName”: ContainerProperty(type=Text, name=”targetName”)} source_view = ViewApply(     space = “myspace”,     external_id = “souceView”,     version = “1.0”,     properties = {           “sourceName”: MappedPropertyApply(container=ContainerId(“myspace”,

Is there a way to annotate 3D models towards instances from a data model. In the API documentation I only see linking to assets as an option.  

With the Java-SDK, I don’t see an option to supply the client-name during initialization of the client.  https://statics.teams.cdn.office.net/evergreen-assets/safelinks/2/atp-safelinks.htmlIs there anyway we can do that? We need the client-name for logging purpose. 

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,We are looking into contextualizing our data models with 3D info, based on the relevant concepts/types from the Cognite Core Model. However, we ran into a limitation that as far as we can see severely limits the usability of the functionality as is.The CogniteCADNode has a direct relation to a Cognite3DObject, that can be made up of multiple CogniteCADNodes, reflecting that an asset may correspond to multiple nodes in the 3D model. That makes sense. However since the link from CogniteCADNode to Cognite3DObject is a single direct relation, the current model does not allow a CogniteCADNode to be part of more than one Cognite3DObject, which typically is meant to correspond to an asset. That is unfortunately in direct contrast to reality. One CAD node belonging to many different assets/objects is not an edge case, rather, it is the norm, at least for Aker Solutions.Have we correctly understood the current functionality? If so, are there any plans to amend this limitation? Do you have a

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: 

Hi Everyone,Previously, I was able to bring my Cognite chart into Canvas, and it displayed correctly without showing the calculation area at the bottom. However, starting today, I can still add the chart to Canvas, but nothing appears—it’s completely blank. We tested this across multiple profiles, and the issue occurs for all of them. Is anyone else experiencing this problem? Could the Cognite team help us resolve it?Thanks in advance!

Hi Everyone,Is there a way to create an alert directly on a calculated series in Cognite Charts?From what I’ve found, to create an alert for a calculation, I first need to schedule the calculation and then run the alert on that scheduled result. However, scheduling doesn’t seem to work well in my case.For example, if I receive machine data every hour, I also need to schedule the calculation every hour. Sometime scheduling stops by itself. It would be much easier if we could create alerts directly on the calculation without scheduling.Secondly, I’m not finding clear documentation or videos on how to schedule calculations properly and what best practices to follow. If anyone has experience with this or can share guidance, please let me know.Thanks!   

Hello, When I’m connecting to the virtual machine Ubuntu, I’m facing a pop-up “connection failed”. It seems that my internet connection is not set up, do you have any idea to do so ? I’m not able to do rest of the training without connection. Thanks 

Hi everyone,As we prepare for the General Availability release of Records in CDF on December 2nd, 2025, we're implementing important changes based on learnings from the Private Beta program.Timeline: These changes will be rolled out progressively between today and December 2nd, 2025. We'll update this post as specific changes go live.What's changing:Record-specific containers We are introducing a new type of container dedicated to records, which has higher limits for number of properties, and will allow evolution of the records specific container as more features are made available in records. This container is defined by the usedFor field set to "record". It will be possible to ingest records only into containers with usedFor set to "record" Any records already ingested into non-record containers will remain queryable, but new ingestion attempts to these containers will fail This separation enables better schema management, clearer data organization, and simpler logic for clients q

Hi Everyone!I need to manage streamlit applications (read / update files) using the Cognite SDK or with the API.I was able to publish streamlit applications using the cognite toolkit, but I also need to read them.Tried searching the api-docs and cognite-sdk docs with no luck. Thank you!

In the process of initializing a new CDF tenant for one of our customers I am getting the following error when adding Assets Read/Write capabilities: 1 invalid capabilitie(s) are present: {"assetsAcl":{"actions":["READ","WRITE"],"scope":{"all":{}}}} (invalid capability - write access to the legacy Assets API is restricted) | code: 400 | Are core assets now restricted?

Hi Team, we have data in format like list of externalIds and space as key and value.  Like list of Json object in data model. something like [{externalId:well,space:slb},{externalId:well1,space:slb2}]So can we keep a field in model like violatedEntities: [JsonObject]Is it possible to parse all the externalIds and store it like this?Thank you.

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
