How do you set and see the interpolation rules for your dataset in CDF? 

Hello,We are currently facing issues when trying to connect CDF to Power BI. We have already granted all the necessary permissions according to the official documentation, but we are encountering the following problems: Connection via Username and Password: Although Power BI lists the objects successfully, we are unable to visualize their content. It results in the following error:   Connection via API Key: The authentication screen in Power BI prompts us to enter the API key. However, when we provide the key, it is marked as invalid. Here we can see the CDF objects but not the data itself.   Is there a step-by-step guide to correctly configure and use the API key for authenticating in Power BI? Could you provide some clarification on whether there are any additional organizational settings that could be causing these errors during authentication?Any insights or guidance on resolving this issue would be greatly appreciated.

Our project has used the standard logging module for displaying information, warnings and errors in the Cognite Function log interface. This has worked on the Google tenant of our CDF (despite the warning in the docs), but no logs are shown in our new Azure tenant.Do we need to update our code to a different module, or write our own logger class? Or will the logging module be compatible?

Hello,I am using a Litmus Edge system and would like to ingest simulated data into Cognite Time Series by leveraging the Litmus Cognite Connector.Additional Details: We also tried manually creating a time series in Cognite Data Fusion (CDF) with the same name as in Litmus Edge, but we are still unable to successfully ingest data into the corresponding time series.Getting below error in Litmus Edge151. 2024-12-12T06:33:25.360349408Z {"error":{"code":401,"message":"Unauthorized"}}152. 2024-12-12T06:33:25.36049081Z publish message: request is unsuccessful: 401 Unauthorized 

Hi,Apparently I lost the account in the authenticator app while not changing phones. How do I get this back? Due to this I am also not able to access the sharepoint site to exchange files with Cognite.Regards,Ramon

Hello, we have set up an extraction pipeline with notification alerts. One of the contacts defined is an email address for a Microsoft Teams channel: <xxx.yyy.onmicrosoft.com@emea.teams.ms>, but we have not received notifications to this channel the last couple of days. Are this kind of addresses blocked in some way? We know the alerts have been triggered becuase we have other contacts defined with different email addresses and they receive the alert.

Hi Everyone,I need to create query like it is creating on cognite UI’s  like   { "listEntity": { "with": { "0": { "limit": 50, "nodes": { "filter": { "and": [ { "matchAll": {} }, { "hasData": [ { "type": "view", "space": "slb-pdm-dm-governed", "externalId": "Entity", "version": "1_7" } ] }, { "or": [ { "and": [ { "nested": { "scope": [ "slb-pdm-dm-governed", "Entity/1_7", "parent" ],

Hello Community,The Records and Streams APIs are now available for early adoption, with an expected announcement of Beta software maturity level in January 2025. Intended use cases for Records are the storage of high volumes of structured data such as Logs (i.e. Alarms and Events, Manufacturing Logs and Well Logs), and Historic Data.  The API is designed to handle hundreds of billions records per year, from various source systems.  Use cases that currently store historic data as Nodes in the industrial knowledge graph are excellent candidates for the use of the new API.Early adoption means Cognite provides you access to pre-production APIs (and later SDKs) in return for engagement and feedback during the product development process.  By default, the APIs are not enabled in every customer project.Early adoption intended to provide those customers who are interested in utilising the API functionality in their future plans, the ability to gain an understanding of the product concepts, pro

Hi everyone, one question:Does DB Extractor run on Windows 11?So far it hasn't worked for me

These overlap, this causes problems. The ”Open in canvas” box overlaps and blocks some of the annotations. 

Hello everyone in the community, question:I have a lot of files and I want to organize them by type and take advantage of the functionality of creating categories.I created the manual category for the photo file as metadata, but the "folder" or category is not visible, what am I missing?help   

@Tanmay Deshpande and @Tom Jonsthovel , posting your question here to make it easier to engage the developer team for support. We have successfully created the ILA group and can call the API, however we currently get stuck on ingesting logs (400 - bad request). Please see our steps below.  It would be great if you could advise on how to properly ingest logs and share a Jupyter notebook with some examples. Also, would be great to understand the link between the ingested log and the container. Eg, do we need to add a 'log' property to the container definition?Created a data model. Ingest a log into the container with externalId "Pump" and link to "Pump" instance with externalId "66470bf0-5c07-4a39-8878-0adf4dc7f448"Get 400 on return. 

Hi guys, I’m facing an issue while trying to populate a data model and create a hierarchy of assets. Despite following the steps outlined in the microlearning materials step-by-step, I am unable to visualize the asset hierarchy in the data model.It appears that the hierarchy is not being created, even though the process runs without errors.For reference, I have attached the transformation I used to populate the data model.I created the space "DnI-Assets” and the target was the Cognite Core model and Cognite Assets.I can see those assets within the data model > Cognite Core > Cognite Assets instances. But not the Hierarchy itself.  I'd like to see the assets hierarchy and the graph views. Any idea how to solve this? Best regards,Daniel

What is the limitation of objects you can add to a Canvas? I started seeing performance issues when I had ~10 documents in a Canvas. Is this expected behavior? What is the recommendation for Canvas size?

Hello! What is the difference between a “line” and a “connection” on Canvas? 

Hi,I tried to look for a solution, but cannot find one that is related to Sequence extraction using SDK.May I know do we have an option to filter the sequence data by the Timestamp or date? As far as I know, we can only filter the sequence data by id, externalId, start row index and end row index. I need to retrieve data from Sequence based on the Date Range. Anyone knows how to do that? Thanks. Regards,Sharizan

Hi,I am trying to set the is-step parameter of a timeseries a tag that I am reading from a ThingWorx Kepware Server OPC UA server to true.I am using the config.example.yml that comes with the OPC UA Extractor installation and the following document as references: https://docs.cognite.com/pt/cdf/integration/guides/extraction/configuration/opcua#-custom-numeric-typesThe source tag has a Long data type in the OPC Server (no decimal digits). It is increasing from 0 to 100 in a increment of 1 updating every 5 seconds.I created a very simple yml (attached) containing only the tag that I want to read. It is a working file, meaning that I can see data flowing to the cloud, but the step property does not change to true. What could be missing?Thanks.

Does Cognite AI search multiple documents when you ask a question, or does it stop as soon as it finds an answer?When I selected multiple documents in Canvas and asked AI a question about them, it seemed to only give me answers from one of the documents. 

I have changed my mobile phone as last one is lost. Trying to set up microsoft authenticator in order to use cognite tool but not able to set authenticator. Please help on this.

Hi Everyone,I’m reaching out to the community to gather valuable feedback and insights on Cognite Data Fusion (CDF), specifically its Canvas + Charts features as applied to Root Cause Analysis (RCA).How are these tools impacting the RCA process? In your experience, how have the quality, dependability, and response time of RCA processes improved since implementing CDF? What kind of improvements have you observed in identifying root causes, especially in terms of speed and accuracy? With the inclusion of Generative AI (GenAI) within CDF, how has AI-driven data exploration changed your RCA workflows?I’d greatly appreciate hearing about how the combination of Canvas, Charts, and GenAI is transforming the way you approach RCA, and any real-world examples or challenges you’ve faced.Looking forward to your insights!RegardsMuhammad Waqas 

A chart in Canvas should update if it is changed in Charts. For example, I added a Chart to my Canvas. Then I added another timeseries to my Chart. But in Canvas, the chart didn’t update with the new timeseries. 

I am trying to update column value in view using upsert method, but it's not working and giving 400 error code.  adding screenshot of upsert api, as its not matching with the input structure provided in document.

Hi there,Before I begin, some terminology to make sure we are on the same page.CDF tenant = CDF project (these have been used interchangeably over time, not sure which is applicable at the moment, I will be referring to it as tenant)CDF cluster = The cloud cluster where the CDF tenants/projects/instances are hostedNow, let’s begin.At Aker BP we have been migrating over to a dedicated CDF cluster on Azure and we have been experiencing some pain points with regards to the compute resources being shared for all tenants on the cluster. Previously our CDF tenants were hosted on GCP on a cluster shared with other companies, this cluster is scaled to handle multiple customers and so the base scaling of the compute resources is much higher than it would be on a dedicated cluster, and as such these problems are less likely to be encountered, not impossible just not as likely. The problem we have seen is that if we from our dev tenant overload the API then the API becomes unavailable for all our

Hi everyone,I’m exploring the possibility of using the Shap library for model interpretability in Cognite Jupyter Notebooks, but I understand that Pyodide has limitations with packages requiring native libraries. According to the Pyodide FAQ, such packages may not be supported.Would it still be feasible to include Shap, or is this limitation a blocker? If it’s not possible, are there any recommended workarounds, such as using a different package?Thanks for any guidance or insights!Best regards,

Hi! I’m working on a Equinor project where we’re using the Cognite GraphQL. When using the list-query with the sort property it returns more items in the result than it does when there sort property is not included. The only difference in the query is the sort-property. Our dataset has more than 1000 items, so we’re fetching paginated data. I’ve been told by a team member from Cognite that this is a known bug, however, we would very much like to know what the timeline is for fixing it? We need the sort functionality so if it is not being prioritised we will need to implement a workaround. But would of course prefer not to have to do that. Thanks!
