As owner of a canvas, the Canvas UI identifies me as expected such as in version history or in comments. When another user makes edits and comments they are not identified and show up as seen in the attached screenshot. Just in case it matters, this is a Rockwell Automation DataMosaix project. Thanks!

After creating a new calculated time series in Charts, how can I replicate the same calculation across multiple similar assets?Let’s say I calculate [ampers / Fluid rate] in one pump; I’m now interesetd on repeating the same calculation across 10 other pumps (let’s assume timeseries have the same name for all pumps, i.e.: PumpX:AMP).Am I obliged to go to SDK and code that? Shouldn’t be an easier way to do that? Thanks!  

Hi,I have a datamodel in CDF and I want to run a GraphQL query through the SDK to retrieve specific data from the model. When I try to run response = client.data_modeling.graphql.query( id = ('sp_watercourse_data_model', 'Watercourse', 'v1'), query = query )I receive the following error message:CogniteGraphQLError: [GraphQLErrorSpec(message=Could not find data model with space=sp_watercourse_data_model, externalId=Watercourse and version=v1, locations=[], extensions={'classification': 'DataFetchingException'})]However, when I list my models usingmodels = client.data_modeling.data_models.list(limit=100).to_pandas()the model is in the dataframe as expected. What causes this problem and how can I fix it? thanks

I had gotten a number of rest extractor pipe lines running the other day and then paused them. I am now trying to resume them and I am getting an Startup Error message “Missing required field session key”. I do not see a field session key referenced anywhere in the documentation on the rest extractor. Are you able to give any additional inform of where I can find this field?

I have created a function that was configured to 5G of memory and 2 CPUs to run huggingface AI model (py311). Deploying the function went fine. However, when running the function it throws this error.  RuntimeError: [enforce fail at alloc_cpu.cpp:118] err == 0. DefaultCPUAllocator: can't allocate memory: you tried to allocate 9437184 bytes. Error code 12 (Cannot allocate memory)  

Are there any documented use cases or papers on integrating MLflow with Cognite, or is it something we need to implement ourselves?For example, if we aim to seamlessly integrate the MLflow UI with Cognite to evaluate and select the top-performing models, we could leverage SQLite, which operates on the local file system (e.g., mlruns.db) and provides a built-in client, sqlite3. However, our preference is to seamlessly integrate it with Cognite.

  Within our implementation we have an existing Hosted Extractor reading data from an IoT Hub that contains multiple sites worth of data. Our Hosted Extractor Mapping Template filters for events that have a particular deviceId on it, representative of the location these events are coming from. In effort of ingesting another site-location datafeed, I wanted to extend the template with an ELSE IF condition that has the mapping rules for the other location, which are almost identical to the first except for the target datasets, which I’ve come to realize is set in the Sink section of the Extractor Configuration. The net result here is needing to create redundant Hosted Extractor configurations that change only a filter, rather than having a cascading ELSE IF ruleset that applies to the full stream. For example, this pseudo-template for our existing hosted extractor configuration for one site: if (context.messageAnnotations.`iothub-connection-device-id` == "SITE_A") { input.map(record_u

Hi,I’ve encountered a bit of issue with CDF when using Microsoft Edge. The full screen button doesn’t do anything. In Chrome and Firefox it does as expected and opens the document in full screen mode.Regards,Markus

Hi, i have set notification to alert when runs failed. However, i noticed that am still receiving email notifications wherever the extraction pipeline is successfully executed. Could you please advice. thanks  

charts Daily average of the previous dayIf anyone knows a good way to do this, please let me know.I would like to see the previous day's 24-hour values by averaging the data over the day with a mean of 0 days 24:00:00 (resampling to granularity), but due to the UTC+9:00 specification, the previous day's processing does not occur until 9:00 AM in japan.I would like to see the previous day's nightly processing volume average at 8:00 AM.The only way I can think of is to use the “shift time series” to force it forward, i would be appriciated if anyone have a better idea.. 

Hi Experts, Need your help on Cognite Python sdk.My goalGet all linked timeseries of an AssetI am using Asset class object https://cognite-sdk-python.readthedocs-hosted.com/en/latest/assets.html#cognite.client.data_classes.assets.Asset time_series function​​  ProblemIt is only giving me  the ‘Directly linked timeseries’ , not all the ‘Linked timeseries.   Means in this case I only getting 13 timeseries objects , compared to 64 linked timeseries of the Asset. Appreciate your help on adopting the correct approach Thanks and RegardsSree

I would like to know the benefitS of implementing UNS architecture in CDF. A detailed guide would be excellent to show how to implement it in the oil and gas refinery with all the prerequisites and third-party platforms along with that.

Hii Team,I'm looking solution for below problem.Currently we have build our custom model using core data model. we have timeseries available in cdf.timeseries resource. Now i want to provide timeseries reference in below view using transformation. Can anyone suggest how timeseries concept is worked in core data model using transformation. type TimeseriesProperty implements Property & CogniteTimeSeries & CogniteDescribable & CogniteSourceable  @view(version: "2_1") {  name: String  source: CogniteSourceSystem  entity: Entity  sourceId: String  sourceContext: String  sourceCreatedTime: Timestamp  sourceUpdatedTime: Timestamp  sourceCreatedUser: String  sourceUpdatedUser: String  isStep: Boolean!  type: CogniteTimeSeries_type  sourceUnit: String  unit: CogniteUnit  assets: [CogniteAsset]  equipment: [CogniteEquipment]  activities: [CogniteActivity]  acquisitionPeriodTimeZone: String  isAggregated: Boolean!  isAggregatedAtSource: Boolean  aggregationMethod: String  isString: Bo

I have set up the Cognite Pi Extractor on a virtual machine and am running into errors in the log:  Fatal error in request of type "CreateTimeSeries": Unauthorized. Unauthorized RequestId: , CDF Message: UnauthorizedI have checked that the client_id and client_secret being used in the config.yml have the ‘time_series: write’ capability for this project. Additionally, I have confirmed that the client_id and client_secret can be used with the python sdk to create timeseries in the project I am working with.Any ideas where I am going wrong?

I’ve had the OPC-UA extractor running for a couple of months with no issues. On Feb 19 it stopped pushing data to Cognite properly. According to Charts, it started pushing again on March 6. As I write this it is March 3rd. The data goes out thru June 2025,The host machine w/extractor has been restarted.The OS date/time looks correct. The log file has the correct date/time. I’d appreciate some advice.  

How is Agentic AI used in Cognite. Are there any use cases where Agentic AL is being used in the oil and gas industry?

Hi,we have quite a number of timeseries which have externalIds with spaces. Unfortunately this throws off the search algorithm of the data explorer (and also in charts when adding new data). Disallowing fuzzy search (which should not be necessary since we *know* the externalid we are looking for) yields no results. Why allowing fuzzy search for the name will give back almost all timeseries not even remotely related to the timeseries we are looking for. I tried placing quotes around the externalId without any success. Is there any way to protect the spaces in the name or to get the search to match externalIds including the spaces?

Can we use azure document intelligence in CDF documents and if I have CDF access then do azure services are free or not as AAD is assigned while creating account? 

Hello team, We have tried to query Entity view which has a property properties of type view Property which is a reverse direct relation.We are using the query endpoint and the instances.query() sdk method to do so.We want the details of properties to come in the select object of Entity. Providing the query below:{ "with": { "0": { "limit": 50, "nodes": { "filter": { "and": [ { "matchAll": {} }, { "hasData": [ { "type": "view", "space": "slb-pdm-dm-governed", "externalId": "Entity", "version": "1_7" } ] }, { "or": [ { "equals": { "property": [

​​​​​​​Can Unified namespace architecture be implemented in Cognite Data Fusion

Hi,I understand that we can define properties on edges, but it isn’t clear from the documentation how these properties are populated. I am trying to implement the following modelAnd defined the data model using DML as follows How can I add a UserActivity edge with properties start_time and stop_time, that I can read while listing all the activities that a User has performed?Thank you

Hi, I need to add the capability for read/write Timeseries Subscriptions. We are using CI/CD via the Cognite Toolkit. There is no documentation of the different capabilities for this, so I am unsure which Acl to use. I have tried “timeseriesSubscriptionsAcl” and it did not work. What is the correct Acl for Timeseries Subscriptions? Where can I find this documentation? If documentation for this does not exist, can it be created?

Hi Team,I wanted to know if it is possible to integrate Spotfire with Cognite Data Fusion. 

Lets say I have a view called ViewA, which implements CogniteSchedulable.As we know, CogniteSchedulable has the following properties:  Now, according to my requirement, I need to put a default value to the startTime and I also want to make endTime non-nullable. How do I override these settings? Since I am not managing the container definition for these containers, where do I make the changes?Any examples would be appreciated.
