“As an Hispanic user of Cognite Data Fusion, I would like to have Cognite Data Fusion onboarding material and Academy courses easily available in Spanish”

I have updated version to v2 of workflow. But still it runs v1 version.

I have a question about querying a data model using the CDF SDK.In the Cognite SDK docs there is an example for retrieving actors in a movie (https://cognite-sdk-python.readthedocs-hosted.com/en/latest/data_modeling.html#query-instances) from the following data model: But if we would change this to finding which pumps belongs to a given facility from this data model (picture below), using a bi directional relationship between facility and pump, what changes must be made to the example from the sdk docs for this to work?  

I want to create subflows after output from first function. As number of task is not fixed, curious if we can use dynamic task within workflows.Can we do it via SDK, WorkflowTask(               external_id="subtask1",               parameters=DynamicTaskParameters(                  "tasks" = "${task1.output.tasks}",               ),               depends_on = ["task1"])Is there example how task will be created and get the input from function ? I assume ‘tasks’ key needs to be send from previous function. Example will be appreciated 

I have created a calculation on charts and also created a schedule for it to run periodically. All is good so far. What I want to do now is to edit that schedule but can’t seem to be able to do that.This is a screenshot of the page where I am hoping to be able to access my schedule from. There is no ellipsis for me to click on like there is on the top calculation in the listAlso, if I open the calculation I see this. For a new calculation, the “Running on schedule” button is “Save and schedule”. For existing schedules, though, only see the “Running on schedule” and nothing happens when you click on it.So, my question is this: is there any way to edit an existing schedule?

Hello everyone! I have several binary timeseries that are displayed correctly when I ask for a short period of time: However, if I ask for a longer timespan, like a year, Charts gives me the aggregates, which I believe would be fine on some cases, but in this particular binary case, it does not make any sense. The final user cannot use this information to perform any analysis; any calculations, thresholds, or just “taking a look to see the trend” will not give an accurate result. Is it possible to choose to disable the use of aggregates for cases like this? Thank you in advance.

Hi,Could you advise me on how to fix the following error popped up from Microsoft when I get a new access token through the “Authentication” tab in Cognite API collection?AADSTS70011: The provided request must include a 'scope' input parameter. The provided value for the input parameter 'scope' is not valid. The scope {{baseURL}}/.default is not valid. The scope format is invalid. Scope must be in a valid URI form <https://example/scope> or a valid Guid <guid/scope>. I’m taking the course “Set up postman using OpenID connect” (https://lab.cognite.com/understanding-open-industrial-data/1328002)Here is my Postman setting.AuthorizationVariables 

Hello, I would like to know what is the best way to plot two variables in a XxY chart instead of stacking them. For example: I have “variable A” and I want it on Y axis and “variable B” on X axis instead of timestamp. Is it possible to do it using Charts, Canvas or should I do it on Power BI? 

Is there a tool for planning an schedulling  scaffolds ?

Hi Team,I am trying to login into Cognite Support Portal (https://cognite.zendesk.com/hc/en-us/requests/). I am not able to enable MFA for my account using Microsoft Authenticator. Please help me with the steps to do this.I am getting below window while trying to login, but not getting any code on my mobile Authenticator app. 

Is there any way to send data to cdf from blob storage using azure data factory?

I am trying to register for Cognite Data Engineer course but not able to do that because it is asking me to purchase that course with credits. Can you please help me on how to get that credits?

Hi Team,It would be a good use case to add sequences and SimInt outputs to be added to Canvas since well logs are stored as a sequence in cdf.Also, SimInt outputs are stored as time series outputs. It could be useful to include these as well.Thanks,Akash

Hello everyone.I have a use case that I have been trying to figure and I'm hoping you could help me.We have an equipment, let's say a pump, and we have a timeseries for its flow. We consider that the pump is operating as long as the flow is above a threshold.In PI, if I want to know how long the pump was operating, I can simply use PITimeFilterVal function in Excel to retrieve the amount of time that the timeseries was above the threshold. Me and my team have been trying to do this with Cognite, with no success. We tried transforming the timeseries to a 0 or 1 using the “Threshold” function, and then integrating it, but we have faced some limitations due to the approximations that are intrinsic to the integration function.Unfortunately, I cannot show you the actual data, be we checked a few days where the pump starts the day operating - at 00:00 - and at 2 am our integration gives us a value of 1.84h - when it should be as close as 2h as possible. This difference, even though slight, i

Hi guys, Could you please help me find out why it still shows empty time series even though I have insert data points? I am able to list the data points in “my_ts1” time series with API but I can’t view them in chart.How can I view the time series data in chart? Thanks a lot!

See the Product Release Spotlight post for more information.We have also added a new feature for subworkflows which you can read more about here.You can find updated documentation at Cognite Docs and Cognite API spec, replacing all earlier versions. Note that the user interface in Fusion remains in Alpha pending the development of a new version. If you lack access to the user interface, get in touch with a Cognite representative or leave a comment below.Let us know if you have any questions or comments!

Hello group members, “If you were to use CDF as an Industrial Historian, what features relating to versioning, tracking of changes and auditing would you need from our Time Series API”.In an upcoming release, we are planning to introduce support for versioning on Time Series, with the intention to enable our Time Series service to be used in the same way as you would a traditional industrial Historian.I am keen to gather information and insights from you to understand the scenarios where such a capability is required, in order that we build the right thing.  Please feel free to send me a direct message if this is of interest to you!Kind Regards, Glen

Dear Community,How do we transform or create transformation of SQL Table data with some time series values in to Timeseries Tags In CDF?Sample Data:index   datetime                   CO2      H2O                                                         0   2019-05-07 01:00:00+00:00     50.5     25.0 1   2019-05-07 02:00:00+00:00     55.0     27.7  All we need is 2 tags CO2 & H2O with 2 data points (TS) in a dataset. I can run each tag under separate transformation.Please help with SQL query to do in Transformation .

If you are one of those, who either have a big vision of maintenance transformation or are working on optimizing one part of the maintenance management process, here is a suggestion on how to optimize to meet ambitious OPEX reduction goals while building sustainable and integrated Maintenance management processes. My name is Aleksandra, and I am a maintenance domain expert in Cognite. Together with my colleagues, we have a mission to empower the maintenance ecosystem with the data and technology so maintenance professionals can efficiently optimize and transform their underlying and fundamental maintenance management processes. Here are some tips on building with the end in mind and avoiding optimization in silos. Optimize using data from multiple systemsMany companies these days are busy with the optimization of their maintenance strategy for equipment and moving it from calendar to condition-based maintenance (CBM), where possible. One way of doing it is to use a centralized conditio

Hello everyone,I created a calculated timeseries based on an existing one and everything went well, except that the calculated timeseries does not have a linked asset. As a result, when I am looking at the asset on data fusion this calculation does not show up. Did I miss something? Is there a way to link this calculated time series to the asset that I want?Thank you. 

Hello, I am working at HubOcean as a backend engineer and I need to access the logs for the API calls we make to CDF. Is there are procedure we can follow to get the logs?

Can Cognite Write back to the controller? Or in other words, is it just an open loop solution or can be integrated to work as closed loop system ?

Hi.It would be useful to access metadata from time series in Grafana. Some of our time series contain simple integers 0, 1, 2..,  and the meaning of each value is a string described in a metadata field set on the time series. Could this functionality be added to the CDF Grafana data source? Or is there a way to access this information in Grafana through another Grafana plugin? I see that there is a CDF PostgreSQL gateway, but its documentation says that it’s only for writing data to CDF, so assume this cannot be used for fetching timeseries metadata through the Grafana PostgreSQL data source?  

Hi Experts, Few queries: Can I create a ML model directly using CDF functions? - I believe we can. If yes, how can I retrain a model without using any external AI platform? Can I use workflow orchestration to retrain a model with new data? Thanks,Aditya
