FDM - Get Latest value

Hi,Let’s I have below data model created in FDM and there are 2 types Device and Sensor. Device is referring to other type Sensor.  Device  - name:String  - sensors:[Sensor]  Sensor  - name:String   - timestamp: Timestamp   - value: Float I have populated the data through transformation in this model. I wanted to check on how to get the latest timestamp and value for particular device and sensor through FDM GraphQL query.Example:Device : d1Sensor:name: s1timestamp:   2023-01-01 01:00value: 10.0 name: s1timestamp:   2023-01-02 01:00value: 20.0 name: s1timestamp:   2023-01-03 01:00value: 30.0 I am expecting to latest timestamp as 2023-01-03 01:00 and value as 30.0

Redirect from charts.cogniteapp.com to fusion.cognite.com/charts (starting February 7th 2023)

As communicated in this post in December, Cognite Charts is now integrated as a part of fusion.cognite.com. We are planning to retire the stand-alone url charts.cogniteapp.com to have a uniform product experience and single login. Starting February 7th 2023 you will find a message if you access the stand-alone url with instructions on how to login to fusion.cognite.com. You fill find all your charts and data intact, and Charts working as you are used to. There will be a grace period for 2 weeks after February 7th giving room for users to still access their charts from the stand-alone url if you need support to login to fusion.cognite.com.  For those of you who are linking to Charts in your third party applications, Microsoft Teams, etc., this will still function as expected. We will be working on an automatic redirect for coming releases, however still recommend you update the hyperlinks to point to your-organization-name.fusion.cognite.com already now. If you have questions on this, d

using FDM

I'm sorry, I'm new to cognite and don't quite understand the basics. FDM is one specific model with data? And if I need several models (I mean models filled with data) with the same schema, then I need to create several FDMs and then transform the data into them?

Improve error message for debugging

When working with CDF or Azure, sometimes I got some errors that were hard to figure out. Experience no doubt will help me figure them out faster, nonetheless this is an important part in enabling usability.

CDF/Cognite InField: Ability to send email to designated admin, when a User is restricted access

Is it possible to configure in Cognite tools (like CDF & Cognite Infield) to send an email with the information on the user (to designate admin(s)), when a user trying to access the tools is restricted access to those tools, for not being part of the right security groups? Question posted on behalf of Celanese user access administrator.

Give error message in Python SDK when number of datapoints more than limit

We are fetching quite a lot of data from CDF, both raw and aggregated, and we have experienced error messages from Postman and Java requests when the aggregated number of datapoints are exceeding the limit (10.000), but we have yet to experience this for the Cognite Python SDK for raw data (limit 100.000). Is there an error message implemented for this intention? From the code in the SDK in GitHub it appears that if the data is exceeding the limit then it would return an empty list, which is a very dangerous return setting. Best regardsOliver

Cognite ML: Data Modeling Hands-on Lab

I am attempting to run the python file associated with the Data Modeling hands-on lab (https://colab.research.google.com/drive/11NdrGUzFhbwsOlKqXVfYRqu9s1DzAw4b?usp=sharing). I am receiving the same error every time the ‘plot’ function is called: “TypeError: Cannot interpret '<attribute 'dtype' of 'numpy.generic' objects>' as a data type”. After some debugging, the data seems to be in a dataframe data type. I suspect there is some version discrepancy between numpy and pandas, has anyone else seen this error? Thank you, Adam

Charts: Possible bug in "constant value"

Hi, In my endeavor to make a percentwise threshold in Charts: I.e. how many percent of the last week was a time series above a certain value, I stumbled on what I think is a bug.I need to divide the time the timeseries is above a threshold by the total duration of the time window. I therefore tried the “constant value”-function, and set it to one. The default granularity is then at 7 days. I can change the granularity to 1 day as in the screenshot below:  However, when I change the granularity below this. Eg. 1 hour, I get the following warning: Ideally I want it to 1m or something like that, so that I have sufficient granularity to measure percentage above threshold over  the course of a day.Any suggestions as to how I can fix this, or an alternative way to reach my goal?Thank you

CDF deployment model for clients with small userbase

We may have many clients with small userbase. What is the suggested deployment model for these clients from below options:As all the CDF projects are isolated, should we as a single Cognite tenant create different projects for different clients. We should provision separate Cognite tenant for each client keeping future creation of multiple CDF projects over time.

Resource sharing between CDF projects

As a Cognite tenant we can have multiple CDF projects. Some CDF projects may have large user base in comparison to others. Do we need to worry about Cognite WebAPI request handling capacity.
