Hi, I am trying to use the Data Modeling API (https://pr-ark-codegen-1646.specs.preview.cogniteapp.com/v1.json.html#tag/Instances-(New)/operation/applyNodeAndEdges) to create instances of Views I have defined, including a reference property from one view to another. The reference property in the view looks like this:                "facility": {                    "type": {                        "space": "jca-domain",                        "externalId": "EquipmentFacility"                    },                    "source": {                        "type": "view",                        "space": "jca-domain",                        "externalId": "Facility",                        "version": "0_1"                    },                    "direction": "outwards"                }I’m not including the whole definition as it is kind of lengthy, but basically there is a Facility view and an Equipment view, and the above property is on the Equipment so I can link it to a Facility. I am able

Unable to view all the values in the source field drop down for a events page in CDF UI. In the image below , for the source field drop down,over the left side, i am not able to see all the values expected . It’s showing only few values. 

Hi… Knowing that there are locations (or remote locations) with limited internet access, what would be the recommended internet/network bandwidth for 5 concurrent users in order to deploy CDF with a reasonable performance?Any experience on this matter?Thanks Gustavo

Hi, can we load public data from cdf into mySQL

Question from an end user:What is the best way to calculate the percentage of good values for a time series over a year using Cognite Charts? I have a list of PSVs in various units that I need to see if we have data availability of at least 95% in 2022.  

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 

Hey, while performing Incremental filter operation, I am not able to get the exact filters I have applied for in the RangeStart and RangeEnd. Can someone help me out.Thanks Sharath

I work cognite reveal 3d images  in angular v12.1.1.  I using NPM  npm i @cognite/reveal@3.3.0 ,  @cognite/sdk@7.14.0 and  @cognite/potree-core@1.5.2,  Cognite reveal AxisViewTool is not working. error: (Module '"@cognite/reveal"' has no exported member 'AxisViewTool'.) 

Hi,Cognite grafana plugin internally use synthetic timeseies api while passing query under “time series custom query” option. but synthetic timeseries api returns error while trying to retrieve data-point for string timeseries. please check out attached screenshot.

I’m creating a new chart “speed” by calculating the absolute values from “velocity” chart. This is one of the exersie from “Cognite Charts” training course. However,  the values generated from the “Absolute value” are not correct, for example, in the screenshot below, the vlaue of “Velocity” is -1.5074… but the value of “Speed” is 97.3128 .. instead of 1.5074... 

Is there a way to query FDM either using sdk or rest APIs? Is there any documentation or examples available?

Hi,I have data in raw table in this format:Table1:id p1 p2 p3 1 2.0 3.0 4.0 2 10.0 15.0 20.0  I wanted to transform this details into following format through transformation id property value 1 p1 2.0 1 p2 3.0 1 p3 4.0 2 p1 10.0 2 p2 15.0 2 p3 20.0   so I have written following transformation query:SELECT id, property, valueFROM `db1`.`Table1`UNPIVOT (value FOR property IN (p1, p2,p3)) UP This query works in SQL studio, but in COGNITE transformation UI , I see below error:Mismatched input 'FOR' expecting {')', ',', '-'}(line 3, pos 15) Can you please help to understand what is missing in this?

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?

We are looking for OID and/or subset of Bootcamp data to be loaded and available in our project Cognite environment for further exploration. Can you please create a support ticket for the same?

How can I execute two or more different queries extracting the data from the source and inserting the data in the same CDF RAW table?Currently only the last query available in the config.yaml file gets executed. 

Do Cognite OData APIs also offer have cursor implementation like cursor capabilities on REST endpoints?

Hi! I would like to check if a time series stays within a region for more than a certain amount of time. Is this possible? This would be the equivalent of inverting the “Upper lower threshold” function. Also I would need a time limit for that. Perhaps it would be a simple yet powerful addition to the existing functionality: To be able to invert the monitoring task? Some of the monitoring tasks have a time aspect, and some do not.. perhaps all should have it?  Regards  

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.

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

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

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

Hello @Kristoffer Knudsen @ibrahim.alsyed  would like to know if Cognite InField would work ok for demo purposes on a giant smartphone (android  55’’)Celanese is planning to demo this to 100 people using something like this https://www.giantitab.com/ cc: @MortenNesvik @Kriti Dhaubhadel @Philippe Bettler @piya dey @Ajo 

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. 

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.
