Cognite functions

I want to create a cognite function that will do lot of computations and finally attach the derived output to a timeseries. Is there some production-ready sample code snippet that can be shared to see how to attach a derived value from cognite function to a timseries?

Question: How to Leverage Drawings that are Contextualized and LIVE and Hotspotted?

scenarios we are working on, To show PI&D diagram with annotations, which help to select the asset and create a threat for that asset. Or draw a rectangle over the PI&D diagram to select multiple assets. For the above two scenarios we are referring APIs in,https://docs.cognite.com/api/v1/#tag/Engineering-diagrams Quickstart — cognite-sdk 5.3.1 documentation (readthedocs-hosted.com) We are successful in getting the PI&D as image by following the below steps,1. List Fileshttps://api.cognitedata.com/api/v1/projects/{project}/files2. Convert a diagram to image formathttps://api.cognitedata.com/api/v1/projects/{project}/context/diagram/convert/3. Get the results for converting an engineering diagram to an imagehttps://api.cognitedata.com/api/v1/projects/{project}/context/diagram/convert/{jobId} Could you please guide with APIs / JavaScript SDK methods we need to work on for the above mentioned two scenarios.

Python API calls work in Jupyter Notebook, but fail when running as a Python script

I have some code working great via a Notebook, but I want to move it to a server where I can run it as daemon. The authentication is failing when I run it on the server.I suspect the problem is with the Scopes - User impersonation might work in the browser where I’m already logged in to the right project. What scope should I use instead when I’m calling directly from Python?Also tried myscope = '[f"https://westeurope-1.cognitedata.com/.default"]'as suggested in the documentationoauthlib.oauth2.rfc6749.errors.AccessDeniedError: (access_denied) Unauthorizedfrom cognite.client import CogniteClient, ClientConfigfrom cognite.client.credentials import OAuthClientCredentialsfrom cognite.client.data_classes import TimeSerieshost = "https://westeurope-1.cognitedata.com"myproject = "rok-buandcollaborators-53"clientid = "realStuffWasHere"secret = "secretsecretsecretsecretsecretsecret"#myscope = "https://westeurope-1.cognitedata.com/.default"myscope='["IDENTITY", "user_impersonation"]'token="https

How to add externalId to a Timeseries

I created a set of timeseries via the API. The Python examples do not show how to include an externalId nor do they say one is really needed. Looks like they need one, otherwise they don’t work in Charts. That’s all fine. My problem now is to add the externalId to existing timeseries.I think the right way to do this is with a transform, but I can’t get it right. I can get it to preview correctly, but it fails when I run it.My transform is:Select name as name, concat(name,"123") as externalIdfrom `_cdf`.`timeseries` where dataSetId = 8883655420989208;The error is Request with id 2463250f-1635-9a05-aa9a-709366e80349 to https://westeurope-1.cognitedata.com/api/v1/projects/rok-buandcollaborators-53/timeseries/update failed with status 400: Time series not found. Missing externalIds: [Tank-401-01-TT123].Looks like it’s trying to query for the timeseries with that externaId when I’m trying to set the externalId. How do I get it to set the value?

Timseries linked to an asset

How to fetch all the timeseries linked to an asset? I have a root asset that has 16 child assets. Each of those child has 18 timeseries objects. How do I write a code so that I can loop through this setup and read each of those timeseries objects and read the datapoint for a particular day and gather them. root = client.assets.list(name='liquid_asset')children=client.assets.list(parent_ids=[root[0].id])for i in children: print(i.time_series)Result is this: <bound method Asset.time_series of <cognite.client.data_classes.assets.Asset object at 0x3468500>>I could not iterate through the i.timeseries and read the datapoint from a very specific timeseries object named as 'PVOL'. Please help.

Limit on adding instance API call

Hi,Currently we have a limit on the POST models/instances where we only allow to post 1000 instances at a time.This operation is currently limited to 1000 nodes and/or edges at a time.Normally between the instances there are dependencies so it is not very easy to split the request to multiple calls. Do you think it is possible to lift that limit to a big number, f.ex. 10000? Regards,Xiaofeng

Retrieve dataframe from RAW table

I uploaded a CSV into a raw table in cognite data fusion. Now I have seen the raw table and see 200 numeric columns and 2 text columns are present. When i come to SDK and retrieve the rows from the same table as dataframe, it is showing 199 columns as numeric and 3 text columns. there was one specific column '0NA' which was originally a numeric column now shows the datatype as 'object' instead of 'float64'. I checked and there are no null values and no other NaN characters and it's just decimal values all across. When I fetch all numeric columns directly from CSV, I see the column as float-64 but after importing that CSV into RAW table, it is doing something else. I tried to see the unique values in the column and found these two as string,I suppose. In CSV , they were stored as number but when uploading to RAW table, it does convert into something like this. Please help if RAW table cannot accommodate values with more than 10E142 values such as these?. How to handle this scenario.'241

FDM Graphql - Edges - Limitation over the number of edges fetched (only 50) when it is as a nested property

Hello,We are trying to fetch the edges of an view in a graphql.But graphql is returning only 50 edges at max. We see the cursor option in graphql, but it seems that it has been not implemented and is giving null even if there exists more data.So question is - When the cursor functionality for edges will be avaialble in graphql or some know issue as of now ? If this is a limitation how do we get edges data joined with the view data where the edge is present using the rest endpoints. Any best combination suggested as there will be multiple stages to resolve the cursor and the edges data, as we understand it.Request your quick ideas on this how it could be achieved.

Pagination and returning records at a specific page

Hello data modeling team, I tried the "first" and "after" filter on Query Explorer which enables us to retrieve the query result page by page, it works well.while we have an existing API which enables the consumer to specify an "offset" and a "limit" parameter. by the offset, the consumer could retrieve records at any specific page without the need to always go though from the beginning and then retrieve page by page, it's like the skip and limit syntax in mongodb, for example, db.myCollection.find().skip(200000).limit(50).we want to keep the API behavior so no modification needed for existing consumer, while we do not want to simulate the offset behavior by retrieving page by page within our own API since it will be very low efficient when there is a big dataset, so is it possible to provide the offset supporting in Cognite ? or any suggestions/methods we could try to implement this ? Thanks!

Guidance Needed: Implementing Time-Series Analysis with Cognite Python SDK

Hello Cognite Community,I'm currently in the process of deepening my understanding of the Cognite Python SDK, and I've encountered some hurdles that I believe this community could help me overcome. I'm working with a time-series dataset and aiming to use it to make machine learning-based predictions. To facilitate a more comprehensive response, I've provided a snapshot of the data I'm working with and detailed my queries below.Dataset Structure: The data comprises 5 columns: time, ws_E05, ws_E06, wp_true_E05, wp_true_E06. The 'ws_E05' represents the true wind speed at location E05, and 'wp_true_E06' signifies the true wind power at location E06.Query 1: I plan to utilize this dataset to forecast the subsequent 10 minutes using Linear Regression in the Python SDK on Cognite. Could you advise me if the present state of this time-series data is sufficient to get started, or are there certain modifications or preprocessing steps I should consider? I'm also interested in visualizing this da

OPC-UA Extractor Issues

Attn. @Jatin Sablok We found some issues with the Cognite pre-built OPC-UA extractor’s automatic re-connection to OPC server and to CDF as detailed in the test cases below.OPC-UA server reconnect test: OPC server is online and Cognite OPC-UA extractor is started. Then OPC server is restarted. Cognite extractor loses connection to OPC server, and is unable to re-connect automatically even after OPC server comes back online later. Extractor service has to be manually restarted to re-connect to OPC server.CDF reconnect test: Cognite OPC-UA extractor is started with network connection cable to CDF unplugged. Extractor log shows error messages. And extractor is unable to connect to CDF automatically even after network cable is plugged back in. Extractor service needs to be manually restarted to connect to CDF.Logs from both tests are attached. Could you please review them and let us know if these are known issues?
