COGNITE MAINTAIN

Does it make the data available for optimal maintenance scheduling, or does it automatically generate maintenance plans based on that data? Does it predict failures?

Does Cognite Unit Catalog can support relative measure units ?

Hello, We currently have the need to support radioactivity timeseries that are measured with the gAPI unit. What is gAPI? • API (American Petroleum Institute) units are commonly used in the oil industry to indicate natural radioactivity in geological formations, particularly using gamma ray logs.• gAPI stands for giga API units (1 gAPI = 10⁹ API units), but it’s often a confusion — in most cases, gAPI simply means “gamma API units”, not giga.• In well logging, 1 API unit is a relative measure, not an absolute unit of radioactivity like Bq. This makes gAPI very difficult to integrate to the CDF unit catalog (https://github.com/cognitedata/units-catalog). Since we cannot have an absolute conversion to an SI unit. This conversion depends on  calibration curve or lab measurement linking the gamma ray count in API units to disintegrations per second (Bq). My question is: is there a way to support this in the unit catalog? Support of units without conversion to a SI unit? It is very importan

Issue with activities Field in CogniteAsset View – Invalid Reverse Relation

Hi everyone,While querying the CogniteAsset view, I encountered an error when including the activities field in the selection. The API returns the following message: "Cannot traverse lists of direct relations inwards." Upon investigating, I noticed that the activities field in the CogniteAsset view is defined as a @reverseDirectRelation: activities: [CogniteActivity] @reverseDirectRelation(throughProperty: "assets") In turn, the assets field in the CogniteActivity view is defined as a list of direct relations:assets: [CogniteAsset] @directRelationThis makes sense as the root cause, since reverse traversal over a list of direct relations is not allowed, which explains the error.Given that this field leads to an invalid query pattern and always results in an error, should the activities field be removed from the CogniteAsset view to avoid confusion and runtime errors? Here’s a minimal query that reproduces the issue:query MyQuery {  listCogniteAsset {    items {      aliases      activit

The extractor utils requires a config file path, no way to pass the config object directly

The python extractor utils requires the config to be stored as a local file there is not way to pass it directly as a string/yaml object. This makes it quite cumbersome to use as not all our deployments have access to local file storage for config files.Is there a way to add support for the config to be passed as an environment variable? Reading config from env example:

How to get the latest graphql url of a minor data model ?

Hello, We envision to implement a versioning based on minor and major version of our data models. So a data model version will be presented with two digits: <Major>.<Minor><Major>: incremented when we do a breaking change that is not backward compatible with the previous one and we know that it will break our consumers queries. Exp: delete an attribute in a view in the data model<Minor>: incremented when we do a change that is backward compatible and consumer queries will not break. Exp: add a new field. Is there a way to get a graphql url that maps always to the latest minor version of a given data model? This will avoid our data model consumers to redeploy their application every time we increment our minor version.  Thank you!

Using nested attributes from linked objects in index definitions

Hi all,I have a question regarding the use of nested attributes from linked objects when defining indexes.In my model, I have an object Cement that has a direct link to another object called ScenarioContent.I would like to use the attribute ScenarioContent.Type as part of the index on the Cement object.This is particularly useful, because I use views that filter Cement instances based on ScenarioContent.Type. For example, to expose only planned scenarios, I use the following rawFilter in a view:@view(  rawFilter: {    nested: {      scope: ["Cement", "ScenarioContent"]      filter: {        equals: {          property: ["ScenarioContent", "Type"]          value: "PLANNED"        }      }    }  }) Question:Can I use this nested attribute (ScenarioContent.Type) in the index definition of Cement?If this is not currently supported, is there a recommended alternative to support performant queries on this kind of filter?

Newly encountered Read Timeout error

Hi Hub, We have some backend code running as a Github Action that fetches events using `clients.events.list` over a period of 1 year. The fetching is of course chunked into smaller time frames to avoid memory overload. This has worked just fine until recently where we are frequently encountering aCogniteReadTimeouterror, which can be traced back to the following HTTP request error:requests.exceptions.ReadTimeout: HTTPSConnectionPool(host='az-ams-sp-002.cognitedata.com', port=443): Read timed out. (read timeout=30)The error occurs inconsistently and not necessarily at the same point in time of the workflow run. Have there been any recent changes/restrictions in the Cognite SDK that could explain the cause of the issue? As mentioned, some weeks ago the workflow succeeded without problems. For additional context, we are using multiple threads to fetch events in parallel over metadata, for events within same time interval. Also, we use multiple cores to parallelize fetching and subsequent

Deploying functions with toolkit

When deploying a function with the SDK you can specify the source code “folder” as a parameter. I have used this to deploy the functions with my own python module which is just a directory with some py files. I want to migrate to using the toolkit, but I am not sure how to deploy with the source code folder I want as I do not see a way to specify it in the yaml file. Can anyone help with this? I have multiple Cognite Functions that I want to deploy that all access the same source code I have written.Thank you!Sebastian

Getting accurate metrics from a completed transformation in the same workflow

We are trying to implement automatic monitoring over our transformations in CDF. We are doing this by running a transformation and a monitoring function in the same workflow, where the monitoring function is dependent on the transformation being finished.Then we retrieve the sum of updated and created events like this: def _created_and_updated_sum(self, transformation_external_id: str) -> int: """ Get the sum of the number of created and updated events in the last transformation job. If there are no finished jobs, return 0 instead. """ transformation = self.cdf_client.transformations.retrieve( external_id = transformation_external_id, ) if transformation is None: raise ValueError(f"Transformation {transformation_external_id} not found") if transformation.last_finished_job is None: DUMMY = 0 self.logger.info(f"Transformation {transformation_external_id} has no finished jobs.

Alerts & Monitoring: CDF Charts

I noticed a few misses / potential improvements in the alerts & monitoring section of Cognite charts - Was wondering if anybody else had similar experiences?Email alerts always come in UTC (Considering we are based out of India, we may miss important alerts because of this). Let's say I have an Asset where I have generated a chart (in our case a particular well from a particular lift type showing critical parameters). A filter-based option where I can just switch Wells showing - using the same parameters as tagged before.
