Course - Introduction to Cognite Data Fusion

Many organizations need to integrate and discover their IT (Information Technology) and OT (Operational Technology) data to explore and resolve operational issues. Cognite Data Fusion (CDF) streams your data into the CDF data model where the data is normalized and enriched by adding connections between data resources of different types and stored in a graph index in the cloud. With your data in the cloud, you can use the CDF services and tools to build solutions and applications to meet your business needs. This course gives you a high-level overview of the CDF architecture and data model and the main steps to fast-track your CDF implementation. Take the course and let us know if you have questions or thoughts!

Charts: What is the easiest way to configure float precision?

Hi community! I got a query from our customer that they’d like to control the float precision in Chart. I found “Round” function in “Operators” and confirmed applying that indsl to the timeseries data does work. But I’d like to ask if there is any other, easier, way because creating function per every timeseries data is a bit boring. Thanks!

Why is first day of the week a Sunday and not Monday?

Can the default option be that the week start on a Monday, or maybe give the user the ability to say what day is the first day of the week? This probably varies in different parts of the world. Where I work and live and do things; Monday is always the first day of the week :).

FirebaseError: Missing or insufficient permissions

Hi, Both a colleague of mine and I keep getting the following message for the first 10-30 seconds when we try to view the list of public charts : “Could not load charts FirebasError: {code=permission-denied]: Missing or insufficient permissions.” After some time, the list of public charts appear. This time interval can vary between a few seconds and up to over a minute. Other colleagues of us are not experiencing this issue. It seems strange that the error only occurs for a short time, but it reappears every time we try to open public charts. We have tried deleting all cookies in the web browser without this affecting the issue. Do you have any clue what could cause this?

Two of the important goals with a Data Mesh Architecture

Two of the important goals with a Data Mesh Architecture would be: Ensure that the users of data can easily find and trust the data – through carefully consider distribution of ownership and governance throughout the company/domains Ensure that data is “interoperable” across domains – to understand the meaning of data from one domain in the context of another domain. Question: What are the challenges and advantages of a Data Mesh Architecture to achieve these goals? E.g.: Domain expert knowledge and capacity within the business area/domain vs centralized knowledge Ability to make data interoperable across domains vs all-inclusive master data management Make it easier for end users to make use of the data Change management – move towards a distributed data ownership model where ownership is understood and prioritized day-to-day. Other thoughts? 👀

SOC 2, Type II

Since Cognite's start, we have prioritized security and take our security role very seriously as a partner to mission-critical industries. Today, I am happy to announce that Cognite has obtained our SOC 2 Type II certification. The American Institute of Certified Public Accountants (AICPA) bases SOC 2 engagements on its Trust Service Criteria. These criteria ensure we have rigorous security guidelines and stick with them. Type II certifications, in particular, are comprehensive and involve significant work to prepare, so a huge thank you to our team and our partners for their contribution to this achievement. At Cognite, we are investing in more automated ways to support continuous compliance monitoring. We focus on empowering our end users with industrial data operations without managing the related infrastructure. We believe it's our mission to create frictionless security, and our SOC 2 Type II certification is another significant step toward this mission!

Support for 100 requests in Cognite-SDK

Currently when fetching datapoints from multiple timeseries, the Python Cognite-SDK splits up the requests into one request per timeseries, while the underlying CDF API supports up to 100 timeseries per requests. This slows down fetching multiple timeseries, which is a problem when you display multiple timeseries (or aggregated of timeseries) in a frontend application.

What is Flexible Data Modeling?

The below is reflecting current thinking from the App Dev Journey team in Cognite and is a mental model that will likely develop over time as this topic mature. A data model enables users to customize the shape and structure their expectation of data. It plays a crucial part in building solutions (like data science models, mobile and web apps). It is also the core of an ontology, knowledge graphs, or industry standard. There are some crucial reasons why data models are effective for the industrial space. Data modeling enables explicit language, flexible customization, governed iteration, and enhanced accessibility towards data. Let's dive further into each of these qualities of data modeling. Data Model is Explicit​ A data model needs to be explicit because it provides a clear contract/interface between data providers and consumers. Hence, those loading the data and using the data can both understand the underlying data and use it correctly. By having explicit data modeling, a shared c

Solution Data Model to DMS mapping

I was thinking around the idea of adding the bindings and mappings into the Solution Data Model as directives to have more simpler syntax and UX. The idea is to “hide” the data model storage syntax and bindings syntax so everything can be merged into Solution Data Model GraphQL SDL. For example if we have following Solution data model type Person @view { firstName: string lastName: string} The following DMS should be automatically created Data model storage-----PersonTablefirstName: stringlastName: string However, if I want to make some overrides, I can use the additional directives. For example: type Activity @view @bind(filter: { hasData: { "in": "Risk" } }) { position: string @bind("dms.Table2.position") action: string line: Asset @bind("dms.Asset") equipment: Asset} In this case, in DMS, the Activity data model can be created automatically as well as the bindings and mappings to the related tables. Thoughts?

Field value history on objects in CDF.

Hey, Currently, it’s hard to maintain a coherent versioned datamodel in CDF. With Templates, and further developments there, this becomes easier. Even with a versioned datamodel it seems to me that there still isn’t a good way to track changes in the model that are not version-breaking. In our datamodel we have two types of changes that we would like to track in a structured way: Field value updates, as simple as a metadata field and as complex as the unit-multiplier on a TimeSeries changing. Edge field value updates. Our model is an adption of a RDF representation of a Common Information Model in the Common Grid Model Exchange Specification for Norway. A field on an object can imply an edge in the datamodel, and this field can change. Currently this is solvable with Labels and Start/End time on Relationships today, though it isn’t obvious that we would want to introduce an Edge type to Templates? This question is a part of the larger struggle of maintaining a sane structure on a time-

Cognites guide to code quality in Python - Part 1

Introduction In this post we share some of our internal material aimed towards solution builders, such as data scientists, who want to develop their ability to develop high quality solutions by creating more reliable, maintainable and readable code. This is the first part of 2. Motivation High code quality is easy to recognize but can be very hard to describe concretely. The assumed benefits are easier maintainability, modifiability, and more. While code style, like formatting, can be a matter of different taste, most parties agree that other code practices that fall under the umbrella term “anti-patterns” should be avoided. To stop endless formatting discussions and the like, having (and adhering to the industry) standard makes reading and understanding code across repositories easier. What this guide is not This guide will not tackle the topic of “how to set up a Python project” the right way .

[Bug] Transformation access require group "tranformations" and legacy login

We are currently migrating to OIDC where we need to give access through access groups linked to Azure AD. On our Statnett cluster it seems that a user needs to explicitly be member of a group “transformations” in order to to delete (or edit) a transformation. The admin group has the capabilities (on “test”) {'transformationsAcl': {'actions': ['READ', 'WRITE'], 'scope': {'all': {}}}}] But we need to login to the legacy login without OIDC and have a service account linked explicitly to the group “transformations” in order to delete a transformation. The group “transformations” has no capabilities set. I have tried both Fusion and the API/python-SDK (read is possible): CogniteAPIError: Transformation not found. This may also be due to insufficient access rights. | code: 403 | X-Request-ID: b7c0beb6-d3e0-9ec4-ba50-895533ac1996

How to run Cognite DB Extractor

Hi! I’m Dilini Fernando from Cognite! This is my first post, and I am super excited to share a how to guide on Cognite’s DB extractor. This post is targeted to folks who have not used the DB extractor before and wish to extract data from popular tabular databases like MySQL, Oracle, and PostgreSQL databases and ingest it to CDF. The post contains three major steps. The first two focus on setting up a database and ODBC driver, and the third step focuses on running the Cognite DB extractor. You could skip steps that are not required for you. For example, if you already have a database setup, you could skip the first step. Step 1: Setting up a database Download Micorosoft SQL Server Express Edition 2019 Install the server Note: Remember the password. You need to enter the password when you are login to SQL Server Install SQL Server Management Studio. Connect SQL Server Management with SQL server 2019.

Automated Identification & Reporting (AIR) Feature - Alert Workflow

Hello everyone, I was curious if anyone has leveraged Cognite AIR (Automated Identification and Reporting) in a way where alerts could be triggered off of other alerts? If so, how has this been done? I’d like for this to be a core feature of AIR where you can build a workflow from a visual canvas (similar to the charts function builder) and say “If this alert is triggered, check if this other alert has been triggered also” and so on. This would allow for setting up “offline conditions” so we don’t see all anomaly alerts or threshold alerts unless we can confirm the equipment is running, or even automate root cause investigations. Currently if I build an alert, I’m getting too many “false positives” of sorts that I’d like to filter out. Any input is welcome. Thank you, Richard Maidla (Hess Corporation)

GraphQL Federation with Schema Services/Templates

At release, will Schema Services support being federated into a GraphQL schema, like with Hot Chocolate or Apollo? This is how we are planning to utilize combining what is available in CDF with what we are providing in our GraphQL schemas and I was assuming this is feasible. But, a dev mentioned that the downstream services have to support being federated for it to be made available at the federation gateway. If you are using Lighthouse for your implementation, then I see it has preview support for being federated, but I need to confirm you will configure it this way or whatever you may be using will support being federated. Thanks!

Aggregation of fields

As an application developer, a very common interface to build is filtering user interfaces. There are a few types of aggregation that would be very useful to us! #1 Unique value aggregation In order to allow for effective filtering, aggregating a field by all its unique values is vital for this, to enable showing the user all possible options for a certain filter. Generally the amount of results can be limited to perhaps 1000, but having this paginate (or a higher number of 10000) would be even better! This also allows us in many cases to avoid needing expensive ‘substring queries’ on fields, as doing this in the front end on several thousand strings is trivial. Not all fields needs this, so if its required to add a `@aggregatable` decorator, then this is fine! In addition to this, having the amount of each of these values would be useful, to allow us to sort by the most commonly occurring fields. This is by far the highest priority for our use case! #2 Count aggregation Second most im

Choose what field you want to search on via @searchable

The @searchable field is a great addition! Fundamental for certain The final point to make it usable for us will be to allow the user to select what searchable field they want to be able to filter on. e.g. given the schema type Equipment { name: String @searchable @filterable description: String @searchable @filterable } Its very common that the user will know that they want to search on specifically name or description.

Feature Feedback: New Data Model Visualizer + Editor

Hello! We have worked on a new prototype experience with Templates. Data model editor We have heard feedback on the current editor UI and the lack of parity with the actual possibilities of the Data Modeling via Code. For example, there is no ability to add List, references to other custom declared types. This is all resolved via the new data model UI prototype. Data Model Visualization Another common request is to visualize the data model as a "graph" or "relationships". We have created a new visualizer to show the data model as nodes with relationships to other types. Note this does not show the data within the data model (yet) and we would love to hear if you would like this feature. Here is a Loom video to the prototype showing both features. What's next? We would love to hear if you would like to try out these features, given enough requests we may add this back to the Templates UI. Alternatively, we can also grant you access to a test CDF project you can use to try these features
