Solved

I am trying to connect to an MQTT broker with Cognite’s MQTT Extractor.I know that the broker is fully functional, verified by several tools.However, when completing the “Add MQTT Topic”.Error code indicates that the API does not accept “Datapoints” as “Target type”, even though “Target type” is a mandatory field in the interface window. And: “Datapoints” is the only available selection.Any quick feedback to progress my testing is appreaciated! 

Hi Team, Greetings of the day!!I’m learning the cognitive charts, but I’m unable to find the cognitive chart neither in Explore nor in All category.Can you guide me to find the navigation?Regards,Navin

We are having a multilevel asset hierarchy in cdf, and ground level assets are only having timeseries linked.we are trying to create Relationships between every parent asset and its child asset’s Timeseries.we used python sdk code snippets to do this. Which are been attached to this for your reference.In python sdk, after running the python relationship code, it is showing relationships are established. But in UI it is not showing from Assets, But we are able to see under Timeseries.even after we tried interchanging the Source and target between assets and timeseries, same result.one unique observation is that we could see the relationship established just for 1 asset which is having 3 timeseries linkage. rest others are not showing(they have more than 20 relations, even 500 for root asset.)we would like to know are we following correct manner, or any restrictions are from CDF tool. plz help us in this regard.from cognite.client import CogniteClientfrom cognite.client.data_classes impo

Hello I am trying to run entity matching on the data that is in FDM (Data modelling) and not in the classic assets model. I don’t see an option to fetch such items in the entity matching screen (contextualize menu). Is this by design, do we expect a support to search and select such custom models for matching in the future. Also a similar case for data explorer, even when I have updated all my records to have a data set id, I am not able to search for them in the Data explorer. Just wondering when the explorer can start supporting such data. PS:I imagine, the entity matching can also work if I invoke the APIs directly,  but then I’ll have to extract names + description myself and also need to link the results back to their original ids. A visual ways in CDF Fusion UI will be very helpful. RegardsAlex 

Hello All,In the past, we encountered some performance issues when extracting data from the PI System using PI API. As an alternative, we have been using PI SDK to extract data from both PI Archive and AF. The question is, does Cognite PI Extract utilize PI SDK, and are there any performance limitations?

How to keep Master data in CDF: the data which is not part of any asset hierarchy 

Hi,We saw quite frequently an error message like below:"could not add instances: 500 - Internal server error. Please report this error to support@cognite.com and provide us with your request id: 4594f717-51c0-9708-86d3-5c5431f60cd1 and cluster name: westeurope-1"But when run it again it worked. The issue happens quite often(the number of instances in the request is close to 1000), could you have a check? Thanks. Regards,Xiaofeng 

Hi, is it possible to host a web-hook endpoint in a Cognite function?And is it a good idea?

When I try to open the link provided in this chapter, I’m just getting this error message: Link:Error: A sign-in box is showing briefly, for about 1 second, but is interrupted by the error after. What do I do about this? I tried another browser with the same result, so maybe just try again later?

Who can see the InField application configuration settings? All users?Received feedback from learning facilitators today that they would rather their operators not even have the option of viewing (to further avoid changes to configuration, etc.) We assume access groups determine who can actually toggle the config settings, correct?

I am following the Cognite training and trying to create the asset data transformation. when hit Run bottom it shows a different error on each run. can understand what is the root cause and the mitigation action. Appreciate feedback. Thanks ever display the exactnumber of 36 rows we have in the asset.csv file

I had run transformation giving me error for Duplicate node externalIds for space 'PDM' even after deleting all the data from the model for space PDM still giving the same error, I also verified by api still there is no data still giving the error for Duplicate node externalIds for space 'PDM' . 

Currently Cognite’s Streamlit apps have issues with for example:with st.spinner('Wait for it...'): time.sleep(5)st.success('Done!')The code itself should wait 5 seconds before writing out Done!, but is executed instantly. Another example is when you try to make your application responsive while waiting for some data to arrive from a remote location. For example, when you want to print out a wait message for the user because sometimes it takes some seconds to load the data, but the app doesn't work as intended. In the following example I am trying to print out a message while waiting for the function to finish, but it fails:call_func_button = st.button("Call function with current parameters", key="button_func_call")if call_func_button: func_call = example_function.call(data=input_data, wait=False) st.info("Waiting for function...") while func_call.status == "Running": func_call.update() if func_call.status == "Failed": st.error("Function failed to run!")

I wanted to know, can I create a Table in RAW database, which will contain only column names initially with 0 rows added in it?

We’re in development of an API retrieving the latest values from timeseries from CDF using the C# SDK. Initially we set the code to look 200 days back (‘200d-ago’). Now, this stopped working all of a sudden this week. My first reaction was to go event further back (‘365d-ago’), but what works is using an even shorter timespan (‘30d-ago’).So question is - are we limited by a quota or have there been changes limiting this functionality lately?

I have a CDF chart that is showing some output based on the timeseries associated with. I want to flag the points on the chart that are beyond some threshold. (say anything >0.5 and <-0.5 is abnormal and need to be flagged off in the chart) IS there a way to show that in the CDF charts visualization.

  Getting above error whenever trying to reach documentation

Have been having issues with Cognite Charts since it’s been merged into CDF. Whenever I try to go to charts, I have to clear the cache in my browser for it to work, otherwise it doesn’t load. This is a small nuisance that can prevent people from adopting the use of Charts as their daily tool.

There is a requirement for me where the stakeholder wanted to download all the charts (120+) in one-GO for a specific date range and then validate them. There are some charts (out of 120+) that are using the timeseries objects with some calculations. (ta * tb) /1000 , (ta + tb + tc)/1000 , 141/(ta) - 131.5,…… I cannot go to each one of them manually and download them, but the customer wants to download them all in one and then validate as per their choice.  Please advise
