  • The event time stamp in the Event extension shows only in format of UTC even if user chooses "Browser (+08:00)" (China for example) from the time zone drop-down.

IoT and Storage Services: File Service

Applicable for:

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

Known issues

  • For security reasons a strict timeout is enforced. Currently this leads to the situation that the size of a file which can be uploaded/ downloaded depends on the network bandwidth at client side.

  • After deleting an asset, associated files might still be accessible for up to 30 minutes as this data is deleted asynchronously.

  • Multi-part uploading or completing may failed with “500 Internal Server Error”. To avoid such failure, please make sure some interval (e.g 3s, must be greater than 1s) between each part uploading request or before completing the multi-part uploading.

IoT and Storage Services: Time Series Service

Applicable for:

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

Known issues

  • The maximum payload size of a message sent to time series service as part of a PUT request cannot exceed 1 MB.

  • The service will never return more than 2000 records in a response

  • After deleting an asset, respective time series data might still be accessible for up to 30 minutes as this data is deleted asynchronously.

  • When getting the job status of a bulk import job, the response might not always contain detailed information on errors that occurred.

  • When using “select” parameter in GET method of Time Series API, the response might not always contain all the data in the below scenario:

    There are 3002 time series data in the given time range of GET method, the earliest time values "_time1" and the latest value is "_time3002". There are only 3 "var2" as in below table. When "var2" is considered by “select” parameter, only "var2" from "_time1" would be returned.

    _time1

    va1

    var2

    _time2

    va1

    var2

    _time3

    va1

    var2

    _time3000

    va1

    var2

    _time3001

    va1

    var2

    _time3002

    va1

    var2

Java SDK, Python SDK

Applicable for:

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

What's new

  • Java SDK 2.3.7

    • add client support of iotbulk

    • add client support of mindconnect

  • Python SDK 1.0.4

    • add client support of iotbulk client

    • add client support of mindconnect client

Known Issues

  • Auto-deployment does NOT support 1) applications using binary buildpack, 2) appliations that has "buildpacks" attribute in manifest.

  • Application upload artifact with Chinese filename will fail to check.

MindConnect Edge Analytics

Applicable for:

  • MindAccess IoT Value Plan Subscribers

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

Known issues

  • Note: A full configured monitoring of the Analyzing Packages Vibration Characteristic Values and Vibration Frequency Spectra with all channels of one SM1281 can exceed the CPU performance of the MCN. Also in other scenarios dependent of tasks running in parallel on the MCN, CPU load can get to high. The recommendation is to use only two full configured Vibration Frequency Spectra Analyzing Packages in parallel.

  • Note: A compatibility check, whether the Edge Analytics Engine Version on the target MCN supports all possible types of Analyzing Packages, which are offered by EAM, is not yet done. Therefore it has to be made sure that the newest Firmware Version is installed on the MCN when using the new Analyzing Package Vibration Frequency Spectra, otherwise the Edge Analytics Engine will suspend.

Notification Service

Applicable for:

  • MindAccess Developer Plan Subscribers

Known issues

  • Currently only email text is checked, other contents like image, audio, video, URL are not in the validation scope.

Operator Cockpit

Applicable for:

  • MindAccess Operator Plan Subscribers

Known issues

  • If you download application binaries during manual deployment the progress bar of the download progress of the Operator Cockpit is temporary disabled. The download will be executed but without a feedback of the progress in the Operator Cockpit. Look into your download folder to find the application binaries.

  • Limitations for applications that use "Technical Token Manager API"

    • You cannot use zero downtime upgrade for applications that use "Technical Token Manager API", if the previous version of this application did not use "Technical Token Manager API".

  • Limitations for update of Cloud Foundry applications:

    • The service instance names for each service should be same in the current and new version of the application. If the service instance names are different in the new version and the existing version of an application, then the existing service instances will not be readily available even after zero-downtime version upgrade.

    • During manual deployment of a new version of an application, do not use the same component names as available in the existing version. This might create name conflicts and usability issues. In order to avoid such conflicts, while deploying a new version of an application, append green at the end of the component name.

  • For every individual (single) application, one Cloud Foundry space must be deployed.

  • After modifying the authorization of a user via the Operator Cockpit user interface, the change is not immediately visible. The user has to close the browser and login again.

  • After deployment of an app there is a security feature in place validating if the app is known to MindSphere or the app got somehow modified. Sometimes issues occur with regards to name changes or deploying from various folders. The apps need to be deployed as they are assigned from the developer.

Subtenant Functionality

Applicable for:

  • MindAccess IoT Value Plan Subscribers

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

Known issues

  • Applications can use the subtenant functionality via the provided APIs. Tenant administrators should pay attention when assigning such apps to subtenant users as subtenant isolation cannot be ensured by the platform. The app might expose data to the user that is not intended to be seen.

  • When moving an asset from a parent tenant to a subtenant, there might be a delay of up to 30 minutes until a subtenant user will be able to see data related to that asset.

  • Please be aware, if you provide a user (even subtenant user) the role "mdsp:core:TenantAdmin", this user is then able to get access to all kinds of tenant data.

Usage Transparency Service

Applicable for:

  • MindAccess IoT Value Plan Subscribers

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

Known issues

  • Time used for usage information storage and displayed on UTS UI is only using UTC time zone, not depending on the time zone of the region.

  • All usages generated within a Cloud Foundry Environment cannot be collected by Usage Transparency Services. All usages from and to a Cloud Foundry Environment e.g. requests to APIs still will be collected.

  • Usage Transparency Service reports are only available after a 1-hour delay for developers.

  • Customer Dashboard does not cover all metrics and upgrades that UTS measures for a tenant. We are continuously working on introducing more metrics and upgrades.

Visual Explorer

Applicable for:

  • MindAccess IoT Value Plan Subscribers

  • MindAccess Developer Plan Subscribers

  • MindAccess Operator Plan Subscribers

Known issues

  • The "share via link" functionality works unreliable.

  • Support time series data types “LONG” with values for safe integer ->(253-1) to (253-1).

  • If the value is e.g. 263 the value will be reset to safe integer ->253-1.

  • Alerts can only be set up by clicking on a continuous axis.
