Integrated Data Lake¶

Applicable for:

• Subscribers of Integrated Data Lake

Known issues¶

• In Time Series Import user interface, the user can only view first level of child asset at the moment when importing the time series data. The workaround for this approach is to use backend API to import data related to multiple child assets

IoT and Storage Service: File Service¶

Applicable for:

• MindAccess IoT Value Plan Subscribers
• 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 Service: Time Series Service¶

Applicable for:

• MindAccess IoT Value Plan Subscribers
• MindAccess Developer Plan Subscribers
• MindAccess Operator Plan Subscribers

What's new?¶

IoT Timeseries Aggregate API v4 Enhancement:

• Precalculated aggregates are available in the following aggregate intervals
  • 1 minute
  • 1 hour
  • 1 day
• Limitations:
  • The maximum time range for querying DAY/WEEK/MONTH aggregates is 365 days.
  • The maximum time range for querying HOUR aggregates is 30 days.
  • The maximum time range for querying MINUTE aggregates is 48 hours.

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.

Java SDK, Python SDK¶

Applicable for:

• MindAccess Developer Plan Subscribers
• MindAccess Operator Plan Subscribers

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.
• Assets data from asset management has a page size of 200, if a assets belong one tenant are more than 200, Root asset area may display empty when create project.

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 log in 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.
