Product: Cumulocity IoT - Cockpit Application
Detailed explanation of the problem:
In the widget “Data point list” the list of available data points is getting longer and longer. This list is filled with the results of the API call “supportedSeries”. Unfortunately, the list contains also the data points which are not available anymore.
Isn´t there an automatic procedure to delete data points which are not available / required anymore?
If there is, how and when is it executed?
If there is not, what would you suggest to delete old data points (no measurements are available) and keep the necessary data points (measurements are available). A manual deletion via the REST API would not be a user friendly solution.
Thank you!
Best regards,
Attila
A similar issue is described in the following ticket: After deleting all the measurement entries “c8y_SupportedMeasurements” and “c8y_supportedSeries” are not cleared. Want to delete the fragment and series names in those managed object attributes too - Forum - Cumulocity IoT - Software AG Tech Community & Forums
Hi Attila,
can you double check that the list of available data points indeed matches what the “supportedSeries” API call returns?
If that is the case, I would suggest opening a support ticket as that list should indeed be updated automatically shortly after all data for that series has been deleted.
If there is a mismatch, check if you may have manually created data points in
Hi Harald,
indeed the datapoints were used in the data explorer of one device. I deleted all the datapoints from the data explorer and I am waiting for the automated deletion of the datapoints by the platform. As you mentioned that should happen shortly after the deletion.
I am bit confused regarding data explorer now. Are the datapoints in the data explorer user specific? I mean can user_01 have different datapoints as user_02 in the data explorer? If this is the case, how can I found out which user uses the unnecessary datapoints in its own data explorer?
Thank you!
Best regards,
Attila
Hi Attila,
did the unwanted data points go away?
Regarding Data Explorer: yes, users can have their own data points in Data Explorer but these are not stored in C8Y but in the Web browser. So any data point another user has defined here, should not affect you.
best regards,
Harald
Hi Harald,
thank you for your support. The mechanism is clear now and it works as expected.
Best regards,
