All supported DX NetOps Performance Management releases
Unable to reproduce or determine root cause.
Engineering suspects there were problems, or missing values, in the /var/.com.zerog.registry.xml file on the Portal web server host during the install run.
After reviewing it post install the expected values are present. Suspicion is that it was updated through the upgrade, despite the errors, and the error was benign.
Post upgrade, despite the error, all functions are working properly.
This has been resolved by engineering in release 21.2.12 through defect ID DE534932.
