Restoring the Embedded Sensor after the upgrade in distributed solution and multitenancy mode

Embedded Sensor may be missing after upgrading a Central Node component that had been used in the distributed solution and multitenancy mode to version 7.1.1, 7.1.2, or 7.1.3.

To remove the limitation:

1. If, after upgrading the Central Node component, the Embedded Sensor is present but dsabled, remove Sensor in the web interface.
2. Sign in to the management console of the Central Node server on which you want to upgrade the Embedded Sensor over SSH or using a terminal.
3. When the system prompts you, enter the administrator user name and the password that was specified during installation of the component.

   The application component administrator menu is displayed.

4. In the application administrator menu, select Technical Support Mode.
5. Press ENTER.
6. This opens the Technical Support Mode confirmation window.
7. Confirm that you want to manage the application in Technical Support Mode. To do so, select Yes and press ENTER.
8. Run the following command:

   docker service update --cap-add=CAP_DAC_OVERRIDE --cap-add=CAP_IPC_LOCK --cap-add=CAP_SYS_PTRACE kata_product_main_1_preprocessor_span

9. If the Embedded Sensor was not restored, clear the databases by running the following command:

   kata-sensor-tool reset-core

The Embedded Sensor is restored after approximately one minute.
