Add Kafka and TL-Sync status to monitor page

Monitoring TLSync

The Monitor page displays, among other things, the status of various parts of the application. The status of Kafka and TL-Sync should also be displayed there. A distinction should be made between the two. Although Top-Logic primarily uses Kafka for TL-Sync, Kafka is often used for other types of data transfers within the applications as well. Therefore, the message “TL-Sync cannot send” is not the same as “Kafka cannot send.”

Implementation

Example for multiple errors:

Example with only one error:

Example with no errors:

<context>/SystemState.jsp?showInfo=true (If everything is OK, only “OK” is displayed otherwise):

Test

Go to the Monitor page in the Kafka demo and verify that there are at least two entries each for Kafka and TL-Sync: Send and Receive.
Start ZooKeeper and Kafka. Make a change that must be transmitted by TL-Sync. Verify that the new monitors do not display any errors.
Start without Kafka. Make a change that must be transmitted by TL-Sync. Verify that the new monitors display errors.
