Recognising errors/terminations in the container

[z-master42]

Is there a way to register errors/script aborts within the container?

I occasionally have the problem that the connection to the Zendure Broker fails (as far as I can tell, it tries to reconnect for a while) and the script then stops working.

Unfortunately, the container just keeps running and doesn't exit, so I don't notice it directly.
