I am running Openhab on a Pi 3 (live server) and on a Pi 1 (test server).
I am thinking about the following hot standby:
I want to install a second Pi 3 (backup server) which is a full mirrow of the live server, but with Openhab inactive.
The test server frequently checks whether the live server is up.
If not it pushes a file to the backup server and a cron job on the backup server activates Openhab.
I know that with the Network binding I can ping the live server and see whether it is up.
But that is the whole server, not Openhab itself.
Is there a way how the test server can check whether Openhab is down on the live server, even when the live server itself is still up?
