Server A application is active, Server B application is not running. Server X application is not running, Server Y is not running.
I need to alert on Server A application not running and any other server (B,X,Y) application taking over. It should also alert on the next application release and takeover.
If this is more than 1 alert, that is fine but, I don't need false positives.
The action should be an email/text that contains the previously active server as well as the server that has taken over.
Right now, I have one alert that tells when the application on any (of the 4) server goes down and another alert that notifies when any (of the 4) change to the running state.
I am looking for a better way.
Thank you.
