The default host-alive check is a ping test, so you are essentially checking the same thing twice, yes. However, hosts checks are normally only checked when a service check fails, to see if the host is up or down (which would explain why the service check failed). So your service check ping is checking, and only if it fails does the host ping check get executed.

There is nothing wrong with your approach.

Thanks Eric. @HenkR is there anything else we can do for you?

No, thanks for the information
