check_ping necessary?

[Don Schultz]

This may be a really stupid question but I'm going for it anyways ;)

Is it necessary to define a "ping" service for hosts? If you do not,
aren't they still pinged with the check-host-alive command or are they
just assumed to be up by the nagios process? 

If I'm thinking correctly, then the only way to get notification of a
host being "down" is to include it in a ping service definition correct?

Thanks!
