All the check_local_* commands that you are running are checking the
Nagios server, not the remote server.

To check remote servers, you have to install/setup some way to execute
checks (NRPE, check_by_ssh, SNMP) and run a check against it. The
plugins will have to be installed on the servers themselves.

All network-based checks (check_ping, icmp, tcp, http, smtp, ntp, mysql,
etc.) can check a remote host which is specified with the -H (or
- --hostname) parameter. All other checks runs locally.
