Are you running check_ping while logged in as user "nagios"?

All Nagios plugins return:
 0 == success
 1 == warning
 2 == critical
 3 == unknown

And "-1" (aka "127") is commonly returned by the OS when "exec" is done
to run an application but it can't be found. So it sure looks likely
that when Nagios goes to run check_ping, the command cannot be found.

On my installation of Nagios, the plugins are all in
  ~nagios/libexec
and the check_commands file uses:
  $USER1$/command_name
and file "resource.cfg" defines $USER1$ to be the libexec directory.

Simon
