define command{
command_name check_ping
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w 3000.0,80% -c 5000.0,100% -p 5
}

ademas en mi archivo localhost.cfg definí el servicio
define service{
use generic-service
host_name CENTRAL.CISCO,ACC.POINT,anexos
service_description PING
check_command check_ping!1500.0,80%!3000.0,90%
normal_check_interval 5
retry_check_interval 1

la pregunta es que si hay redundancia o como se deben plantear
por tu ayuda anticipo mis agradecimientos

Whoops!

Error: Could not read host and service status information!

The most common cause of this error message (especially for new users), is the fact that Nagios is not actually running. If Nagios is indeed not running, this is a normal error message. It simply indicates that the CGIs could not obtain the current status of hosts and services that are being monitored. If you’ve just installed things, make sure you read the documentation on starting Nagios.

Some other things you should check in order to resolve this error include:

Check the Nagios log file for messages relating to startup or status data errors.
Always verify configuration options using the -v command-line option before starting or restarting Nagios!

Make sure you read the documentation on installing, configuring and running Nagios thoroughly before continuing. If all else fails, try sending a message to one of the mailing lists. More information can be found at http://www.nagios.org.

dejame agradecer este tutorial, está excelente, ya entendí claramente todo, estaba estancado en algo muy básico y me sacaste de todas las dudas, ahora de aqui al infinito y mas allá.
