Nagios to send snmp traps

Hi,

I’m new to Nagios and would like to know

  1. how to setup Nagios to send traps to other NMSes using its native MIBs that I downloaded from the Nagios website.
  2. With the following configuration, the authenication does not seem to work, it always returns me with the status message: HTTP OK -HTTP/1.0 302 Redirection
  3. I tried to see what the marco $SERVICEOUTPUT$ contains but the value is not the status info that comes back from the check_http command, it contains node10 (the hostname with a zero at the end)

Please advise and thank you in advance.

I have set up services that uses the check_http as the check_command:
In services.cfg:
define service {
use generic-service
host_name node1
service_description HTTP
is_volatile 0
check_period 24x7
max_check_attempts 2
normal_check_interval 2
retry_check_interval 1
notification_interval 60
notification_options w,u,c,r
notification_period 24x7
check_command check_http!username:Password
}

In commands.cfg
define command{
command_name check_http
command_line $USER1$/check_http -I $HOSTADDRESS$ -a $ARG1$
}
