Multiple Interfaces

[Richard Gliebe]

Hi there,

I want to define the hostdependency ;-)

Our idea is, when switch A goes down, nagios shouldn't send any alerts
from Server B,C,D which are connected on switch A.

OK, that shouldn't be a problem.

BUT, all of our switches have more than one Network interface, which we
are monitoring.

We have created one host definition for each interface, like this:

[...]
1st interface:
# 'sw-a--if-1' host definition
define host{
        use                     generic-host            ; Name of host
template to use

        host_name               sw-a--if-1
        alias                   sw-a--if-1
        address                 1.2.3.4
        check_command           check-host-alive
        max_check_attempts      3
        notification_interval   0
        notification_period     24x7
        notification_options    d,u,r
        contact_groups          sys-admins
        }

2nd interface:
# 'sw-a--if-2' host definition
define host{
        use                     generic-host            ; Name of host
template to use

        host_name               sw-a--if-2
        alias                   sw-a--if-2
        address                 5.6.7.8
        check_command           check-host-alive
        max_check_attempts      3
        notification_interval   0
        notification_period     24x7
        notification_options    d,u,r
        contact_groups          sys-admins
        }
[...]

We also created a global host definition for all switches which have
more than one interface.

[...]
# 'sw-a' host definition
define host{
        use                     generic-host            ; Name of host
template to use

        host_name               sw-a
        alias                   sw-a
        address                 1.2.3.4
        check_command           check-host-alive
        max_check_attempts      3
        notification_interval   0
        notification_period     24x7
        notification_options    n
        contact_groups          sys-admins
        }
[...]

Our final idea is, to create a "host_group" for each switch witch more
than one interface like:
host_group	sw-a
members		sw-a--if-1,sw-a--if-2

and final, the host_group "sw-a" is the 'host_name' in the
Hostdependency definition.

My question is now, is this possible, if yes, is there any dokumention
available.

Thanks in advance.

Richard
