We're using ifstated to send nagios passive alerts in case a lagg or
carp's interface's state should become degraded.
Find below the config we're using:
carp_up = "carp410.link.up && carp13.link.up"
carp_down = "carp410.link.down && carp13.link.down"
carp_unknown = "carp410.link.unknown || carp13.link.unknown"
init-state auto
state auto {
set-state inconnu
if $carp_up {
set-state primary
}
if $carp_down {
set-state backup
}

set-state inconnu
}
}
state primary {
