I use ifstated for that. This is my config file:
init-state auto
carp_up = "carp3.link.up && carp10.link.up && carp101.link.up &&
carp100.link.up && carp254.link.up && carp2.link.up && carp7.link.up &&
carp4.link.up"
carp_down = "carp3.link.down && carp10.link.down && carp101.link.down &&
carp100.link.down && carp254.link.down && carp2.link.down &&
carp7.link.down && carp4.link.down"
state auto {
if $carp_up {
set-state primary
}
if $carp_down {
set-state backup
}
}
state primary {
init {
run "/root/scripts/alert_ifstated.sh MASTER"
}
if $carp_down {
set-state backup
}
}
state backup {
init {
run "/root/scripts/alert_ifstated.sh BACKUP"
}
if $carp_up {
set-state primary
}
}
This is the little script "alert_ifstated.sh" too:
#/bin/sh
ifconfig carp | mail -s "[RTR Failover] `hostname` is now $1"
m...@address.me
Hope this helps...

Hi,
Could anyone point me in the right direction on how to have a script
be executed whenever a CARP failover or preempt event occurs?
Need to write a script to send an event message into our monitoring
systems so we can see when a change has occurred.
I haven't used ifstated yet, is this the right tool for this? and if
so could someone throw me an example if you have one?
Thanks, Andy.
