I'm using IP SLA to track and monitor on IP of internet.
SO, WAN IP of the router is 1.1.1.1
IP of ISP: 1.1.1.2
But i want to monitor some other internet ip, different from the one of ISP (3.3.3.3)
i've created this configuration:
i've a default route like this:
ASA01(config)#track 10 rtr 10 reachability
ASA01(config-track)#exit
ASA01(config)#ip sla 10
ASA01(config-ip-sla)#icmp-echo 3.3.3.3
ASA01(config-ip-sla-echo)#timeout 1000
ASA01(config-ip-sla-echo)#threshold 2000
ASA01(config-ip-sla-echo)#frequency 3
ASA01(config-ip-sla-echo)#exit
ASA01(config)#ip sla schedule 10 life forever start-time now
ASA01(config)#ip route 0.0.0.0 0.0.0.0 1.1.1.2 track 10
SO in this way, the tracking status remains down.
Have i to create another static router to monitorin ip 3.3.3.3, something like this:
ASA01(config)#ip route 3.3.3.3 1.1.1.2???
Regards!

my understanding is the default route in your post will not be installed cause default route will only be intalled if firewall get ping reply from 3.3.3.3 but you can't ping 3.3.3.3 without a default route installed, unless you have another default route, which is normal installation when you are trying to use sla monitor. like:
ip route 0.0.0.0 0.0.0.0 a.b.c.d 250
ip route 0.0.0.0 0.0.0.0 1.1.1.2 track 10

so, on my suggestion, is it needed that i've to add another ip static route to reach the ip i want to monitor, right?

sure you could do that (if you have only one internet link) and it will work while it just doesn't make sense. so the configure will looks like:
ip route 3.3.3.3 255.255.255.255 1.1.1.2
ip route 0.0.0.0 0.0.0.0 1.1.1.2 track 10
