cisco asa5505 multiple SLA Monitors?

I have several branch locations each with an ASA5505 connected to a cable modem.

The ASA's have a VPN tunnel configure to the main location.

I would like to have several SLA's configured to monitor several different hops for the purpose of emailing me when any monitored hop drops.  There is no alternate route I can use, so if an SLA trips, I will just get an email alert - no other action needs to be taken by the ASA.

For example, if I run a traceroute from Location-A to the main office, I would like to have an SLA on the cable modem (i.e., the ASA's default route IP), hop #3 in the trace (someplace in the ISP network), and finally to the endpoint of the tunnel (Main Location).

Visually:

I am confused by how to track the 2nd and 3rd SLA monitor.

e.g.

route outside 0.0.0.0 0.0.0.0 66.xx.yy.97 track 1

sla monitor 10
  type echo .. 66.xx.yy.97
sla monitor schedule 10 life forever....

sla monitor 20
  type echo .. 209.xx.yy.114
sla monitor schedule 20 life forever....

sla monitor 30
  type echo .. 38.aa.bb.82
sla monitor schedule 20 life forever....


track 1 rtr 10 reachability

track 2 rtr 20 reachability

track 3 rtr 30 reachability

What you can do is send an email for syslog 622001.
 
http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/monitor.html#wp1064823 explains how to send emails for a syslog. Here is a sample
 
logging mail high-priority
logging list sla-list 622001
logging mail sla-list


logging from-address email_address
logging from-address asaxxx@example.com
smtp-server ip_address

I am already logging the 622001 messages - as shown in OP.

My question then, is do I have to actually have something assigned to the "track [n] rtr [m] reachability", like a "route outside 0.0.0.0 0.0.0.0 xx.yy.zz.aa [n] track [n]"

(where "n" is the metric and the track id).

Thanks.

Not sure if this is correct, but for my purposes it is working.

I am tracking a route in the SLA with a *higher* metric than the default route.

route outside 0.0.0.0 0.0.0.0 <ISP> 1
route outside 0.0.0.0 0.0.0.0 <ISP> 2 track 1
route outside 0.0.0.0 0.0.0.0 <isp> 3 track 2



This way, I get the alert, but since there is no failover ISP connection, the default route is not removed, and I get the alert if any of the upstream hops becomes unreachable.
