Why SLA monitor failed ?

I have VPN tunnel setup between two location and every night here and here tunnel goes down may be because not enough interesting traffic in night time. so i am thinking to setup sla monitor to generate interesting traffic, this is what i am doing

Local LAN: 10.0.10.0/24

Remote LAN: 10.30.0.0/24

Life is good, i can ping remote LAN ip.

Local_ASA (config)# ping inside 10.30.0.10

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.30.0.10, timeout is 2 seconds:

!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 10/16/20 ms

This is my SLA monitor config:

sla monitor 2

type echo protocol ipIcmpEcho 10.30.0.10 interface inside

num-packets 3

sla monitor schedule 2 life forever start-time now

Look like it doesn't like and it failed to ping.. WHY ?

Local_ASA (config)# show sla monitor operational-state 2
