How do you configure ipsla monitor in IOS XR Software, Version 4.2.3?

How do you configure ipsla monitor in IOS XR Software, Version 4.2.3?
We don't see ipsla commands in IOS XR Software, Version 4.2.3. Any other ways to detect ethernet WAN links to trigger HSRP on ASR 9000 series routers? We don't even see track commands.
iphc ipv4 ipv6
tacacs-server tacacs taskgroup tcam
tcp telnet template tftp

Try the following
1. configure
2. track track-name
3. type line-protocol state
4. interface type interface-path-id
5. exit
6. (Optional) delay {up seconds|down seconds}
7. Use one of the following commands:

Please click here for "Implementing Object Tracking on the Cisco ASR 9000 Series Router" . It contains details of the commands available on cli

And then to use the track command in HSRP

hsrp [group-number] track type interface-path-id [priority-decrement]

RP/0/0/CPU0:router(config)# router hsrp
RP/0/0/CPU0:router(config-hsrp)# interface TenGigE 0/2/0/1
RP/0/0/CPU0:router(config-hsrp-if)# hsrp track TenGigE 0/1/0/1
RP/0/0/CPU0:router(config-hsrp-if)# hsrp track TenGigE 0/3/0/1
RP/0/0/CPU0:router(config-hsrp-if)# hsrp preempt
RP/0/0/CPU0:router(config-hsrp-if)# hsrp ipv4

Please click here for "HSRP Commands on Cisco ASR 9000 Series Router"

There were below packages missing in ASR9001 router and hence I could not find track commands. After installing below packages I could see track and ipsla commands.
router hsrp
interface GigabitEthernet0/0/1/0
address-family ipv4
hsrp 1 version 1
address *******
hsrp 2 version 1
priority 110
address *******
track object WAN 15
track WAN
type rtr 1 reachability
operation 1
type icmp echo
destination address *******
frequency 60
schedule operation 1
start-time now
life forever
