OID for SNMP monitoring line cards in EX9204

Hello,

I need to add the line cards of EX9200 switch for snmp monitoring. Can anyone please tell me what is the proper OID to monitor?

user@switch> show chassis hardware | grep EX9200 
Routing Engine 0 REV 07   750-063458   CAKxxxx          RE-S-EX9200-2X00x6
CB 0             REV 09   750-062852   CAKDxxx          EX9200-SF2
