There's a even beter way, I think.
Look at the outout below
The State column actually tells you excatly what that node state is at that moment.
node0:
--------------------------------------------------------------------------
Session ID: XXXX, Policy name: lnx/7, State: Backup, Timeout: 704, Valid
In: XX.XX.XX.XX/22016 --> XX.XX.XX.XX/2222;tcp, If: reth0.0, Pkts: 0, Bytes: 0
Out: XX.XX.XX.XX/22 --> XX.XX.XX.XX/22016;tcp, If: reth1.0, Pkts: 0, Bytes: 0
node1:
--------------------------------------------------------------------------
Session ID: XXXX, Policy name: lnx/7, State: Active, Timeout: 1776, Valid
In: XX.XX.XX.XX/22016 --> XX.XX.XX.XX/2222;tcp, If: reth0.0, Pkts: 982806, Bytes: 45557515
Out: XX.XX.XX.XX/22 --> XX.XX.XX.XX/22016;tcp, If: reth1.0, Pkts: 1763618, Bytes: 2482431535
