icontrol equivalent call for 'b node down'

For the monitor_state, you'll want to use the get_monitor_status. You are right that this has 9 possible status values. Basically go with the UP value for a good state and the others either indicate a bad state or that the BIG-IP is in the process of checking it with a monitor.

 

 

For the session_enabled_state, use the get_session_enabled_status method. The get_session_status method has additional information regarding the reason for the new sessions attribute being off.

 

 

And, yes these methods work for PoolMembers as well.

 

 

As for your last question, disabling a node for maintenance, to get the number of current connections, you are going to have to query the staistics with the get_statisics() method and look for the "STATISTIC_SERVER_SIDE_CURRENT_CONNECTIONS" statistic and retry querying the statistics until this value is zero.

 

 

Let me know if this didn't clarify things for you.
