LB::status
       Returns the status of a node address or pool member.

SYNOPSIS
       LB::status (LB_STATUS)?

       LB::status node IP_ADDR (LB_STATUS)?

       LB::status pool POOL_OBJ member IP_ADDR PORT (LB_STATUS)?

DESCRIPTION
       Returns the status of a node address or pool member. Possible status values are up, down, session_enabled, and
       session_disabled. If you supply no arguments, returns the status of the currently-selected pool member.	Syntax:
	   LB::status
	   LB::status node 

	   LB::status pool  member  
	   LB::status 
	   LB::status node 
 
	   LB::status pool  member 
  

       Slight difference for GTM syntax, rather than node, use vs:
	   LB::status vs  
	   LB::status vs   

RETURN VALUE
       LB::status
	   Returns the status of the currently-selected node (after LB_SELECTED event only). Possible values are: up | down |
       session_enabled | session_disabled

       LB::status node 
	   Returns the status of the node with the specified IP address. Possible values are: up | down | session_enabled |
       session_disabled

       LB::status pool  member  X
	   Returns the status of the specified pool member. Possible values are: up | down | session_enabled | session_disabled

       LB::status X
	   Returns TRUE if the status of the currently-selected node matches the specified status argument.

       LB::status node 
 X
	   Returns TRUE if the status of the specified node matches the specified status argument.

       LB::status pool  member 
  X
	   Returns TRUE if the status of the specified pool member matches the specified argument. (This syntax doesn't seem to be
       working as expected in 9.2.3 at least... use alternate syntax in Example below)
