Confusion on changing a pool member state

I have tried all the variations you gave above plus some alterations of it. I get the following.

I know that the argument expects two arguments since if I pass 1 or 3 it fails asking for two. So I tried the following examples

member = {:port=>0, :address=>"172.16.20.65"}
monitor_state = "STATE_DISABLE"
@ltm["LocalLB.PoolMember"].set_monitor_state(@poolname, [member, monitor_state])
@ltm["LocalLB.PoolMember"].set_monitor_state([@poolname], [member, monitor_state])
@ltm["LocalLB.PoolMember"].set_monitor_state(@poolname, [[member], [monitor_state]])

I get the same error on all of them

The API asks for a struct so I took it to the next extreme via the following.

Struct.new("Member", :address, :port)
Struct.new("Member_status", :member, :status)
m = Struct::Member.new("172.16.20.65", 0)
ms = Struct::Member_status.new(m, 0)

@ltm["LocalLB.PoolMember"].set_monitor_state(@poolname, ms)

API Says it expects a MemberMonitorState which is a struct of IpPortDefinition and EnabledState. IpPortDefinition is a struct of a string, Address, and long, port. The EnabledState looks like simply a 0 or 1.

Anyhow I get the same errors
