Can't get Global LB Pool Member Availability

I'm trying to modify the Powershell code in the codeshare https://devcentral.f5.com/wiki/icontrol.powershellpoolmemberavailability.ashx to pull GTM Pool Member availability. When I switch out the LocalLBPoolmember property to GlobalLBPoolMember, I get an error "cannot find an overload for get_object_status".

What am I missing?

availability
BIG-IP DNS
devops
iControl
management

    I find that it is usually easiest to get the data from the F5 itself. I'll use each control until I build up a full set of data.

     

    Sorry for the psudocode, but it looks like

     

    pools = GlobalLB.get_pools()

     

    pool_members = GlobalLB.get_pool_members(pools)

     

    pool_member_status = GlobalLB.get_pool_member_status(pools, pool_members)

    @Brent West - Thanks for the info! Now my problem seems to be in how I provide the pool member... I try to build the {[IP],[PORT]} manually as an iControl.CommonIPPortDefinition and pass it in, but I still can't seem to get it to line up. ` $tmp = New-object iControl.CommonIPPortDefinition $tmp.address = $pool[0].address $tmp.port = $pool[0].port ` I've also tried pulling the members raw into the tmp variable... ` $tmp = (Get-F5.iControl).GlobalLBPool.get_member((,$Pool)); ` So that I could address the nodes individually...neither seem to work as I get the same results. ` PS C:> (Get-F5.iControl).GlobalLBPoolMember.get_object_status(($pool,$tmp[0].member[0])) Cannot find an overload for "get_object_status" and the argument count: "1". At line:1 char:1 + (Get-F5.iControl).GlobalLBPoolMember.get_object_status(($pool,$tmp[0].member[0]) ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodException + FullyQualifiedErrorId : MethodCountCouldNotFindBest `

      Thank you very much! Here's the final code block I put together based on your recommendations... 
      ForEach ($pool in $pools){
$ht = [ordered]@{}
$poolmembers = (Get-F5.iControl).GlobalLBPool.get_member($pool)
ForEach ($member in $poolmembers.member){
$memberstatus = (Get-F5.iControl).GlobalLBPoolMember.get_object_status($pool,$member)
$ht.pool = $pool
$ht.member_ip = $member.address.tostring()
$ht.member_name = [System.Net.Dns]::GetHostEntry($member.address.tostring()).HostName
$ht.port = $member.port
$ht.availability_status = $memberstatus.status.availability_status
$ht.enabled_status = $memberstatus.status.enabled_status
$ht.status_description = $memberstatus.status.status_description
$tmp = New-Object PSObject -Property $ht
$table += $tmp
}
}
