iControl REST Get Pool Member

[JoshBarrow]

I'm currently trying to write a script in powershell that gets the pool members of a specific pool. The problem i'm having right now is that I have it sitting in a different partition than Common and it's throwing " The requested Pool (/Common/pool_name) was not found." which makes sense.

I'm wondering how can I reference the different partition in my powershell script?

$F5 = LTMName

$input = input

$F5PoolURI = "https://$LTMName/mgmt/tm/ltm/pool/$input/members"

$credentials = Get-Credential

$Query = Invoke-RestMethod $LTMPoolURI -Credential $credentials -method GET

I'll give you a trick. Get ie. https://bigip-01.domain.se/mgmt/tm/ltm/pool and check the JSON response.

{
   "items" : [
      {
         "allowNat" : "yes",
         "allowSnat" : "yes",
         "fullPath" : "/rancher/Shared/istio_system_istio_ingressgateway_443",
         "generation" : 1905,
         "ignorePersistedWeight" : "disabled",
         "ipTosToClient" : "pass-through",
         "ipTosToServer" : "pass-through",
         "kind" : "tm:ltm:pool:poolstate",
         "linkQosToClient" : "pass-through",
         "linkQosToServer" : "pass-through",
         "loadBalancingMode" : "round-robin",
         "membersReference" : {
            "isSubcollection" : true,
            "link" : "https://localhost/mgmt/tm/ltm/pool/~rancher~Shared~istio_system_istio_ingressgateway_443/members?ver=16.0.1.1"
         },
         "minActiveMembers" : 1,
         "minUpMembers" : 0,
         "minUpMembersAction" : "failover",
         "minUpMembersChecking" : "disabled",
         "name" : "istio_system_istio_ingressgateway_443",
         "partition" : "rancher",
         "queueDepthLimit" : 0,
         "queueOnConnectionLimit" : "disabled",
         "queueTimeLimit" : 0,
         "reselectTries" : 0,
         "selfLink" : "https://localhost/mgmt/tm/ltm/pool/~rancher~Shared~istio_system_istio_ingressgateway_443?ver=16.0.1.1",
         "serviceDownAction" : "none",
         "slowRampTime" : 10,
         "subPath" : "Shared"
      }
   ],
   "kind" : "tm:ltm:pool:poolcollectionstate",
   "selfLink" : "https://localhost/mgmt/tm/ltm/pool?ver=16.0.1.1"
}

If you look at the self links you can see the correct path there.

TLDR;

Replace "/" in the path with ~. So if you want to see the members in /rancher/istio_system_istio_ingressgateway_443 you can just use the URI /mgmt/tm/ltm/pool/~rancher~Shared~istio_system_istio_ingressgateway_443/members

Make sense?

I wrote a guide for the REST API and there's some Powershell examples in it. Maybe it'll help too?
