Can there be multiple hosts?

Hi!

Doing some work with monitoring scripts and wanted to ask something I've wondered about for some time.

When requesting 

/mgmt/tm/sys/memory
I can see that there are a field for hostId in the response. Could there ever be more than one host, or is this just a matter of formatting in case there ever will be or to keep the syntax the same comparing to tmm?

I could imagine this being used in ie. Viprion systems but I do not have access to any with multiple blades.

In case you do, please go ahead and test with 

curl -sku user:password https://localhost/mgmt/tm/sys/memory
.

Example output to illustrate my meaning:

{
  "kind": "tm:sys:memory:memorystats",
  "selfLink": "https://localhost/mgmt/tm/sys/memory?ver\u003d11.6.1",
  "entries": {
    "https://localhost/mgmt/tm/sys/memory/memory-host": {
      "nestedStats": {
        "entries": {
          "https://localhost/mgmt/tm/sys/memory/memory-host/0": {
            "nestedStats": {
              "entries": {
                "hostId": {
                  "description": "0"
                },

    Well, I have hostId 1 only, and no entry for hostId 0.

    Greetings Patrik, Good guess! This does appear to be Viprion related:

    
 show sys cluster

 show sys host-info | grep Host
Sys::Host: 1
Sys::Host: 2
Sys::Host: 3
