@DomGarguilo - this changes two endpoints. Let me know if you want any changes in the response object formats and I can make them.

@DomGarguilo - this changes two endpoints. Let me know if you want any changes in the response object formats and I can make them.

I think with these changes the JSON will be something like:

  {
    "type=MANAGER;group=default;address=localhost:9995": [
      { "...": "metric..." },
      { "...": "metric..." }
    ]
  }

That will work but is not quite as nice to parse. I'm thinking it might be better to send a list of objects instead of a map. so something like this:

  [
    {
      "server": {
        "type": "MANAGER",
        "resourceGroup": "default",
        "address": "localhost:9995"
      },
      "metrics": [
        { "...": "metric..." },
        { "...": "metric..." }
      ]
    }
  ]

Not exactly sure what the code will look like but could create something like record ServerIdView(String type, String resourceGroup, String address) for reuse in the other endpoints that need the ServerId too
