I have enabled the prometheus plugin via Konga. The current raw view on the plugin views as:

```auto
{
  "enabled": true,
  "name": "prometheus",
  "config": {
    "per_consumer": false
  },
  "tags": null,
  "protocols": [
    "grpc",
    "grpcs",
    "http",
    "https"
  ],
  "created_at": 1664572654,
  "route": null,
  "id": "279affe4-e7ca-4b9a-87ef-fa1e9c26af06",
  "consumer": null,
  "service": null
}

```

The [configuration reference](https://docs.konghq.com/hub/kong-inc/prometheus/) details how there are additional options that can be enabled.

I’ve tried permutations of something like including:

```auto
curl -X PUT http://localhost:8001/plugins/279affe4-e7ca-4b9a-87ef-fa1e9c26af06 --data "name=prometheus" --data "config.bandwidth_metrics=true"

```

but I get:

```auto
{"message":"schema violation (config.bandwidth_metrics: unknown field)","fields":{"config":{"bandwidth_metrics":"unknown field"}},"name":"schema violation","code":2}

```

as a return error.

I’ve not used the API too much - I’ve been too reliant on Konga. Any tips/suggestions would be appreciated.
