# Creating and Tracking a Metric

We’d like to see how much potion our Heroes have left, we can easily specify a gauge indicator alongside our assets.

### Create and Track a Metric

#### **Add Gauge to Hero Asset**

```
PUT api.skyledge.com/controlrooms/{controlRoomId}/asset-types/{assetTypeId}

{  
   "displaySettings":{  
      "MAP":[  
         {  
            "tagName":"slc-gauge",
            "options":{  
               "metric":"remainingPower",
               "unhealthy":"remainingPower <= 10"
            }
         }
      ]
   }
}

```

{% tabs %}
{% tab title="cURL" %}

```
curl --location --request POST 'https://api.skyledge.com/asset-types/ASSET_TYPE_ID/assets' \
--header 'X-Authorization: API_KEY' \
--header 'Content-Type: application/json' \
--data-raw '{  
   "displaySettings":{  
      "MAP":[  
         {  
            "tagName":"slc-gauge",
            "options":{  
               "metric":"remainingPower",
               "unhealthy":"remainingPower <= 10"
            }
         }
      ]
   }
}'
```

{% endtab %}

{% tab title="NodeJs" %}

```
import { Configuration, AssetRequest, AssetsApi } from '@skyledge/sdk';

const configuration = new Configuration({
  apiKey: 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX',
  basePath: 'https://api.skyledge.com',
});

const data: AssetRequest = {
  displaySettings: {
    MAP: [
      {
        tagName: 'slc-gauge',
        options: {
          metric: 'remainingPower',
          unhealthy: 'remainingPower <= 10',
        },
      },
    ],
  },
} as any;

const assetIdentifier = ASSET_IDENTIFIER;

const assetApi = new AssetsApi(configuration);

const addMetric2Asset = await assetApi.updateAssetUsingAssetIdentifier(
  assetIdentifier,
  data,
);

console.log(addMetric2Asset.status);

```

{% endtab %}

{% tab title="Python" %}

```
import requests
import json

url = "https://api.skyledge.com/asset-types/ASSET_TYPE_ID/assets"

payload = json.dumps({
  "displaySettings": {
    "MAP": [
      {
        "tagName": "slc-gauge",
        "options": {
          "metric": "remainingPower",
          "unhealthy": "remainingPower <= 10"
        }
      }
    ]
  }
})
headers = {
  'X-Authorization': 'API_KEY',
  'Content-Type': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)

print(response.text)

```

{% endtab %}
{% endtabs %}

Notice that remainingPower refers to the metric we specified in Step 5. We can also create rules to indicate when the gauge indicator should enter an “unhealthy” warning state.
