- **_MT_SERVICEUUID**: The ID of the service to update with the retrieved monitoring data

- **_MT_SERVICEUUID**: The ID of the service to update with the retrieved monitoring data

- **_MT_CHARACTERISTIC_NAME**: The characteristic of the service with id _MT_SERVICEUUID that will be updated with the retrieved monitoring data

- **_MT_CHARACTERISTIC_NAME**: The characteristic of the service with id _MT_SERVICEUUID that will be updated with the retrieved monitoring data

After filling all the Characteristics, you should be able to see something like the image below:

The above configuration is expected to query ```http://172.16.10.100:9090/api/v1/query?query=gnb_service_state&time=1736528808.484``` every 1 minute and return the result to the service that the user will point out (filling ```_MT_SERVICEUUID	```), and especially into a Characteristic named ```METRICO Result```.

Here, we assume that the user will not provide the ```_MT_SERVICEUUID``` during the Service Order Checkout phase, neither the task's interval (which defaults to 1 hour). Note how the values are filled in with the defaults from the designing phase.

Once the ```_MT_SERVICEUUID``` value is provided, the Metrico RFS will be created and eventually the Service Order will become "COMPLETED", as seen in the Service Order overview.
