Why are some fields not visible when registering a service in Consul?

Question

System administration

There is a grafana.json file with a description of the service

{
  "Name": "Grafana",
  "Address": "10.233.87.165",
  "Port": 5325
}

Registering a service

curl -XPUT -d @grafana.json 127.0.0.1:8500/v1/agent/service/register

Get service description
