  "port": postgres_port,
  "user": "datasentinel",
  "password": "myPassword",
  "tags": "application=application_name,environment=application_type,datacenter=datacenter"

Replace **MyConnectionName** with a meaningful connection name in your environment.
{% endhint %}

{% code title="Example with the agent CLI" %}

```bash
datasentinel add connection myConnectionName -f myInstance.json
```

{% endcode %}

{% hint style="info" %}
A script is present in the **datasentinel** subdirectory as an example named **connection\_example.sh**

The tags are customizable, allowing you to define your own tags.\
They are extremely useful in the user interface for filtering, grouping data, and defining role-based access.
