# Adapter degraded status

> How to implement and recognize the degraded connection state for adapters in Itential Platform.

## Degraded connection

The `degraded` status is an additional adapter state alongside the `online` (connected) and `offline` (disconnected) statuses. This state is intended for adapters like adapter-nso and others that have multiple connection types.

Some scenarios where the degraded state applies include:

* The connection is not fully up or fully down.
* One method of communication for an adapter has been disconnected, but another is still active.
* The adapter is connected, but with an unstable connection.
* Some functions related to a mode of communication fail to respond.

## Emit degraded events

Add the following code to instances where you would like to send the adapter to the degraded state:

```javascript
this.emit("DEGRADED", {
    reason: 'Reason adapter is degraded (will appear on system page)'
});
```

Add the following code to instances where the adapter is no longer degraded and the state should be removed — for example, if a second method of communication comes back online, the connection stabilizes, or a specific call succeeds:

```javascript
this.emit("FIXED", {
    reason: 'Optional'
});
```

## Recognize a degraded adapter in Admin Essentials

#### Start Itential Platform and Adapter NSO

Start both Itential Platform and Adapter NSO.

#### Connect with default credentials

Connect them using the default `admin` username and `admin` password.

#### Verify initial connection status

Check the connection status from **Admin Essentials** → **Profiles** → **Adapters**. Status should show as "Running" and connection as "Online".

#### Create a new user in NSO

Create a new user in NSO with the name `client`.

#### Update adapter credentials

Change the Adapter NSO properties credentials to the newly created user (username and password).

#### Verify updated connection status

Go back and check the connection status from **Admin Essentials** → **Profiles** → **Adapters**. Status should show as "Running" and connection as "Online".

#### Delete the client user from NSO

Go to NSO and delete the `client` user.

#### Confirm degraded status

Check the connection status from **Admin Essentials** → **Profiles** → **Adapters**. Status should now show as "Running" and connection as "Degraded".
