# Monitoring devices

Device monitoring allows you to view devices which are connected to the Farm or have established a connection at least once in the past. To monitor devices, select the **Device Manager** category in the Parallels RAS Console and click the **Devices manager** tab in the right pane. The information for a device includes:

* Device name
* IP address
* State (see below for the list of states)
* Last user (who used a device)
* MAC address
* OS version
* Parallels Client version
* Group (if a device is a member of a device group)
* Gateway name (the RAS Secure Gateway a device is connected to)
* Gateway IP address

### Device states

Devices that connect to Parallels RAS can have any of the following states:

* **Off**: Device is switched off.
* **Connected**: Device is connected.
* **Logged On**: Devices is logged on to the system.
* **Standalone**: Device has previously connected to the Parallels RAS but is not using Parallels Client, therefore it cannot be managed.
* **Not Support**: Device is not supported by the Parallels RAS.
* **Foreign Managed**: Connecting to the Farm but managed by a different Farm.
* **Not Manageable**: Client not manageable due to incompatible client version or uninstalled component.
* **Locked**. Device has an active session in locked status.
* **Pair Pending**. Connection should be refreshed on the client side; port UDP 20009 is blocked from the client to gateway; client management port is disabled on the gateway.

### Switching off device monitoring

If you use third-party endpoint management solutions and do not need Parallels RAS device monitoring, you can switch it off on the **Device Manager** > **Options** tab. It helps you to save computing resources and may improve performance of the RAS Console.

To switch off device monitoring:

1. In the RAS Console, navigate to **Device Manage**r > **Options**.
2. Clear the **Enable device manager** option.
3. Click **Yes** and **Apply**.

As soon as you switch off device monitoring, the RAS Console stops tracking connected devices and deletes device connection history, which is displayed on the **Device Manager** > **Device Manager** tab. After that you can still view information about current connections in the **Sessions** category.
