# Scan Devices

With Mobile Device Manager Plus, you can scan managed devices and/or set up scheduled scans in order to obtain granular details of the managed devices. To ensure that the device remains in contact with the MDM server, it is recommended to schedule frequent device scans. This is so that the devices stay in contact with the server. Device summary, Network summary, OS summary and various other details about the devices can be fetched. The steps involved in performing and scheduling device scans are mentioned below.

1. On the web console, navigate to the **Inventory** tab click on **Scan Devices.**
2. Under **Device Name**, Select the Devices that need to be scanned and click on the **Scan Devices** button. To scan all the enrolled devices, click on the **Scan All** button.

The Scan process is initiated and the result of the scan is shown under **Scan Status,** along with the details shown under **Remarks.**

## Schedule Device Scan

The following steps explain how to schedule the scan at customized intervals.

1. On the web console, go to **Inventory** > **Schedule Device Scan** and click on **Schedule Now**
2. Customize your schedule by clicking on Daily/Weekly/Monthly, providing a date and time and other details.
3. Click on **Save Changes** to save the configuration.

You can see the following status when a device is being scanned.

If the scan has been completed, the last contact time is also updated on the server.

## Last Contact Time

**Last Contact Time** is the most recent timestamp at which a managed device communicated with the MDM server. It indicates whether a device is active and reachable.

### How it is Calculated

The server updates this timestamp whenever the device:

- Completes a device scan (manual or scheduled).
- Checks in during a routine sync.

### Where to View

Navigate to **Inventory** > **Scan Devices**. The **Last Contact Time** column displays the most recent communication timestamp for each managed device. You can use the **column chooser** icon at the top-right of the table to customize the columns shown.

The **Last Contact Time** can also be viewed under the **Inventory** > **Devices** view.
