12.4 Creating a Device Refresh and Removal Schedule

The Device Refresh schedule lets you define how often a device contacts the ZENworks Server to update information such as policies and bundles. The Device Removal schedule lets you take an appropriate action on a device if it has not contacted the ZENworks Server within a certain number of days. This schedule can be defined at three levels:

Management Zone: The schedule is inherited by all device folders and devices. To configure this setting, navigate to Configuration > Device Management > Device Refresh and Removal Schedule.

Device Folder: The schedule is inherited by all devices contained within the folder or its subfolders. Overrides the Management Zone refresh schedule. To configure this setting, navigate to Devices > <Folder (Details)> > Settings > Device Management > Device Refresh and Removal Schedule.

Device: The schedule applies only to the device for which it is configured. Overrides the refresh schedules set at the Management Zone and folder levels. To configure this setting, navigate to Devices > <Select a Device> > Settings> Device Management > Device Refresh and Removal Schedule>

NOTE:The removal schedule can be set on the Management Zone and Device Folder levels only. Also, if you are configuring this setting at a Device Folder or at Device level, then you need to click Override or else the default setting will apply.

12.4.1 Configuring Mobile Device Refresh Schedule

You can configure a manual refresh schedule or a timed refresh schedule.

NOTE:This schedule is not applicable for devices enrolled as ActiveSync Only (Email Only) devices.

Manual Refresh

If you want a device refreshed only when its user manually initiates the refresh, select Manual Refresh, then click Apply. Users can initiate a refresh by clicking the refresh icon located on the ZENworks Agent app on the device or by clicking the refresh icon in the ZENworks End User Portal.

Timed Refresh

This option ensures that for multiple devices that have the same refresh schedule, the ZENworks Server does not initiate their refresh at the same time. The default value is 120 minutes and the minimum value that you need to set is 60 minutes. For example, if you have 1000 devices with the same refresh schedule, you might overburden your ZENworks Server. By selecting this option, the server waits a randomly generated amount of time before initiating the refresh on these devices.

To define the refresh schedule fill in the following fields:

  1. Fill in the following fields to define the schedule:

    Days, Hours, Minutes: Specifies the maximum amount of time within which the mobile devices should refresh. For example, to set the refresh time as 8.5 hours, you would specify 0 Days, 8 Hours, 30 Minutes.

  2. Click Apply to save the settings.

12.4.2 Configuring Mobile Device Removal Schedule

The Mobile Device Lost Schedule panel lets you flag any devices that have not contacted a ZENworks Server within a specified period of time. You can specify the maximum number of days without contact based on which the device is flagged as a lost device.
