Monitoring and Maintaining the Digital Media Player
Series 2 DMPs: DMP-2K and SV-4K
Series 3 DMPs: CV-HD and CV-UHD
Series 4 DMPs: CV-HD2 and CV-UHD2
This module describes the workflow and tasks to monitor and maintain the working operation of the digital media player. It is intended for Cisco Vision Dynamic Signage Director administrators and installers.
For more information, see also the Release 6.3: Cisco Vision Dynamic Signage Director Operations Guide.
This module includes the following topics:
■ Performing a Regular Reboot of the Digital Media Players
■ Verifying Digital Media Player Compliance
■ Clearing the Storage on the Digital Media Player
■ Clearing Registries on the Digital Media Player by Restoring Factory Defaults
Performing a Regular Reboot of the Digital Media Players
Perform a regular reboot of the devices to maintain normal operation of the digital media players. We recommend a weekly reboot.
For information about how to configure the Reboot DMP system task, see the Task Note: Configure Reboot DMPs.
Note: The reboot task applies globally to all media player devices. It is not enabled by default.
Verifying Digital Media Player Compliance
Cisco Vision Director allows you to compare values on the DMP device against required values configured in the Cisco Vision Dynamic Signage Director DMP settings.
Figure 1 shows how a DMP device should appear when it is fully compliant with the configured Cisco Vision Dynamic Signage Director settings:
■Required Value—Value configured in Cisco Vision Dynamic Signage Director, or automatically set by the system.
■Value on Device—Setting that the DMP device is running.
Figure 1 Normal Compliance for a DMP Device
Table 1 DMP Compliance Property Descriptions
Property Name |
Description |
|
Enables ability to access the DMPs Diagnostic Web Server.1
|
|
Value is always “on.” Static IP addresses are not supported.
|
|
NTP client service on the DMP device. Value is always “yes.”
|
|
(Release 4.1 and Later) SNMP agent service on the
Series 2 and Series 3 device. Default value is no.
|
|
|
|
Name of the NTP server for the DMP. For PTP secondaries, setting the time via NTP is disabled on DMP.
|
|
Interval (in seconds) after which the PTP leader synchronizes its time with the NTP host.
|
|
|
|
Switch VLAN reported by LLDP for the DMP.
“$svd_ignore” setting in Dynamic Signage Director means that the value is not used for compliance verification.
|
|
This corresponds to the global DMP setting “Force IGMPv2” (under Networking).
|
1. The global DMP setting “Enable DWS” (under Networking) should match what the DMP reports. It is possible for a DMP to report a value different from the registry key. This can happen when DWS is enabled or disabled via DMP Command.
To verify digital media player compliance:
1. Click Device Management.
2. In the Selected Devices panel, select all DMPs about which you want an updated status. The lower Status pane appears.
3. Click the Compliance tab.
Clearing the Storage on the Digital Media Player
The DMP devices have different sizes of local storage:
■The CV-HD2 DMPs have 128 GB of storage with approximately 100 GB available for content.
■The CV-UHD2 DMPs have 128 GB of solid-state storage with approximately 100 GB available for content.
■The SV-4K and Series 3 DMPs have 120 GB of solid-state storage with approximately 100 GB available for content.
■The DMP-2K DMPs have 64 GB of solid-state storage with approximately 53 GB available for content.
If you are running out of storage or need to recover the SSD, clear the storage on the media player.
To find information about available storage:
1. Select a DMP device in the Device Dashboard device list.
2. Click the Settings tab > Storage in the device details area of the dashboard.
Note: The HTML runtime must be running on the digital media player to use this task.
You also can find information about available storage if you view device details from thumbnail view in Device Management (CCM).
To clear the storage on the digital media player:
1. Click Device Management.
2. Select the DMP devices that you want to clear.
3. Use the drop-down arrow to select Reset Storage (Figure 2).
Figure 2 Reset Storage Command
4. Click Send Command.
The contents of the SSD storage is removed (including the Cisco Vision Dynamic Signage Director runtime software and script contents) on the devices. The devices will not automatically reboot after this command.
5. Use the drop-down arrow to select Reboot Device (Figure 2).
6. Click Send Command.
The selected devices reboot and re-provision firmware and settings.
Clearing Registries on the Digital Media Player by Restoring Factory Defaults
To clear the registries on the digital media player:
1. Click Device Management.
2. Select the devices that you want to clear.
3. Use the drop-down arrow to select Restore Default Settings (Figure 2).
4. Click Send Command.
5. Any persistent device settings on the DMP s are erased and the box will be in factory default state. The DMP automatically reboots and re-provisions its firmware and settings.
