DMP Group Memberships
Each DMP considers its group memberships when it starts to receive provisioned data from DMS-CD.
•DMPs that are assigned to only one DMP group apiece accept provisioned data to the best of
their capacity.
•DMPs that belong to multiple groups, which are scheduled to receive differing deployments
simultaneously, can receive only one of these deployments at a time. When they are the target of
simultaneous deployments, DMPs generate a queue for themselves and receive the various
deployment packages one at a time. Depending on the size and relative importance of one package
over another, such DMPs might sometimes lack assets that you planned for them to have.
Tip You might notice after a DMP joins multiple groups that it runs out of local storage space (on usb_1 or usb_2) faster
than it did before.
•You can use the Play Now feature to deploy an empty playlist to any DMPs whose local storage has kept copies of obsoleted
assets. This method clears local storage quickly.
•Alternatively, when local storage contains a combination of assets—some needed, others not —you can create and deploy
a playlist that includes only the useful assets. The DMPs that receive this deployment will keep what they need and delete
everything else.
Understand Shared Scheduling Features for Deployments
Because DMS-CD uses the same scheduling features that are built into Cisco Digital Signs, you can
schedule assets to be provisioned late at night or at other convenient, planned times. Furthermore,
reporting features in Cisco Digital Signs show you which DMS-CD deployments have succeeded or
failed and show you which files were deployed to each DMP.
Understand DMS-CD Alert Reports
•Monitoring Modes, page 19-6
•Error Conditions, page 19-6
•Alert Types, page19-7

Monitoring Modes

The Alert Reports feature supports modes that you can use when checking for DMS-CD
deployment errors.
•Live monitor mode describes the most recent 100 instances of an event type that you choose. Its data
is refreshed automatically every 90 seconds.
•Snapshot mode describes only the events that match the combination of all parameters that
you choose.

Error Conditions

DMS-CD logging captures, detects, and reports these error conditions.
•DMS-CD cannot retrieve a file.
•DMS-CD cannot provision a file (DMP out of space or missing USB)
•DMP is not reachable (is down, or has wrong IP)
