During various processes such as ingestion, archival, backup in the Disaster Recovery Centre, relevant status are continuously monitored using a dedicated component of the Data Management System. In the frame of online and live missions, It is an essential system to follow in real time successive steps of the ingestion/archival flux from the entry point up to the the Disaster Recovery Centre (screenshot on the left shows the daily evolution of such status). It is also used to anticipate problems, looking for example at the throughput used for a service (right screenshot) or to trigger routine actions of tape management in the Data library.
