In a Central Admin Server Option environment (CASO), alerts generated on a managed media server are automatically rolled up to the central administration server. To see those alerts on the central administration server, you must configure alert categories to enable or disable alerts on each managed media server in the CASO environment, and on the central administration server itself. f you enable Backup Exec alerts on a managed media server without enabling alerts on the central administration server, alerts appear only on the managed media server where they are generated; they will not appear on the central administration server.
