CDR AGENT
Runs as a network service on every node in a cluster (including the Publisher).It polls the local directory for CDR, CMR flat files every 6 seconds.If finds new CDR, CMR flat files, it pushes CDR, CMR flat files from that node to the CDR Repository node (Publisher).Upon successful transfer, the system deletes the local copy of the file.
CDR REPOSITORY MANAGER
It runs as a Network Service on all nodes in a cluster. But, in reality only the CDR Repository Manager on the Publisher performs any actions. On all other nodes, the service simply starts up, but then goes to sleep.
It creates the directory structure used by CAR services.
It manages the flat files that are received from other nodes. When the file arrives on the CDR Repository node, the CDR Repository Manager detects it.The system archives the file in a directory that is dedicated to the date that is indicated by the timestamp that was placed in the file name when the file was created.
Sends CDR files up to three outside billing servers.
Maintains CDR files for a certain number of days, up to 30 days.
Periodically check the disk usage and delete old files. The thresholds are configured using the CDR Management (covered later in the presentation).Generate alarm if delivery failed, or disk usage too high.
