Cisco CDR Insert reads transferred files, places contents into the call detail record (CDR) database, and removes old files. When you enable CDR collection, Cisco CallManager writes CDRs to flat files on the subscriber hard drive as calls are made. The Cisco CDR Insert service periodically inserts the records from these files into the publisher centralized SQL database. The Cisco CDR Insert service does not insert a record if the CDRFormat enterprise parameter has a value of Flat. For more information on CDRs and related parameters
Requirements and Recommendations
Cisco CDR Insert service requires the Cisco Database Layer Monitor service.
Limit the number of nodes that are configured with Cisco CDR Insert service.
Cisco CDR Insert must reside on the same server as the CDR database, which is the publisher server.
Call Detail Records
When CDR collection is enabled through the CDR Enabled Flag Cisco CallManager service parameter, Cisco CallManager writes call detail records (CDRs) to flat files on the subscriber servers as calls are completed. When CDR Diagnostic collection is enabled through the Call Diagnostics Enabled Cisco CallManager service parameter, Cisco CallManager writes call detail diagnostic records to flat files on the subscriber servers as calls are completed. The Cisco Database Layer Monitor service periodically moves the CDR files from the subscriber to the publisher server (or configured server), and the Cisco CDR Insert Service inserts the records into the configured CDR database.
Note The Cisco CDR Insert service does not insert a record if the CDR Format enterprise parameter has a value of `CDR will be kept in flat files.' If the service is disabled, Cisco CDR Insert does not delete the CDR files.
Enable and configure CDR collection through service and enterprise parameters that are set in Cisco CallManager Administration. You must enable CDR collection on each Cisco CallManager in the cluster for which you want to generate records
CDR-Related Service and Enterprise Parameters
The following service parameters apply to CDRs:
Max CDR Records - Cisco Database Layer Monitor service parameter that controls the maximum number of CDRs on the system. When this limit is exceeded, the oldest CDRs automatically get removed, along with the related CMR records, once a day. The default specifies 1.5 million records.
CDR Enabled Flag - Cisco CallManager service parameter that controls whether CDRs are generated. Set this parameter on each Cisco CallManager in the cluster. You do not need to restart the Cisco CallManager for the change to take effect.
CDR Log Calls With Zero Duration Flag - Cisco CallManager service parameter that controls whether calls with zero duration are logged in CDRs. The default specifies False (zero duration calls not logged).
Call Diagnostics Enabled - Cisco CallManager service parameter that controls whether call diagnostic records containing QoS information about calls are generated. The default specifies False (diagnostics not generated).
