/mcpmore than 31 for monthly), the chart displays all the days (with 0 value for the days that do not generate records). A table displays for all the days with relevant value and 0.00 for the days that do not contain data. • When records generate (for at least one day in the chosen date range) and the number of days that is chosen is less than the number of days that the report can show (less than 7 for weekly and less than 31 for monthly), the chart displays all the days (with 0 value for the days that do not generate records). A table displays all the days with relevant value and 0.00 for the days that do not contain data. In all the CAR reports that display the username, userid displays if CAR cannot retrieve the username. This situation can occur when the report gets generated for prior data where the user that was involved in a call then no longer exists in the system (Unified Communications Manager database). Generated Report Schedule Automatically generating reports comprises a two-step process. First, you must enable the reports that you want to have generated. Second, you must schedule the reports for the day and time that you want them to generate. CAR provides a default schedule, so if the default schedule is acceptable, you need only enable the reports that you want to automatically generate. Reports and email alerts do not automatically get enabled on a new installation. You must enable the reports that you want to automatically generate. To enable or disable a report generation, see the Enable Automatic Generation Reports, on page 57 for instructions on how to generate reports and emails automatically. To change the specific time each day, week, or month that reports get generated and get purged from the system, see Set Up CDR Load Schedule, on page 36. Audit Logging With audit logging, any configuration change to the Unified Communications Manager system gets logged in separate log files for auditing. An audit event is any event that is required to be logged. Cisco Unified CDR Analysis and Reporting create audit logs for these events: • Scheduling the CDR Loader. • Scheduling the daily, weekly, and monthly user reports, system reports, and device reports. • Mail parameters configurations. • Dial plan configurations. • Gateway configurations. • System preferences configurations. • Autopurge configurations. • Rating engine configurations for the duration, time of day, and voice quality. • QoS configurations. • Automatic generation/alert of pre-generated reports configurations. • Notification limits configurations.
