Space requirements

For Cisco Option Package (COP) file installation, 100 KB (unzipped volume must be 400 KB for applications).

For log files, 10 MB in the /var/log/active folder path.

CPU and Memory (RAM) Usage: The CCUC service runs with low priority. This helps in restricting the service to minimize CPU usage. The service runs with approximately 488 MB of virtual memory. For more information, see Buffer Size Calculation.

The CCUC service when installed takes about 760 KB of disk space for Voice Operating System (VOS) based products such as, Unified CM and IM&P.

A disk-based buffering is done. The buffering size varies 20–100 MB based on the product and the size of the server deployment.

To know the settings that we recommend, refer to Configure Call Diagnostics section in the Administration Guide for Cisco Unified Communications Manager for your respective Unified CM release at:

Mandatory Cisco Unified Communications Manager Settings:

  • CDR Enabled Flag must be set to True, CDR Log Calls with Zero Duration Flag must be set to True, and Call Diagnostics Enabled flag service parameters must be set to Enabled Only When CDR Enabled Flag is True in all the CUCM nodes in a cluster.

  • Select the Cisco CDR Repository Manager and Cisco CDR Agent radio buttons to enable them in the Cisco Unified Communications Manager. With this setting, UC Analytics in the Control Hub can analyze Call Details Record (CDR) and CMR files.

    Cisco CDR Repository Manager and Cisco CDR Agent are services from the Cisco Unified Serviceability. You can find them at Tools > Control Center - Network Services. Ensure that they're running.

  • The server must be configured for an NTP server. The server time is used in the telemetry data sent to cloud and used for processing. Wrong time can cause the data to be discarded.

  • The Cisco Log Partition Monitoring (LPM) Tool must be running on the Unified CM publisher. This service cleans up CDR and CMR files that are copied to the telemetry service.

If the CDR and LPM services were already running before the telemetry service is installed for the first time, the services are restarted. For subsequent upgrades, the services are not restarted. They may be restarted by the the telemetry service occasionally. Restart of these services does not cause loss of CDR and LPM data.
