Use this information to learn about the supported products, supported Unified CM, IM & Presence releases, and recommended configurations for Webex Cloud-Connected UC on-premises devices.
The following products support CCUC Analytics service:
Cisco Unified Communications Manager
Cisco Unified Communications Manager IM & Presence Service
The supported Unified CM releases are:
Unified CM 11.5(x)
Unified CM 12.0(x)
Unified CM 12.5(x)
Unified CM 14.0(x)
To know the endpoints that are supported by CCUC, see Cisco Endpoints Supported on Unified CM releases.
For information about organization account roles and entitlements, see Assign Organization Account Roles in Cisco Webex Control Hub.
The space requirement for telemetry service is 3 MB for executables.
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 345 MB of RAM. The CPU usage is 12%. For more information, see Buffer Size Calculation.
The CCUC service when installed takes about 155 MB of disk space for Voice Operating System (VOS) based products such as, Unified CM and IM & Presence.
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 or to Enabled Regardless of CDR Enabled Flag in all the Unified CM nodes in a cluster.
Ensure that the Cisco CDR Repository Manager network service is running on all publisher nodes and the Cisco CDR Agent network service is running on all nodes in the Unified CM clusters. 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 network services from the Cisco Unified Serviceability. You can find them at . 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. This service is available fromon the Cisco Unified Serviceability page in Cisco Unified Serviceability.
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 telemetry service occasionally. Restart of these services does not cause loss of CDR and LPM data.
