Cisco Unified Communication Manager

Cisco Unified Communications (CUCM) is the call-processing component of the Cisco Unified Communications System. It is an IP-based communications system integrating voice, video, data, and mobility products and applications. It enables more effective, secure communications and can transform the way in which we communicate.

VSM and CUCM System health

VSM collects and stores configuration, capacity and availability information relating to the consumption of all essential CUCM resources. This data is mined at all levels, from infrastructure through to the CUCM application layers. It stores this information for reporting, trending and analytical purposes. VSM specifically targets critical areas in CUCM that indicate business-impacting issues.

...

• To enable IT teams to proactively identify potential issues and prevent outages.
• To provide a real time view of overall CUCM health at a glance without having to rely on end-users reporting problems.
• In the event of a service-impacting incident to significantly reduce Mean Time to Repair (MTTR) and therefore to reduce the impact on business operations by quickly identifying the root cause.
