CUCM as a managed host application
Entuity CUCM improves CUCM performance through management of both the application itself, the CUCM’s managed host, and the network over which it is managing calls. For example, Entuity reports on switch failures, memory utilization, CPU utilization and power supply status, all of which could impact service delivery.
CUCM as a managed host application
Entuity considers CUCMs as applications of managed hosts. Information on these managed host devices can be viewed in Entuity.
Entuity CUCM module allows Entuity to manage CUCM, particularly:
- Cisco Unified Communications Manager Groups
- Date/Time Groups
- Regions
- Device Pools
- Device Defaults
- Enterprise Parameters
- Call Admission Control
- Automated Alternate Routing
- Survivable Remote Site Telephony References
CUCM details
Entuity CUCM details are displayed under Managed Hosts and Applications. Each CUCM managed by Entuity has an entry in the CUCM folder.

CUCM CTI devices
Computer Telephony Integration (CTI) allows leveraging of information systems while making, receiving and managing telephone calls. For example, CTI applications allow:
- retrieval of information from databases derived from caller ID,
- routing of calls to the appropriate customer service representative using information gained through an interactive voice response (IVR) system.

CUCM device pools
Cisco CUCM groups are associated to devices through device pools. Each device belongs to a device pool, and each device pool specifies the Cisco Unified Communications Manager group for all of its devices.
The Device Pools folder lists the device pools on the current CUCM. For each CUCM device pool there is a:
- general tab that outlines the pool’s attributes, including associated CUCM Group and Region.
- device tabs, one for each type of device, i.e. media devices, CTIs, gatekeepers, gateways, phones. These tabs detail all of the devices of that type within the pool. When a particular device type is not in a pool then its tab is not displayed.
CUCM Groups
A CUCM group comprises a prioritized list of up to three CUCMs. The first CUCM in the list serves as the primary CUCM for that group, and the other members of the group serve as secondary (backup) CUCM.
For most systems, you will assign a single CUCM to multiple groups to achieve better load distribution and redundancy.
Device Pool Attributes
Attribute | Description |

Inter-region bandwidths
Regions should only be implemented when there is a requirement to set different bandwidth thresholds for different areas of the network. For example, for CUCM multisite deployments you may require a lower bandwidth limit for individual calls that are sent across a WAN link, than that set for internal calls.
The default voice codec for all calls through CUCM specifies G.711. When only the default codec is implemented, Regions are not necessary.

CUCM processes
Entuity CUCM monitors each process on the CUCM managed host, raising events when any process uses more resources than the set threshold. Also, as CUCM is an application on a managed host, Entuity has visibility into that device’s resources and performance, for example monitoring device disk space, CPU utilization, memory utilization, fans and power supplies.
Process general attributes
Processes General Information tab details the attributes of each process on the CUCM’s managed host.
Attribute | Description |
---|---|
PID | unique process identifier. |
Name | name of the process. |
Process stream attributes
For each process on the CUCM managed host, Entuity monitors CPU and memory usage. Thresholds may be set against these metrics, which when crossed Entuity raises events. Entuity CUCM monitors both CUCM and non-CUCM processes, as it is possible that a problem with CUCM may be caused by another application on the managed host.
For troubleshooting this information can be tracked through the Attribute Grapher. For example, spikes in excess of 80 percent may indicate CUCM cannot manage more functions or is dropping calls. Entuity CUCM allows running of Flex Reports against these metrics, for example maximum and average statistics can provide valuable trending information.
