This chapter provides an overview of Cisco CallManager objects and counters, and the real-time information monitoring applications that Cisco CallManager supports. The following sections provide information about Cisco CallManager objects and counters, and monitoring applications, and how Cisco CallManager uses them:

Microsoft Performance Objects and Counters

Cisco CallManager directly updates Microsoft Performance counters (called perfmon counters), which are call-processing-related counters. The counters contain simple, useful counts such as number of registered phones, number of active calls, and number of available conference bridge resources.

The following list identifies the Cisco CallManager perfmon objects (objects contain the counters):

•Cisco Analog Access

•Cisco CallManager

•Cisco CallManager Attendant Console

•Cisco CallManager System Performance

•Cisco CtiManager

•Cisco GateKeeper

•Cisco H323

•Cisco HW Conference Bridge Device

•Cisco Lines

•Cisco Locations

•Cisco Media Streaming App

•Cisco Media Termination Point

•Cisco Messaging Interface

•Cisco MGCP FXO Device

•Cisco MGCP FXS Device

•Cisco MGCP Gateways

•Cisco MGCP PRI Device

•Cisco MGCP T1CAS Device

•Cisco MOH Device

•Cisco MTP Device

•Cisco Music On Hold Server

•Cisco Phones

•Cisco SW Conference Bridge

•Cisco SW Conference Bridge Device

•Cisco Tftp

•Cisco Transcode Device

•Cisco EM App

•Cisco IPMA Service

The Cisco CallManager object contains most of the perfmon counters, and these counters have only one instance. The instance-based counters belonging to the other objects can have zero or more instances. For example, if two phones are registered to Cisco CallManager, two instances of each counter belonging to the Cisco Phones object exist.

The counters within each object contain descriptions. The Microsoft Performance counter descriptions match the Real-Time Monitoring tool counter descriptions. See Chapter 11, "Microsoft Performance" for detailed information about Microsoft performance.

Real-Time Monitoring Tool

The Cisco CallManager Real-Time Monitoring (RTM) tool provides monitoring of Cisco CallManager performance objects and devices. The device information includes device registration status, IP address, description, and model type. RTM provides cluster-wide information stored in six tables. The tables include phone, gateway devices, media, H323 devices, CTI, and voice mail.

RTM also displays perfmon counter information that is kept by each Cisco CallManager node in the cluster. RTM perfmon counters directly monitor the perfmon counters (the same as Microsoft Performance).

The counters within each object contain descriptions. The Microsoft Performance counter descriptions match the RTM counter descriptions.

For more information about Real-Time Monitoring, see Chapter 9, "Real-Time Monitoring."

SNMP MIBs

The Cisco CallManager SNMP extension agent resides in each Cisco CallManager node and exposes the CCM_SNMP_MIB that provides detailed information about devices known to the node. The CCM_SNMP_MIB provides device information such as device registration status, IP address, description, and model type for the node (not the cluster).

The following list identifies the CCM_SNMP_MIB device tables:

•ccmPhoneTable

•ccmPhoneExtensionTable

•ccmPhoneFailedTable

•ccmPhoneStatusUpdateTable

•ccmGatewayTable

•ccmMediaDeviceTable

•ccmCTIDeviceTable

•H323 Device Table

•VoiceMailDeviceTable

CCM_SNMP_MIB supports the following counters:

•ccmRegisteredPhones

•ccmUnregisteredPhones

•ccmRejectedPhones

•ccmRegisteredGateways

•ccmUnregisteredGateways

•ccmRejectedGateways

For more information about SNMP, see Chapter 17, "Simple Network Management Protocol."

Counter Similarities

The perfmon counters for phones and gateways have related or overlapping information that is also used by RTM device monitoring and CCM_SNMP_MIB. See "Cisco CallManager Perfmon Counters, RTMT, and CISCO-CCM-MIB," for related information.
