Chapter 5 Cisco Unified Real-Time Monitoring Tool Tracing, PerfMon Counters, and Alerts
Performance Monitoring in RTMT
MTPResourceAvailable This counter represents the total number of MTP resources that are not in use and
are available to be allocated on all MTP devices that are registered with Cisco
Unified Communications Manager. Each MTP resource uses two streams. An
MTP in use represents one MTP resource that has been allocated for use in a call.
MTPResourceTotal This counter represents the total number of media termination point (MTP)
resources that are provided by all MTP devices that are currently registered with
Cisco Unified Communications Manager.
MTP_RequestsThrottled This counter represents the total number of media termination point (MTP)
resource requests that have been denied due to throttling (a resource from this
MTP was not allocated because, as specified by the Cisco CallManager service
parameter MTP and Transcoder Resource Throttling Percentage, the MTP was
being utilized beyond the configured throttle percentage). This counter
increments each time a resource is requested from this MTP and is denied due to
throttling. This counter reflects a running total since the MTP device registered
with the Cisco CallManager service.
PartiallyRegisteredPhone This counter represents the number of partially registered phones that are running
SIP.
PRIChannelsActive This counter represents the number of PRI voice channels that are in an active call
on a Cisco Unified Communications Manager.
PRISpansInService This counter represents the number of PRI spans that are currently available for
use.
RegisteredAnalogAccess This counter represents the number of registered Cisco analog access gateways
that are registered with system. The count does not include the number of Cisco
analog access ports.
RegisteredHardwarePhones This counter represents the number of Cisco hardware IP phones (for example,
Cisco Unified IP Phones 7960, 7940, 7910, and so on.) that are currently
registered in the system.
RegisteredMGCPGateway This counter represents the number of MGCP gateways that are currently
registered in the system.
RegisteredOtherStationDevices This counter represents the number of station devices other than Cisco hardware
IP phones that are currently registered in the system (for example,
Cisco IP SoftPhone, CTI port, CTI route point, Cisco voice-mail port).
SIPLineServerAuthorizationChallenges This counter represents the number of authentication challenges for incoming SIP
requests that the Cisco Unified Communications Manager server issued to phones
that are running SIP. An authentication challenge occurs when a phone that is
running SIP with Digest Authentication enabled sends a SIP line request to Cisco
Unified Communications Manager.
SIPLineServerAuthorizationFailures This counter represents the number of authentication challenge failures for
incoming SIP requests from SIP phones to the Cisco Unified Communications
Manager server. An authentication failure occurs when a SIP phone with Digest
Authentication enabled sends a SIP line request with bad credentials to Cisco
Unified Communications Manager.
