Voice Faults and Exceptions
A fault is an abnormal condition that occurs when a system or a system component violates a performance threshold or is not functioning properly. An exception is a group of related faults.
VHM groups related faults into a single exception. That is, it generates a single exception of a given type per device, regardless of the number of faults that exist.
The following topics are discussed:

Overview of Faults and Exceptions
By polling SNMP MIBs and subscribing to voice-related events received by DFM, VHM obtains event information to analyze, and generates faults for voice-enabled devices.
Users can review a summary of faults on the Real-Time Dashboard (see the "Using the Real-Time Dashboard" section) and view the generated alarms on the Monitoring Console (see the "Using the Monitoring Console" section).
For additional overview information, see the following topics:
•Device Types that Generate Faults
•Contents of the Fault Tables
Device Types that Generate Faults
VHM generates faults for the voice device groups that comprise the following types of voice-enabled devices:
•Voice Clusters.
•Media Servers.
•ICS 7750.
•Voice Gateways—VHM obtains some of the event information for voice gateways from DFM.
•Inline Power Switches—VHM obtains some of the event information for Inline Power Switches from DFM.
Contents of the Fault Tables
Fault tables include the following types of information:
•Managed entity type where faults can be detected.
•Faults that are detected.
•User-configurable thresholds that are used to define the tolerance limits of each fault condition.
•Exceptions raised by VHM when a fault condition exceeds thresholds.

Operational Exceptions
VHM generates an operational exception for multiple occurrences of the following faults (for a complete list of media server faults, see Table 3-1):

Power Supply Exceptions
VHM generates a power supply exception for multiple occurrences of the following faults (for a complete list of media server faults, see Table 3-1):
•System Battery State is Down/Degraded—Remote Insight Board battery status is not normal. It is either Degrading or Failed.

•Power Supply State Down/Degraded—The power supply is not in a normal state. The possible states are OK, Degraded, and Failed.
Application Exceptions
VHM generates an application exception for multiple occurrences of the following fault (for a complete list of media server faults, see Table 3-1):
•Application Down—Application is not running.
Application Monitor Exceptions
VHM generates an application exception for multiple occurrences of the following fault (for a complete list of media server faults, see Table 3-1):
•Synthetic Phone Registration Failed—Phone registration test failed during a synthetic transaction for a Cisco CallManager (CCM).
•Synthetic Off Hook Transaction Failed—Off-hook test failed during a synthetic transaction for a CCM.
•Synthetic Empty Call Failed—Empty call test failed during a synthetic transaction for a CCM.
•Synthetic End to End Call Failed—End-to-end call test failed during a synthetic transaction for a CCM.
•Synthetic TFTP Download Failed—TFTP download test failed during a synthetic transaction for a CCM.
•Synthetic Phone to Gateway Call Failed—No device picked up a test call to a gateway during a synthetic transaction for a CCM.
•Synthetic Phone to Bridge Call Failed—No device picked up a test call to a conference bridge during a synthetic transaction for a CCM.
•Synthetic Transaction Server Down—The synthetic transaction server is down. Synthetic transaction tests are not being run.
