CISCO-HEALTH-MONITOR-MIB
AI MIB Summary
The CISCO-HEALTH-MONITOR-MIB aggregates internally generated hardware and software events classified by severity levels (Catastrophic through Low) and correctional states (Positive) to calculate and expose a composite system health metric for Cisco devices. This module enables the tracking of specific detrimental or restorative state changes across the system and its subsystems to quantify operational integrity without relying on individual threshold alerts.
Health Monitor MIB module.
The Health Monitor uses a model based on events of varying severity and frequency, and predefined rules, to generate a metric that represents a system's (and its subsystems') level of health.
The events are typically internally generated notifications in response to detrimental or correctional changes in the state of the hardware or software of the system. Detrimental events are classified under one of the following severity
levels:
Catastrophic - Causes or leads to system failure Critical - Major subsystem or functionality failure High - Potential for major impact to important functions Medium - Potential for minor impact to functionality Low - Negligible impact to functionality
Whilst correctional events fall under the following
classification:
Positive - Not a fault event. May cause or lead to the return of functionality
This MIB module provides information for tracking occurrences of the above events, and presents the associated health metric for the system and its component subsystems.

ciscoHealthMonitorMIBHealth Monitor MIB module.
The Health Monitor uses a model based on events of varying
severity and frequency, and predefined rules, to generate
a metric that represents a system's (and its subsystems')
level of health.
The events are typically internally generated notifications
in response to detrimental or correctional changes in the
state of the hardware or software of the system. Detrimental
events are classified under one of the following severity
levels:
Catastrophic - Causes or leads to system failure
Critical - Major subsystem or functionality failure
High - Potential for major impact to important
functions
Medium - Potential for minor impact to functionality
Low - Negligible impact to functionality
Whilst correctional events fall under the following
classification:
Positive - Not a fault event. May cause or lead to
the return of functionality
This MIB module provides information for tracking occurrences
of the above events, and presents the associated health
metric for the system and its component subsystems. MODULE-IDENTITY .1.3.6.1.4.1.9.9.243 |

ciscoHealthMonitorHealthLevelA ciscoHealthMonitorHealthLevel notification is sent when
the health of a subsystem reaches either the
ciscoHealthMonitorHealthNotifyLowThreshold or
ciscoHealthMonitorHealthNotifyHighThreshold threshold
as described above. NOTIFICATION-TYPE .1.3.6.1.4.1.9.9.243.0.1 |

ciscoHealthMonitorTableThis table contains Health Monitor statistics for physical
entities and their constituent hardware and/or software
subsystems.
The Health Monitor statistics present in each row provide
information such as the computed health of the indicated
subsystem and the number of faults it has experienced. SEQUENCE OF CiscoHealthMonitorEntry .1.3.6.1.4.1.9.9.243.1.1 |
ciscoHealthMonitorEntryA Health Monitor statistics entry.
The entPhysicalIndex identifies the physical entity (chassis
or container), while the ciscoHealthMonitorSubsysName
identifies by name the appropriate subsystem for which these
statistics apply.
If there are other entities such as peer routers or line
cards then, in the context of this MIB, these are also
defined to be in the same system. If these entities also
run an instance of the Health Monitor then the summary
information from the distributed Health Monitors is
obtained here. CiscoHealthMonitorEntry .1.3.6.1.4.1.9.9.243.1.1.1 |
ciscoHealthMonitorSubsysNameA textual string containing the name of the hardware or
software subsystem. A management station wishing to obtain
summary statistics for a physical entity should use a value
of 'system' for this object. SnmpAdminString .1.3.6.1.4.1.9.9.243.1.1.1.1 |
ciscoHealthMonitorHealthThe computed current health of this subsystem on the
specified entity.
This health metric is based on predefined rules that
specify how the health should be adjusted in response to
certain events of varying severity and frequency. As these
events are encountered by each subsystem or physical entity,
the appropriate rules are applied and the health is modified
accordingly.ro HealthLevel UNITS "0.01 percent" .1.3.6.1.4.1.9.9.243.1.1.1.2 |
ciscoHealthMonitorHealthNotifyEnableEnables or disables health level notifications. When set
to true(1), the ciscoHealthMonitorHealthLevel notification
is enabled. When set to false(0), the
ciscoHealthMonitorHealthLevel notification is disabled.
If such a notification is desired, it is the responsibility of
the management entity to ensure that the SNMP administrative
model is configured in such a way as to allow the notification
to be delivered.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.243.1.1.1.3 |
ciscoHealthMonitorHealthNotifyHighThresholdSpecifies the health level at which a
ciscoHealthMonitorHealthLevel notification will be
generated for the specified subsystem and entity.
A notification will only be generated if the health
level had previously reached the low threshold level
prior to reaching this high threshold level.
Health levels oscillating within the high and the low
threshold levels do not generate notifications.
A health level going from low threshold (or below)
to high threshold (or above) represents a return
to normal health for the specified subsystem.
Set your optimal health level to this threshold.rw HealthLevel UNITS "0.01 percent" .1.3.6.1.4.1.9.9.243.1.1.1.4 |
ciscoHealthMonitorHealthNotifyLowThresholdSpecifies the health level at which a
ciscoHealthMonitorHealthLevel notification will be
generated for the specified subsystem and entity.
A notification will only be generated if the health
level had previously reached the high threshold level
prior to reaching this low threshold level.
Health levels oscillating within the high and the low
threshold levels do not generate notifications.
A health level going from high threshold (or above)
to low threshold (or below) represents a deterioration
of the health for the specified subsystem.
Set your unacceptable health level to this threshold.rw HealthLevel UNITS "0.01 percent" .1.3.6.1.4.1.9.9.243.1.1.1.5 |

this subsystem on the specified entity since the system
