· When you specify the set action, the system automatically creates a set entry and enters action-set view. You can configure the set action in this view. For more information, see the configuration in action-set view.

· When you specify the notification action, the system automatically creates a notification entry and enters action-notification view. You can configure the notification action in this view. For more information, see the configuration in action-notification view.

comparison

Use comparison to specify a Boolean comparison type for the sampled value and the reference value.

Use undo comparison to restore the default.

Syntax

comparison { equal | greater | greaterorequal | less | lessorequal | unequal }

undo comparison

Default

The Boolean comparison type is unequal.

Views

Trigger-Boolean view

Predefined user roles

network-admin

Parameters

equal: Specifies the Boolean comparison type as equal. When the sampled value equals the reference value, the trigger condition is met.

greater: Specifies the Boolean comparison type as greater than. When the sampled value is greater than the reference value, the trigger condition is met.

greaterorequal: Specifies the Boolean comparison type as greater than or equal to. When the sampled value is greater than or equal to the reference value, the trigger condition is met.

less: Specifies the Boolean comparison type as smaller than. When the sampled value is smaller than the reference value, the trigger condition is met.

lessorequal: Specifies the Boolean comparison type as smaller than or equal to. When the sampled value is smaller than or equal to the reference value, the trigger condition is met.

unequal: Specifies the Boolean comparison type as unequal. When the sampled value is unequal to the reference value, the trigger condition is met.

Usage guidelines

If the sampled value meets the trigger condition at two or more samplings in succession, an event is triggered only at the first sampling.

For an event to be triggered at the first sampling, execute the startup enable command.

Examples

# Specify the Boolean comparison type as unequal.

Parameters

event owner event-owner name event-name: Specifies an event by its owner and its name. Use the trigger owner as the event owner. The event-name argument is a case-sensitive string of 1 to 32 characters.

Usage guidelines

An object list is identified by its owner, name, and index. The specified objects in the object list will be carried in the triggered notification to the NMS.

Examples

# Configure an object list identified by owner owner1, name objectA, and index 10. Specify the object identified by OID 1.3.6.1.2.1.2.2.1.1.3 to be carried in the triggered notification.

Use undo snmp mib event sample instance maximum to restore the default.

Syntax

undo snmp mib event sample instance maximum

Default

The maximum number of object instances that can be concurrently sampled is limited by the available resources. The value is 0.

Views

System view

Predefined user roles

network-admin

Parameters

max-number: Specifies the maximum number of object instances that can be concurrently sampled. The value is in the range of 0 to 4294967295.

Usage guidelines

If you use the wildcard option for an object, Event MIB also samples the wildcarded object instances. Include the wildcarded object instances when you calculate the number of the concurrently sampled instances.

Changing the maximum number of object instances that can be concurrently sampled does not affect the existing instances. If the maximum number of object instances that can be concurrently sampled is changed to a value smaller than the number of existing instances, the existing instances will continue to be sampled.

Examples

# Set the maximum number to 10 for the object instances that can be concurrently sampled.

<Sysname> system-view

[Sysname] snmp mib event sample instance maximum 10

snmp mib event sample minimum

Use snmp mib event sample minimum to specify the minimum sampling interval.

Views

System view

Predefined user roles

Parameters

min-number: Specifies the minimum sampling interval in the range of 1 to 2147483647, in seconds.

Usage guidelines

After you configure the minimum sampling interval, make sure the trigger sampling interval is greater than or equal to the minimum sampling interval.

Changing the minimum sampling interval does not affect the existing instances. If the minimum sampling interval is changed to a value smaller than the sampling interval of a trigger, the existing instances of the trigger will continue to be sampled at its interval.

Examples

# Set the minimum sampling interval to 50 seconds.

network-admin

Parameters

trigger-owner: Specifies a trigger owner, which must be an existing SNMPv3 user.

trigger-name: Specifies a trigger name, a case-sensitive string of 1 to 32 characters.

Usage guidelines

A trigger is identified by its owner and name. In trigger view, you can specify a monitored object and set an interval for sampling the object. An event is triggered when the sampled object meets the trigger condition.

If the trigger owner has no read access to the monitored object configured in trigger view, sampling on the object cannot be performed. For more information about SNMPv3 user access rights, see Network Management and Monitoring Configuration Guide.

Examples

# Create a trigger identified by owner owner1 and name triggerA.

<Sysname> system-view

[Sysname] snmp mib event trigger owner owner1 name triggerA

snmp-agent trap enable event-mib

Use snmp-agent trap enable event-mib to enable the Event MIB trap feature.

Use undo snmp-agent trap enable event-mib to disable the Event MIB trap feature.

Syntax

undo snmp-agent trap enable event-mib

Default

The Event MIB trap feature is enabled.

Views

System view

Predefined user roles

network-admin

Usage guidelines

After you enable the Event MIB trap feature, traps are generated when object sampling fails or a trigger condition is met and sent to the SNMP module. Traps include trigger trap, rising threshold break trap, falling threshold break trap, trigger-condition detection failure trap, and set-action trigger failure trap.

For the traps to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see Network Management and Monitoring Configuration Guide.

Examples

# Enable the event MIB trap feature.

<Sysname> system-view

[Sysname] snmp-agent trap enable event-mib

startup (trigger-existence view)

Use startup to specify existence trigger test types for the first sampling.

Use undo startup to remove the existence trigger test types for the first sampling.

Syntax

Default

The existence trigger test types for the first sampling are present and absent.

Views

Trigger-existence view

Predefined user roles

network-admin

Parameters

absent: Monitors the absence of a MIB object.

present: Monitors the presence of a MIB object.

Usage guidelines

For the first sampling, an event is triggered when the following conditions are met:

· Both the startup and type commands specify the existence test type as present and the state of the monitored object changes to present at the first sampling. If the monitored objects are wildcarded, the event is triggered independently for each wildcarded object.

· Both the startup command and type commands specify the existence trigger test type as absent and the state of the monitored object changes to absent at the first sampling. If the monitored objects are wildcarded, no event is triggered.

Examples

# Remove the present test configuration for the first sampling.

Parameters

falling: Specifies the falling trap.

rising: Specifies the rising trap.

rising-or-falling: Specifies the rising or falling trap.

Usage guidelines

If the trap type for the first sampling is rising or rising-or-falling, a rising trap is triggered when the first sample value is greater than or equal to the rising threshold.

If the trap type for the first sampling is rising or rising-or-falling, a falling trap is triggered when the first sample value is smaller than or equal to the rising threshold.

If the first sampling fails or the monitored object does not exist at the first sampling, the second sampling is considered the first sampling.

Examples

# Specify the rising trap for the first sampling.
