consecutive—If the number of consecutive times that the monitored performance metric is out of the

specified value range reaches or exceeds the specified threshold, a threshold violation occurs.

Threshold violations for the average or accumulate threshold type are determined on a per NQA

operation basis, and threshold violations for the consecutive type are determined from the time the NQA

operation starts.

Triggered actions

The following actions might be triggered:

none—NQA displays results only on the terminal screen. It does not send traps to the NMS.

trap-only—NQA displays results on the terminal screen, and meanwhile it sends traps to the NMS.

trigger-only—NQA displays results on the terminal screen, and meanwhile triggers other modules
for collaboration.

The DNS operation does not support the action of sending trap messages.

Reaction entry

In a reaction entry, a monitored element, a threshold type, and an action to be triggered are configured

to implement threshold monitoring.
The state of a reaction entry can be invalid, over-threshold, or below-threshold.

Before an NQA operation starts, the reaction entry is in invalid state.

If the threshold is violated, the state of the entry is set to over-threshold. Otherwise, the state of the

entry is set to below-threshold.

If the action to be triggered is configured as trap-only for a reaction entry, when the state of the entry

changes, a trap message is generated and sent to the NMS.

Configuration procedure

Before you configure threshold monitoring, configure the destination address of the trap messages by

using the snmp-agent target-host command. For more information about the command, see Network
Management and Monitoring Command Reference
.
To configure threshold monitoring:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Create an NQA
operation and

enter NQA

operation view.

nqa entry admin-name operation-tag

By default, no NQA operation
is created.

3.

Enter NQA
operation view.

type { dhcp | dlsw | dns | ftp | http | icmp-echo
| snmp | tcp | udp-echo | udp-jitter | voice }

Path jitter does not support the
threshold monitoring function.

4.

Enable sending
traps to the NMS

when specific

conditions are met.

reaction trap { probe-failure
consecutive-probe-failures | test-complete |

test-failure cumulate-probe-failures }

By default, no traps are sent to
the NMS.
The UDP jitter and voice
operations only support the

test-complete keyword.
