Configuring threshold monitoring

This feature allows you to monitor the NQA operation running status.

Threshold types

An NQA operation supports the following threshold types:

Threshold violations for the average or accumulate threshold type are determined on a per NQA operation basis. The threshold violations for the consecutive type are determined from the time the NQA operation starts.

Triggered actions

The following actions might be triggered:

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

Reaction entry

In a reaction entry, configure a monitored element, a threshold type, and an action to be triggered to implement threshold monitoring.

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

If the action is trap-only for a reaction entry, a trap message is sent to the NMS when the state of the entry changes.

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 operations exist.

3. Enter NQA operation view.

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

The threshold monitoring feature is not available for the path jitter operation.

4. Enable sending traps to the NMS when specific conditions are met.

reaction trap { path-change | probe-failure consecutive-probe-failures | test-complete | test-failure [ accumulate-probe-failures ] }

By default, no traps are sent to the NMS.

The ICMP jitter, UDP jitter, and voice operations support only the test-complete keyword.

The following parameters are not available for the UDP tracert operation:

  • The probe-failure consecutive-probe-failures option.

  • The accumulate-probe-failures argument.

5. Configure threshold monitoring.

  • Monitor the operation duration (not supported in the ICMP jitter, UDP jitter, UDP tracert, or voice operations):reaction item-number checked-element probe-duration threshold-type { accumulate accumulate-occurrences | average | consecutive consecutive-occurrences } threshold-value upper-threshold lower-threshold [ action-type { none | trap-only } ]

  • Monitor failure times (not supported in the ICMP jitter, UDP jitter, UDP tracert, or voice operations):reaction item-number checked-element probe-fail threshold-type { accumulate accumulate-occurrences | consecutive consecutive-occurrences } [ action-type { none | trap-only } ]

  • Monitor the round-trip time (only for the ICMP jitter, UDP jitter, and voice operations):reaction item-number checked-element rtt threshold-type { accumulate accumulate-occurrences | average } threshold-value upper-threshold lower-threshold [ action-type { none | trap-only } ]

  • Monitor packet loss (only for the ICMP jitter, UDP jitter, and voice operations):reaction item-number checked-element packet-loss threshold-type accumulate accumulate-occurrences [ action-type { none | trap-only } ]

  • Monitor the one-way jitter (only for the ICMP jitter, UDP jitter, and voice operations):reaction item-number checked-element { jitter-ds | jitter-sd } threshold-type { accumulate accumulate-occurrences | average } threshold-value upper-threshold lower-threshold [ action-type { none | trap-only } ]

  • Monitor the one-way delay (only for the ICMP jitter, UDP jitter, and voice operations):reaction item-number checked-element { owd-ds | owd-sd } threshold-value upper-threshold lower-threshold

  • Monitor the ICPIF value (only for the voice operation):reaction item-number checked-element icpif threshold-value upper-threshold lower-threshold [ action-type { none | trap-only } ]

  • Monitor the MOS value (only for the voice operation):reaction item-number checked-element mos threshold-value upper-threshold lower-threshold [ action-type { none | trap-only } ]
