Threshold monitoring

Threshold monitoring enables the NQA client to take a predefined action when the NQA operation performance metrics violate the specified thresholds.

Table 1 describes the relationships between performance metrics and NQA operation types.

Table 1: Performance metrics and NQA operation types

Performance metric

NQA operation types that can gather the metric

Probe duration

All NQA operation types except UDP jitter, UDP tracert, path jitter, and voice

Number of probe failures

All NQA operation types except UDP jitter, UDP tracert, path jitter, and voice

Round-trip time

ICMP jitter, UDP jitter, and voice

Number of discarded packets

ICMP jitter, UDP jitter, and voice

One-way jitter (source-to-destination or destination-to-source)

ICMP jitter, UDP jitter, and voice

One-way delay (source-to-destination or destination-to-source)

ICMP jitter, UDP jitter, and voice

Calculated Planning Impairment Factor (ICPIF) (see "Configuring the voice operation")

Voice

Mean Opinion Scores (MOS) (see "Configuring the voice operation")
