Supported Threshold Configuration Metrics

You can configure threshold on the following metrics based on the selected service type:

Polling for two way packet loss metric is supported for all the probe types. However, threshold configuration for two way packet loss metric is supported only for ICMP Jitter and UDP probe types.

For ICMP Jitter and UDP probe types (Juniper devices), the following metrics are collected only if one way hardware time stamp is enabled for a probe:

  • Positive Jitter SD
  • Positive Jitter DS
  • Negative Jitter SD
  • Negative Jitter DS

If one way hardware time stamp is changed for a probe between two discovery cycles, the metrics collected also changes accordingly. However, the change in the metrics collected takes effect only from the next discovery cycle. For example, a probe with one way hardware time stamp disabled does not collect the metrics listed above. However, if one way hardware time stamp is enabled later, the probe will collect all the metrics listed above, but this change takes effect only after the next discovery cycle.
