Usage Guidelines

Usage Scenario

Proactive measurement works continuously to collect statistics. To implement performance measurement continuously, run the test start-continual command to enable proactive measurement.

Prerequisites

A session has been created on the Control-Client.

Precautions

After a test session is deleted, the proactive measurement configuration for the test session will be deleted.
After a Session-Sender is deleted, all proactive measurement configurations will be deleted.
When on-demand measurement is running, if proactive measurement is started, on-demand measurement is immediately stopped, and proactive measurement starts to work.
On-demand measurement may fail when board resources are insufficient. If the display twamp-light test-session command output shows inactive in the State option, on-demand measurement fails.
