Key events

For each user whose View metrics switch is turned on, this section shows their events during the selected time range in two views: Timeline and list.

Timeline

The circles on the timeline represent events. A larger circle means more events occurred at that time. If a noteworthy event occurred, the circle is marked red.

In the timeline view, you can do the following:

• Hover your mouse over a circle to view event logs.
• Click the zoom-in or zoom-out icon in the upper right corner to adjust the time scale.

List

The list view has three columns: Time, event type, and event. The list is displayed side by side with the corresponding user's audio and video quality metrics.

• Select one or more event types using the drop-down menu in the upper right corner, including login and logout, network transmission, video sending, video receiving, audio sending, and audio receiving.

Audio and video quality metrics

With the core audio and video metrics displayed in the sender's and receiver's view, this section shows the quality of experience within the selected time range for each user whose View metrics switch is turned on (referred to as "selected users").

The metrics are defined in User-specific metrics.
