Streams impacted by in focus

This page covers the Streams impacted by in focus reporting metric. See In focus for how to collect this variable.

The Streams impacted by in focus metric counts sessions in which the player was in focus at least once. The metric is a session-level boolean — multiple focus events within the same session count as one impacted stream. For total focus event volume, use In focus counts.

How this metric is calculated

The media backend sets this flag the first time a focus state-start event is received during the session. The metric is reported on the close call.
