The following updates were pushed to ZEN Master on April 1, 2019.


STREAM VISUALIZATION



Stream visualizations graphically display the components that make up a ZEN Master Channel -
Source(s), Target(s), Feeder(s), Broadcaster(s), Receivers(s), and Cluster(s) – as well as the
connections between these components. For each of these components, their current state is shown
as well as additional details. A link to navigate directly to each component’s page is also shown.
Currently, Chrome and Firefox are supported for stream visualization whereas Internet Explorer and
Edge are not.

To visualize a channel, select the Diagram tab when viewing the channel.

The diagram can be zoomed out to fit the width of the current window by clicking the zoom button.

For narrow screens the diagram will be oriented in a vertical direction. The zoom button has no
effect in this orientation.

SETTING BROADCASTER CLUSTER ALERT THRESHOLDS



When adding or editing a Broadcaster Cluster, the user now can modify the error alert threshold
values for Broadcaster CPU usage, Memory usage, Hard Drive usage, GPU usage, GPU Memory usage
as well as the warning alerts threshold values for GPU Decoder usage and GPU Encoder usage. The
GPU thresholds are only relevant for transcoding workflows using Intel Quick Sync and NVIDIA GPUs.
To set the thresholds, click on SHOW ADVANCED when adding or editing a Broadcaster cluster.
