The stream health monitor in the Wowza Video™ service graphs metrics about source connections and transcoding processes for any live stream or transcoder. Viewing the stream health monitor can help you to understand how efficiently and successfully a stream is received and processed by Wowza Video.
- Historic metrics refresh every 20 seconds. If the source encoder disconnects from Wowza Video between refreshes, the graph shows the disconnection as a zero value. Brief irregularities might not register or be tracked and visualized.
- Metrics for streams that started before June 6, 2017, may be incomplete or missing.

Live Stream
View current health metrics for an active live stream
- Click Live Streams on the menu bar, and select a running (started) live stream.
- Click the Health tab.
The Stream Health Monitor displays:
- Inbound Bitrate – The actual rate of the stream traveling from the source encoder to Wowza Video, in kilobits per second (Kbps). This may differ from the configured inbound bitrate.
- Outbound Bitrate – The actual bitrate of all outbound video renditions, in kilobits per second (Kbps). This may differ from the configured outbound bitrate.
- Frame Rate – The rate of the video, in frames per second, at the transcoder.
- Keyframe Interval – The number of video frames compressed in a group of pictures (GOP) between keyframes at the transcoder.
View historic health metrics for a live stream
- Click Live Streams on the menu bar, and select a live stream that has run at least once.
- Click the Health tab.
- Choose a stream session from the Select a streaming session menu.
Sessions are listed by their start date and time and show how long the stream ran.
- (Optional) Narrow the date/time range by using the From and To fields.
- Click Show.
The Stream Health Monitor displays the Inbound Bitrate, Outbound Bitrate, Frame Rate, and Keyframe Interval.
- (Optional) Move the cursor over any point on the graph to view a metric's value at a specific point in time.
Transcoder
View current health metrics for an active transcoder
- Click Advanced on the menu bar, click Transcoders, and then select a running (started) transcoder.
- Click the Health tab.
The Stream Health Monitor displays the following metrics:
- Inbound Bitrate – The actual rate of the stream traveling from the source encoder to Wowza Video, in kilobits per second (Kbps). This may differ from the configured inbound bitrate.
- Outbound Bitrate – The actual bitrate of all outbound video renditions, in kilobits per second (Kbps). This may differ from the configured outbound bitrate.
- Frame Rate – The rate of the video, in frames per second, at the transcoder.
- Keyframe Interval – The number of video frames compressed in a group of pictures (GOP) between keyframes at the transcoder.
