Monitor an active stream


The Wowza Streaming Cloud™ service monitors resources continually. When a live stream or transcoder is running, you can get a quick view of statistics about how it's connecting and transcoding.

  1. Do one of the following:
  • On the Live Streams page, click any started stream.
  • On the Transcoders page, click any started transcoder.
  1. Look at the Statistics panels on the Overview tab of the stream or transcoder detail page to see connection, transcoding, and delivery metrics.

  • Inbound: Connected – Yes indicates that the video source or encoder is connected to Wowza Streaming Cloud.
  • Inbound Bitrate: Actual – The rate of the stream traveling from the encoder to Wowza Streaming Cloud, in kilobits per second (Kbps).
  • Outbound Bitrate: Actual – The total actual bitrate of all outbound video renditions, in kilobits per second (Kbps).
  • Outbound Bitrate: Configured – The total configured bitrate of all outbound video streams, in kilobits per second (Kbps). Not shown for passthrough transcoders.
  • CPU Usage – The percentage of available CPU power on the virtual host being used by the transcoder.
  • GPU Encoder Usage – The percentage of available GPU encoding power on the virtual host being used by the transcoder. Appears only for active 4K streams.
  • GPU Decoder Usage – The percentage of available GPU decoding power on the virtual host being used by the transcoder. Appears only for active 4K streams.
  • Frame Size – The configured frame size of the source video, in pixels. A warning appears if the configured frame size differs from the actual frame size being received from the source by Wowza Streaming Cloud.
  • Frame Rate – The frame rate of the video, in frames per second, at the transcoder. A warning appears if the frame rate is too low, which might indicate a problem at the stream source, or if it's too high, which might overload the transcoder's CPU.
  • Keyframe Interval – The number of video frames compressed in a group of pictures (GOP) between keyframes at the transcoder. A warning appears if the keyframe interval varies from the recommended rate of being equal to or twice the frame rate.
  • Total Unique Viewers – The total number of times the live stream or transcoder has been viewed. A single unique view is one IP address receiving at least one chunk of the stream on any player or device in a 24-hour period. A chunk is a segment of video that's 10 seconds or shorter.
Notes:
  • All times appear in the user's local time.
  • The Video Thumbnail updates every 5 seconds.
  • All statistics refresh every 10 seconds, except Total Unique Viewers, which begins to update approximately 2 hours after the stream starts and then updates approximately hourly.
  • Total Unique Viewers may take up to 48 hours to finalize after the stream ends.

  • Click Monitor on the menu bar to view a reversible tile for each started stream.
  • Click Statistics in the lower-right corner of a tile to view connection, transcoding, and delivery details for the stream.

  • Click Thumbnail in the lower-right corner of a tile to see a frame thumbnail for the stream.

  • Click the go-to icon in the upper-right corner of a tile to go to the hosted page for the stream, if there is one.
  • Click the live stream name in the upper-left of a tile to go to the stream's detail page.
