Streaming State Statistics Monitoring

The Streaming State Statistics monitor provides statistics about the HTTP streaming videos in your scenario run.

Streaming State Statistics Monitors

Monitor Description

Streaming Time

Monitors the start and buffering times of videos at any given moment in the scenario run.

Streaming Network

Monitors the download speed and video quality of the videos at any given moment in the scenario run.

Streaming Events

Monitors the play, pause, and seek events at any given moment in the scenario run.

Streaming Video

Monitors the number of videos playing or buffering at any given moment in the scenario run.

Streaming State Statistics Measurements

Measurement Description
Time to start(Can play)

The amount of time (in seconds) waited before the video started playing.

When multiple videos are running simultaneously, this value is an average for all the videos.

Buffering pause time

The amount of time (in seconds) waited due to video buffering.

When multiple videos are running simultaneously, this value is an average for all the videos.

Buffering seek time

The amount of time (in seconds) waited due to seeking a part of the video that has not yet been downloaded

When multiple videos are running simultaneously, this value is an average for all the videos.

Buffering rate

Percentage of wait/total time. This is calculated according to:

1 - (playing_time)/(playing_time+open_time+lag_time+seek_time)

When multiple videos are running simultaneously, this value is an average for all the videos.

Video Quality(Bandwidth)

The user/auto selected video quality . This is the bandwidth for the selected quality. If the protocols do not support multi-quality, the quality is 0.

When multiple videos are running simultaneously, this value is an average for all the videos.

Bandwidth

This is the same as the Bandwidth defined in the Speed Simulation runtime settings. Maximum bandwidth is 0.

When multiple videos are running simultaneously, this value is an average for all the videos.

Download speed

Streaming download speed (in Kb/sec).

When multiple videos are running simultaneously, this value is an average for all the videos.

Number of play events Total number of "play" events. This value increments by 1 for each "play" event. e.g. When a video plays, pauses, and then plays again, the value is 2.
Number of seek events Total number of "seek" events. This value increments by 1 for each "seek" event.
Number of pause events Total number of "pause" events. This value increments by 1 for each "pause" event.
Number of download retries Total number of retry events. If downloading of streaming data failed, streaming is not aborted immediately. Streaming is retried according to the number of retries defined in the runtime settings.
Number of buffering video Total number of buffering videos. Increments by 1 when a video is buffering, and decrements by one when the video stops buffering.
Number of lagging video Total number of lagging videos. Increments by 1 when a video is lagging, and decrements by one when the video stops lagging.
Number of playing video Total number of playing videos.
