Description: Please cite this dataset as follows:

Yanggratoke, R., Ahmed, and Stadler, R. (2015). Linux kernel statistics from a video-streaming cluster and service metrics from a video client. Distributed by Machine learning data set repository [MLData.org]. http://mldata.org/repository/data/viewslug/realm-cnsm2015-vod-traces

Field descriptions - Field descriptions for X.csv -- [1] "TimeStamp" : Unix epoch time -- [2..*] The fields are in the format {server_index}_{kernel_SAR_stats}, i.e., the fields are prefixed by the server identifier. For example, “X0_all_..usr” refers to average CPU utilisation of all cores from the first server (server 0). For field descriptions, please refer to X_SAR: http://linux.die.net/man/1/sar

  • Field descriptions for Y.csv -- [1] "TimeStamp" : Unix epoch time
    -- [2] "LostFrames" : Lost video frame rate (frames/sec)
    -- [3] “noAudioPlayed" : Audio buffer rate (buffers/sec)
    -- [4] “avgInterAudioPlayedDelay" : Average inter-audio-play delay (seconds) -- [5] NetReadOperations: Network read rate (operations/sec) -- [6] NetReadBytes: Network data read rate (bytes/sec) -- [7] NetReadAvgDelay: Average inter-read delay (seconds) -- [8] "noAudioLost" : Lost audio buffer rate (buffers/sec)
    -- [9] “noAudioLate" : Late audio buffer rate (buffers/sec)
    -- [10] "DispFrames" : Video frame rate (frames/sec) -- [11] "AvgInterDispDelay" : Average video-frame-inter-display delay (seconds)
