Mediasessions statistics logs
Since build 5.2.1883a current mediasessions statistics may be collected. The statistics may be logged to save it to a file when mediasession is closed.
The mediasessions statistics is logged to the /usr/local/FlashphonerWebCallServer/logs/stats/media-session-connection-stats.log
file in CSV form

#{mediaSessionId}; {channels_not_writable}; {decodable_drops_old}; {incomplete_drops_old}; {decodable_drops_reset}; {incomplete_drops_reset}; {decodable_drops_pli}; {incomplete_drops_pli}; {data_packets_with_empty_payload}; {missed_h264_units}; {dropped_audio_data_packets} |
Where
- mediaSessionId - mediasession id
- channels_not_writable - TCP channels not writable events count
- decodable_drops_old - H264 decodable frames dropped count
- incomplete_drops_old - H264 incomplete frames dropped count
- decodable_drops_reset - H264 decodable frames dropped before a new decoding point count
- incomplete_drops_reset - H264 incomplete frames dropped before a new decoding point count
- decodable_drops_pli - H264 decodable frames dropped on PLI receiving count
- incomplete_drops_pli - H264 incomplete frames dropped on PLI receiving count
- data_packets_with_empty_payload - data packets with empty payload sent to test a channel quality when TWCC is enabled count
- missed_h264_units - missed H264 units count, per mediasession
- dropped_audio_data_packets - audio packets dropped before passing them to server engine
