bytesSent
Total number of RTP packets sent for this SSRC.
Description
Non-negative integer
Total number of RTP packets sent for this SSRC. This includes retransmissions. Calculated as defined in RFC3550 section 6.4.1.
Interpreting Values
- This is a cumulative counter - it only increases over the lifetime of the connection
- The raw value is primarily useful for computing send bitrate. Use bytesSent(bits/s) for real-time analysis
- A flattening of the cumulative curve means sending has stopped or dramatically slowed
Troubleshooting
- Use the calculated bitrate metric for real-time monitoring instead of this raw cumulative value
