Add net log events more frequently on network quality changes |
||
Issue descriptionCurrently, NQE adds network quality change events to net log if the effective connection type changes or if RTT estimate is available, and it was not available before. NQE should add net log events more frequently. For example, if the RTT estimate changes more than X msec, then add a net log event. This would be useful for debugging and providing increased visibility as NQE starts exposing more precise estimates of RTT and throughput to outside consumers.
