Question: How to get peer connection metrics (RTCStatsReport)?

[yulian948]

In https://github.com/aws/amazon-chime-sdk-js there is a ClientMetricReport class, which contains RTCStatsReport. Is there anything similar in the Chime iOS SDK? Currently, I only see the MetricsObserver::metricsDidReceive method, which returns a dictionary of metrics but is limited to the metrics defined in ObservableMetric enum.

Hello,

Currently we only have the metrics defined in ObservableMetric. I'll mark this as a feature request for additional metrics similar to RTCStatsReport in amazon-chime-sdk-js. Is there a particular metric that you were looking for?

Thanks for your answer @alnlau! It would be awesome to have access to RTCStatsReport. No particular metric, I just want to have more of them available, the same as I have when using WebRTC.

In the meantime, while looking through the code, I found ClientMetricsCollector protocol which is implemented by DefaultClientMetricsCollector class. There is a comment in that protocol:

... takes the raw metrics from the native client ...

Does it mean that I can implement that protocol in my app and receive more metrics than currently available through ObservableMetric enum?

Answering my previous question: It is not possible to implement ClientMetricsCollector protocol and use own implementation instead of DefaultClientMetricsCollector, because it is not possible to replace it in DefaultMeetingSession.swift.

Bump this as we need something similar to audioDownstreamJitterMs , audioUpstreamJitterMs and audioUpstreamRoundTripTimeMs which are all implemented in the js sdk
