You can access call logs and metrics for every call to help you better understand your calls and troubleshoot issues as they arise.
Call logs characterize what happens on a call from the point of view of each participant. These logs include information about resource bundle downloads, signaling connections, peer-to-peer & SFU call connections and events, and participants' environments, actions, and error states.
Call metrics help to assess the performance and stability of the connection by providing transport layer, candidate-pair, and track level statistics.
Data starts being collected by the browser client once a second participant joins a call. The first data sample is logged after 15 seconds. Subsequent samples are logged every 15 seconds.
Additionally, we've built a sample app — Daily Call Explorer — as an example of how this information can be used.
