 Once enabled, various "breadcrumb" events (such as application going to background, logging message, network connectivity lost and many more) will be submitted with all types of Backtrace reports and viewable in the web console. It is possible to configure client-side which events to include and from which log level severity. By default the breadcrumbs are limited to 64kB and older events will automatically be cleaned up.
