TracingBackend Enumeration

Backend type to use for tracing. `chrome` uses the Chrome-integrated tracing service and is supported on all platforms. `system` is only supported on Chrome OS and uses the Perfetto system tracing service. `auto` chooses `system` when the perfettoConfig provided to Tracing.start specifies at least one non-Chrome data source; otherwise uses `chrome`.
