Removed on 2014-03-13. This switch was listed in cc/base/switches.cc.
--trace-shutdown Causes TRACE_EVENT flags to be recorded beginning with shutdown. Optionally, can specify the specific trace categories to include (e.g. --trace-shutdown=base,net) otherwise, all events are recorded. --trace-shutdown-file can be used to control where the trace log gets stored to since there is otherwise no way to access the result.
Removed on 2014-11-14. This switch was listed in content/public/common/content_switches.cc.
--trace-shutdown-file If supplied, sets the file which shutdown tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-shutdown is also supplied. Example: --trace-shutdown --trace-shutdown-file=/tmp/trace_event.log
Removed on 2014-11-14. This switch was listed in content/public/common/content_switches.cc.
--trace-startup Causes TRACE_EVENT flags to be recorded from startup. Optionally, can specify the specific trace categories to include (e.g. --trace-startup=base,net) otherwise, all events are recorded. Setting this flag results in the first call to BeginTracing() to receive all trace events since startup. In Chrome, you may find --trace-startup-file and --trace-startup-duration to control the auto-saving of the trace (not supported in the base-only TraceLog component).
Removed on 2014-11-14. This switch was listed in content/public/common/content_switches.cc.

Removed on 2014-11-14. This switch was listed in content/public/common/content_switches.cc.
--trace-startup-file If supplied, sets the file which startup tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-startup is also supplied. Example: --trace-startup --trace-startup-file=/tmp/trace_event.log As a special case, can be set to 'none' - this disables automatically saving the result to a file and the first manually recorded trace will then receive all events since startup.
Removed on 2014-11-14. This switch was listed in content/public/common/content_switches.cc.
