TraceCategoriesAndOptions Object 
- categoryFilterstring - A filter to control what category groups should be traced. A filter can have an optional '-' prefix to exclude category groups that contain a matching category. Having both included and excluded category patterns in the same list is not supported. Examples:- test_MyTest*,- test_MyTest*,test_OtherStuff,- -excluded_category1,-excluded_category2.
- traceOptionsstring - Controls what kind of tracing is enabled, it is a comma-delimited sequence of the following strings:- record-until-full,- record-continuously,- trace-to-console,- enable-sampling,- enable-systrace, e.g.- 'record-until-full,enable-sampling'. The first 3 options are trace recording modes and hence mutually exclusive. If more than one trace recording modes appear in the- traceOptionsstring, the last one takes precedence. If none of the trace recording modes are specified, recording mode is- record-until-full. The trace option will first be reset to the default option (- record_modeset to- record-until-full,- enable_samplingand- enable_systraceset to- false) before options parsed from- traceOptionsare applied on it.
