Parameters

categories (Optional)

Type: System.String
Category/tag filter

options (Optional)

Type: System.String
Tracing options

bufferUsageReportingInterval (Optional)

Type: System.Nullable<Double>
If set, the agent will issue bufferUsage events at this interval, specified in milliseconds

transferMode (Optional)

Type: System.Nullable<StartTransferMode>
Whether to report trace events as series of dataCollected events or to save trace to astream (defaults to `ReportEvents`).

streamFormat (Optional)

Type: System.Nullable<StreamFormat>
Trace data format to use. This only applies when using `ReturnAsStream`transfer mode (defaults to `json`).

streamCompression (Optional)

Type: System.Nullable<StreamCompression>
Compression format to use. This only applies when using `ReturnAsStream`transfer mode (defaults to `none`)

traceConfig (Optional)

Type: CefSharp.DevTools.Tracing.TraceConfig
traceConfig

perfettoConfig (Optional)

Type:System.Byte[]
Base64-encoded serialized perfetto.protos.TraceConfig protobuf messageWhen specified, the parameters `categories`, `options`, `traceConfig`are ignored.

tracingBackend (Optional)

Type: System.Nullable<TracingBackend>
Backend type (defaults to `auto`)

Return Value
