## Enumerations

|  Enumeration | Description |

## Interfaces

|  Interface | Description |
|  --- | --- |
|  [BufferUsageEvent](./puppeteer.protocol.tracing.bufferusageevent.md) |  |
|  [DataCollectedEvent](./puppeteer.protocol.tracing.datacollectedevent.md) | Contains an bucket of collected trace events. When tracing is stopped collected events will be send as a sequence of dataCollected events followed by tracingComplete event. |
|  [GetCategoriesResponse](./puppeteer.protocol.tracing.getcategoriesresponse.md) |  |
|  [MemoryDumpConfig](./puppeteer.protocol.tracing.memorydumpconfig.md) | Configuration for memory dump. Used only when "memory-infra" category is enabled. |

|  [RequestMemoryDumpResponse](./puppeteer.protocol.tracing.requestmemorydumpresponse.md) |  |
|  [StartRequest](./puppeteer.protocol.tracing.startrequest.md) |  |
|  [TraceConfig](./puppeteer.protocol.tracing.traceconfig.md) |  |
|  [TracingCompleteEvent](./puppeteer.protocol.tracing.tracingcompleteevent.md) | Signals that tracing is stopped and there is no trace buffers pending flush, all data were delivered via dataCollected events. |

## Type Aliases

|  Type Alias | Description |
|  --- | --- |
|  [StreamCompression](./puppeteer.protocol.tracing.streamcompression.md) | Compression type to use for traces returned via streams. |
