Module cdp::heap_profiler

[Experimental]

HeapProfiler

Commands

• HeapProfiler.enable Experimental
• HeapProfiler.disable Experimental
• HeapProfiler.startTrackingHeapObjects Experimental
• HeapProfiler.stopTrackingHeapObjects Experimental
• HeapProfiler.takeHeapSnapshot Experimental
• HeapProfiler.collectGarbage Experimental
• HeapProfiler.getObjectByHeapObjectId Experimental

• HeapProfiler.addInspectedHeapObject Experimental

  Enables console to refer to the node with given id via $x (see Command Line API for more details $x functions).

• HeapProfiler.getHeapObjectId Experimental

• HeapProfiler.startSampling Experimental

• HeapProfiler.stopSampling Experimental

Events

• HeapProfiler.addHeapSnapshotChunk Experimental
• HeapProfiler.resetProfiles Experimental
• HeapProfiler.reportHeapSnapshotProgress Experimental

• HeapProfiler.lastSeenObjectId Experimental

  If heap objects tracking has been started then backend regularly sends a current value for last seen object id and corresponding timestamp. If the were changes in the heap since last event then one or more heapStatsUpdate events will be sent before a new lastSeenObjectId event.

• HeapProfiler.heapStatsUpdate Experimental

  If heap objects tracking has been started then backend may send update for one or more fragments

Types

• HeapSnapshotObjectId Experimental

  Heap snapshot object id.

• SamplingHeapProfileNode Experimental

  Sampling Heap Profile node. Holds callsite information, allocation statistics and child nodes.

• SamplingHeapProfile Experimental

  Profile.
