MemoryUsageMetric

@ExperimentalMetricApi
class MemoryUsageMetric : TraceMetric

Metric for tracking the memory usage of the target application.

There are two modes for measurement - Last, which represents the last observed value during an iteration, and Max, which represents the largest sample observed per measurement.

By default, reports:

• memoryRssAnonKb - Anonymous resident/allocated memory owned by the process, not including memory mapped files or shared memory.

• memoryRssAnonFileKb - Memory allocated by the process to map files.

• memoryHeapSizeKb - Heap memory allocations from the Android Runtime, sampled after each GC.

• memoryGpuKb - GPU Memory allocated for the process.

By passing a custom subMetrics list, you can enable other SubMetrics.
