#sampling-heap-profiler

Out of process heap profiling start mode.
Creates a profiling service that records stacktraces for all live, malloced objects. Heap dumps can be obtained at chrome://tracing [category:memory-infra] and chrome://memory-internals. This setting controls which processes are profiled. As long as this setting is not disabled, users can start profiling any given process in chrome://memory-internals. – Mac, Windows, Linux, Chrome OS, Android

#memlog

Emit small allocations in memlog heap dumps.
By default, small allocations are pruned from the heap dump. This reduces the size of the compressed trace by 100x. If pruning is disabled, the chrome://tracing UI may be unable to take or load the trace. Save the trace directly using chrome://memory-internals, and use other mechanisms [e.g. diff_heap_profiler.py] to examine the trace. Note that automatically uploaded traces will always be pruned. This only affects manually taken memory-infra traces. – Mac, Windows, Linux, Chrome OS, Android

#memlog-keep-small-allocations

Sample memlog allocations
Use a poisson process to sample allocations. Defaults to a sample rate of 10000. This results in low noise for large and/or frequent allocations [[size * frequency >> 10000]. This means that aggregate numbers [e.g. total size of malloc-ed objects] and large and/or frequent allocations can be trusted with high fidelity. – Mac, Windows, Linux, Chrome OS, Android

#memlog-sampling

The type of stack to record for memlog heap dumps
By default, memlog heap dumps record native stacks, which requires a post-processing step to symbolize. Requires a custom build with frame pointers to work on Android. Native with thread names will add the thread name as the first frame of each native stack. It's also possible to record a pseudo stack using trace events as identifiers. It's also possible to do a mix of both. – Mac, Windows, Linux, Chrome OS, Android
