Struct HeapProfiler

pub struct HeapProfiler {
    config: HeapProfilingConfig,
    threshold_auto_dump_heap_profile: usize,
    jemalloc_dump_mib: dump_mib,
    opt_prof: bool,
}

HeapProfiler automatically triggers heap profiling when memory usage is higher than the threshold.

To use it, both jemalloc’s opt.prof and RisingWave’s config heap_profiling.enable_auto must be set to true.

Fields

config: HeapProfilingConfig

threshold_auto_dump_heap_profile: usize

jemalloc_dump_mib: dump_mib

opt_prof: bool

If jemalloc profiling is enabled

Implementations

impl HeapProfiler

pub fn new(total_memory: usize, config: HeapProfilingConfig) -> Self

Arguments

total_memory must be the total available memory for the process. It will be compared with the process resident memory.

fn auto_dump_heap_prof(&self)

pub fn start(self)

Start the daemon task of auto heap profiling.
