Struct tikv_jemalloc_ctl::profiling::lg_prof_sample

pub struct lg_prof_sample;

Average interval (log base 2) between allocation samples, as measured in bytes of allocation activity. Increasing the sampling interval decreases profile fidelity, but also decreases the computational overhead.

The default sample interval is 512 KiB (2^19 B).

Examples

use tikv_jemalloc_ctl::profiling;
let lg_prof_sample = profiling::lg_prof_sample::read().unwrap();
println!("average interval between allocation samples: {}", lg_prof_sample);

Implementations

impl lg_prof_sample

pub fn mib() -> Result<lg_prof_sample_mib>

Returns Management Information Base (MIB)

This value can be used to access the key without doing string lookup.

pub fn name() -> &'static Name

Key crate::keys::Name.

impl lg_prof_sample

pub fn read() -> Result<size_t>

Reads value using string API.
