Struct tikv_jemalloc_ctl::profiling::lg_prof_interval

pub struct lg_prof_interval;

Average interval (log base 2) between memory profile dumps, as measured in bytes of allocation activity.

The actual interval between dumps may be sporadic because decentralized allocation counters are used to avoid synchronization bottlenecks.

Profiles are dumped to files named according to the pattern <prefix>.<pid>.<seq>.i<iseq>.heap, where <prefix> is controlled by the opt.prof_prefix and prof.prefix options. By default, interval-triggered profile dumping is disabled (encoded as -1).

Examples

use tikv_jemalloc_ctl::profiling;
let lg_prof_interval = profiling::lg_prof_interval::read().unwrap();
println!("average interval between memory profile dumps: {}", lg_prof_interval);

Implementations

impl lg_prof_interval

pub fn mib() -> Result<lg_prof_interval_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_interval

pub fn read() -> Result<ssize_t>

Reads value using string API.
