Struct OomCounters 

pub(super) struct OomCounters {
    oom: u64,
    pub(super) oom_kill: u64,
    pub(super) has_kill: bool,
}

The OOM related counters of a memory events file.

Fields

oom: u64

Times the memory limit of the cgroup was hit.

oom_kill: u64

Processes killed because of it. Kills are accounted to the victim’s leaf cgroup, so this drifts apart from oom by design and the two are compared separately.

has_kill: bool

Whether the file has the kill counter, which kernels since 4.13 do.

Implementations

impl OomCounters

fn increased_since(&self, baseline: &Self) -> bool

Whether a process got killed since baseline. The kernel counts an oom before the OOM killer runs, which may kill nothing, if reclaim freed enough memory meanwhile or a victim is exiting already, so only kernels without the kill counter fall back to it.
