Struct cgroups_rs::pid::PidController

source · [−]

pub struct PidController { /* private fields */ }

Expand description

A controller that allows controlling the pids subsystem of a Cgroup.

Implementations

source

impl PidController

source

pub fn new(root: PathBuf, v2: bool) -> Self

Constructors a new PidController instance, with root serving as the controller’s root directory.

source

pub fn get_pid_events(&self) -> Result<u64>

The number of times fork failed because the limit was hit.

source

pub fn get_pid_current(&self) -> Result<u64>

The number of processes currently.

source

pub fn get_pid_max(&self) -> Result<MaxValue>

The maximum number of processes that can exist at one time in the control group.

source

pub fn set_pid_max(&self, max_pid: MaxValue) -> Result<()>

Set the maximum number of processes that can exist in this control group.

Note that if get_pid_current() returns a higher number than what you are about to set (max_pid), then no processess will be killed. Additonally, attaching extra processes to a control group disregards the limit.
