Struct cgroups::cpuacct::CpuAcctController

source ·

pub struct CpuAcctController { /* private fields */ }

Expand description

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

In essence, this control group provides accounting (hence the name cpuacct) for CPU usage of the tasks in the control group.

Implementations

source

impl CpuAcctController

source

pub fn new(oroot: PathBuf) -> Self

Contructs a new CpuAcctController with oroot serving as the root of the control group.

source

pub fn cpuacct(&self) -> CpuAcct

Gathers the statistics that are available in the control group into a CpuAcct structure.

source

pub fn reset(&self) -> Result<()>

Reset the statistics the kernel has gathered about the control group.
