Struct cgroups_rs::perf_event::PerfEventController

source · [−]

pub struct PerfEventController { /* private fields */ }

Expand description

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

In essence, when processes belong to the same perf_event controller, they can be monitored together using the perf performance monitoring and reporting tool.
