Module ore::cgroup

Linux cgroup detection utilities.

Structs

CgroupEntry

An entry in /proc/self/cgroup

MemoryLimit

Represents a cgroup memory limit, with both ram and swap maximums if they exist. Fields should be None if a limit does not exist or when running on a platform without cgroup support (ie: non-Linux platforms).

Mountinfo

An entry in /proc/self/mountinfo

Functions

detect_memory_limit

Returns the cgroup (v1 or v2) memory limit if it exists.

parse_proc_self_cgroup

Parses /proc/self/cgroup into a Vec, if the file exists.

parse_proc_self_mountinfo

Parses /proc/self/mountinfo into vectors of Mountinfo objects, returning (v2_mounts, v1_mounts).

read_file_to_usize

read_v1_memory_limit

Finds the cgroup v1 and mountpoint combination containing the memory controller, and reads the memory limits within.

read_v2_memory_limit

Finds the mountpoint corresponding to the provided cgroup v2, and reads the memory limits within.
