Struct CgroupsMetadataCollector 

pub struct CgroupsMetadataCollector { /* private fields */ }

A metadata collector that observes Linux “Control Groups” (cgroups).

This collector specifically tracks cgroup controllers attached to container workloads using simple regex-based matching against the controller path, and maintains a mapping of controller inodes to the container ID extracted from the controller path.

This is specifically used to support client-based Origin Detection in DogStatsD, where clients will either send their detected container ID or the inode of their cgroup controller. A canonical container ID must always be used for origin enrichment, so this mapping allows resolving controller inodes to their canonical container ID.

Implementations

impl CgroupsMetadataCollector

pub async fn new( cgroups_config: &CgroupsConfiguration, health: Health, interner: GenericMapInterner, ) -> Result<Self, GenericError>

Creates a new CgroupsMetadataCollector from the given cgroups configuration.

Errors

If a valid cgroups hierarchy can not be located at the configured path, an error will be returned.
