Struct OnDemandPIDResolver 

Source 
pub struct OnDemandPIDResolver { /* private fields */ }
Expand description

A resolver for mapping process IDs to their container IDs based on querying the underlying host.

§Platform support

On Linux platforms, PIDs are resolved by querying procfs to find the cgroup of the process, if one exists, the cgroup hierarchy is queried to discover the container ID that owns the process, if possible.

On all other platforms, OnDemandPIDResolver is a no-op and doesn’t perform any resolution.

Implementations§

Source§

impl OnDemandPIDResolver

Source

pub fn from_configuration( config: &GenericConfiguration, feature_detector: FeatureDetector, interner: GenericMapInterner, ) -> Result<Self, GenericError>

Creates a new OnDemandPIDResolver from the given configuration.

§Errors

If a cgroups hierarchy can’t be found, or the internal cache can’t be created, an error is returned.

Source

pub fn resolve(&self, process_id: u32) -> Option<EntityId>

Resolves a process ID to the container ID of the container is part of.

If the process ID isn’t part of a container, or can’t be found, None is returned.
