Sampling ownership and polling lifecycle. Process resource collection, sampling ownership, and polling lifecycle.

## Structs

* [ResourceMetricsRuntime](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/struct-resourcemetricsruntime): Owns the optional resource metrics polling thread for a built-in plugin activation.

## Functions

* [collect_on_demand](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-collect-on-demand)
* [ensure_process_owner](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-ensure-process-owner)
* [invalidated_snapshot](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-invalidated-snapshot)
* [latest_memory_view](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-latest-memory-view): Read an existing manager only. Inspection must not resolve settings, start a manager, collect, or retarget it. Fork checks precede every potentially inherited lock.
* [prepare_cli_owned_process_tree](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-prepare-cli-owned-process-tree)
* [runtime_inherited_across_fork](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-runtime-inherited-across-fork)
* [target_owned_process_tree](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/fn-target-owned-process-tree)

## Type Aliases

* [SnapshotSink](/nemo/relay/dev/reference/api/rust-library-reference/nemo-relay-resource-metrics/manager/type-snapshotsink): Receives each periodic resource snapshot.
