Struct LocalSource 

pub struct LocalSource { /* private fields */ }

Collects snapshots of the machine rigtop runs on.

Implementations

impl LocalSource

pub fn new() -> Self

Creates a source with the default configuration. See LocalSource::with_config.

pub fn with_config(config: &Config) -> Self

Creates a source and takes a warm-up sample, so that the first DataSource::poll (after at least MIN_POLL_INTERVAL) already has rates.

Only collection-related settings (the SMART directory) are used here; display settings such as sensor labels are applied by front-ends.

pub fn gpu_unavailable_reason(&self) -> Option<&str>

Why NVIDIA GPUs are unavailable, if NVML failed to initialize.

Trait Implementations

impl DataSource for LocalSource

fn set_process_limit(&mut self, limit: Option<usize>)

With a limit, only the top processes are shown (overview), which do not include per-process GPU utilization: skip that NVML query.

fn poll(&mut self) -> Result<Snapshot, SourceError>

Takes a new measurement.

fn signal_process( &mut self, pid: u32, signal: ProcessSignal, ) -> Result<(), SourceError>

Sends signal to process pid on the monitored host, with the privileges of the user the source runs as.

fn set_interval(&mut self, _interval: Duration)

Tells the source how often it will be polled. Remote sources forward this to the agent, which samples on its own schedule; local sources need nothing.

impl Default for LocalSource

fn default() -> Self

Returns the “default value” for a type.
