Struct DemoSource 

pub struct DemoSource { /* private fields */ }

A DataSource with made-up readings that change over time.

Implementations

impl DemoSource

pub fn new(host: DemoHost) -> Self

A source playing host.

Trait Implementations

impl Clone for DemoSource

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl DataSource for DemoSource

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 watch_processes(&mut self, pids: Vec<u32>)

Processes to always include in snapshots, whatever the process limit, and to list in Snapshot::watched_pids, so that the client can tell when they exit. Replaces the previous list.

fn set_public_ip(&mut self, lookup: Option<PublicIpLookup>)

Looks up the host’s public address as lookup says (None: not at all, the default) and reports it in Snapshot::public_ip. Remote sources ask the agent, so each host reports its own.

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.

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

Limits snapshots to the top limit processes by CPU (None: all). Remote sources use this to save bandwidth for hosts in an overview.

fn watch_process_names(&mut self, _names: Vec<String>)

Like DataSource::watch_processes for every process matching one of names (see crate::view::process_matches) while it runs, and in the snapshot after it exited, so that the client sees it go. Replaces the previous list.

impl Debug for DemoSource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
