Struct ExitWatch 

pub struct ExitWatch { /* private fields */ }

The processes of one host to announce when they exit. The front-end passes ExitWatch::pids to the source (crate::DataSource::watch_processes), which then keeps them in snapshots whatever the process limit.

Implementations

impl ExitWatch

pub fn contains(&self, pid: u32) -> bool

Whether pid is watched.

pub fn toggle(&mut self, process: &ProcessInfo, now_ms: u64) -> bool

Starts or stops watching process; true when it is now watched.

pub fn watch_as( &mut self, process: &ProcessInfo, label: Option<&str>, now_ms: u64, ) -> bool

Starts watching process unless it is watched already, naming it label when it exits. True when it was not watched before.

pub fn pids(&self) -> Vec<u32>

The watched pids, for the source.

pub fn state(&self, snapshot: &Snapshot, pid: u32) -> WatchState

What snapshot says about the watched process pid.

pub fn check(&mut self, snapshot: &Snapshot, now_ms: u64) -> Vec<Alert>

Stops watching the processes that exited by snapshot and returns an alert for each: “train.py (pid 1234) exited after 3h12m”.
