Struct AlertLog 

pub struct AlertLog { /* private fields */ }

The alerts of every host as they appear and clear, so that what happened while nobody watched can be looked up later.

Implementations

impl AlertLog

pub fn persistent(path: PathBuf) -> Self

A log kept in path: the events of earlier runs are loaded, alerts they left raised count as still present (so a restart does not log them again), and new events are appended. A file that cannot be read or written leaves the log working in memory.

pub fn update(&mut self, host: &str, alerts: &[Alert], at_ms: u64)

Records how the alerts of host changed since its previous update.

pub fn events(&self) -> impl DoubleEndedIterator<Item = &AlertEvent>

All events, oldest first.

pub fn unread(&self) -> (usize, Option<Severity>)

Alerts raised since the log was last read, and the most severe one.

pub fn mark_read(&mut self)

Marks every event as read.
