Module alerts 

Alert evaluation engine.

Evaluates DOL alert rules against live metric samples. Supports duration guards (e.g. “for 2m”) and actions: print, webhook (HTTP POST), and restart (container restart via bollard).

Example

let rule = parser::parse(r#"alert when cpu > 80% for 2m then print "High""#)?;
let mut evaluator = AlertEvaluator::new();
let events = evaluator.evaluate_samples(&rule, &samples, Instant::now())?;
