Monitor and Alert on Thresholds | Dataford Interview Questions

Write a script to monitor and alert on specific system resource thresholds.

Process chronologically ordered resource samples and generate one alert when a metric reaches or exceeds its threshold after being below it. A metric must fall below its threshold before another alert can be generated. Implement generate_alerts(samples, thresholds), returning alert dictionaries with timestamp, metric, and value.

Constraints

1 <= samples.length <= 10000
1 <= thresholds.length <= 1000
Each sample contains timestamp, metric, and numeric value fields
Samples are ordered by nondecreasing timestamp
A metric name is a non-empty string
A threshold exists only for metrics that should be monitored
A value equal to the threshold counts as a breach

Function Signature

def generate_alerts(samples, thresholds):
