# Monitoring Dashboard Configuration

## Objective

Define baseline dashboards and alert thresholds for reliability and freshness checks.

## Dashboard Panels

1. API p95 latency for `/api/news` and `/api/news/latest`
2. API error rate (`5xx`) by route
3. Scheduler success/failure count per hour
4. Feed freshness lag (minutes since latest published item)

## Alert Thresholds

- API latency alert: p95 > 750 ms for 10 minutes
- API error-rate alert: `5xx` > 3% for 5 minutes
- Scheduler alert: 2 consecutive failed fetch cycles
- Freshness alert: latest item older than 120 minutes

## Test Trigger Plan

- Latency trigger: run stress test against `/api/news` with 50 concurrent requests in staging.
- Error-rate trigger: simulate upstream timeout and confirm 5xx alert path.
- Scheduler trigger: disable upstream API key in staging and verify consecutive failure alert.
- Freshness trigger: pause scheduler for >120 minutes in staging and confirm lag alert.
