# Monitoring

> A mechanism that collects metrics about resources and service levels over time and compares them with thresholds.

Record: `architecture:monitoring`
Kind: mechanism
Layer: [Observability](https://banes-lab.com/records/layer/observability.md)
Severity: mandatory
Scope: service, infrastructure
Canonical: https://banes-lab.com/ontology#architecture-monitoring

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Logging](https://banes-lab.com/records/architecture/logging.md) and before [Alerting](https://banes-lab.com/records/architecture/alerting.md).

## Repair

- Refactored by: Add Metrics, Define SLIs
- Detected by: missing dashboards/SLI metrics
- Violated by: no metrics for critical resources/SLIs
- Measured by: metric coverage, detection latency
- Enforced by: production readiness checklist
