> A design pattern that ships structured logs from every instance to one aggregated store.

Record: `architecture:centralized-logging`

Severity: recommended
Scope: services, platform

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Centralized Authentication](https://banes-lab.com/records/architecture/centralized-authentication.md) and before [Decentralization](https://banes-lab.com/records/architecture/decentralization.md).

## Repair

- Refactored by: Add Log Forwarder, Standardize Fields
- Detected by: missing log shipping
- Violated by: logs only available per instance
- Measured by: log ingestion coverage
- Enforced by: observability policy

## Requires

- [Log Aggregation](https://banes-lab.com/records/lexicon/log-aggregation.md)

## Reinforces

- [Observability](https://banes-lab.com/records/architecture/observability.md)
- [Auditability](https://banes-lab.com/records/architecture/auditability.md)

## Enables

- [Cross-Service Analysis](https://banes-lab.com/records/lexicon/cross-service-analysis.md)

## Conflicts with

- [Local-Only Logs](https://banes-lab.com/records/lexicon/local-only-logs.md)

## In tension with
