The feature

Currently Immich outputs logs in plain text (NestJS default style). This makes it harder to integrate with observability stacks such as Grafana Loki + Promtail, ELK, or other log aggregators that rely on structured data.

It would be very helpful to have a configuration option (for example an environment variable like IMMICH_LOG_FORMAT=json) so that the application can emit structured JSON logs.

At the moment the only alternative is to parse the plain text logs with regex in Promtail, which is brittle and error-prone. Metrics and tracing are useful, but JSON logs would provide a much cleaner and standard solution.

Structured JSON logging is a common practice in containerized environments (Kubernetes, Docker) and makes observability much simpler. Having native JSON logging would improve integration with:

• Grafana Loki / Promtail
• ELK stack
• Any cloud logging service that expects JSON

Thank you for considering this feature!
