Define your reliability targets before you pick tools
Start with explicit targets for uptime, error budget, and acceptable latency for core user journeys. Map those targets to your most important product flows such as signup, billing, and dashboard load. When you agree on service-level goals first, you can measure the right things and stop chasing vague alerts that do not impact customers.
Why this matters: Observability without standards becomes endless noise. Targets give your team a concrete definition of “healthy” and a shared threshold for action.
