Start with user journeys
Identify the actions users or dependent systems need to complete so telemetry can explain whether those paths are working.
Reliable operation starts with knowing the important user journeys, dependencies, failure modes and ownership. Observability should reduce diagnostic uncertainty without collecting unnecessary sensitive information or promising an unsupported uptime target.
Identify the actions users or dependent systems need to complete so telemetry can explain whether those paths are working.
Know which databases, APIs, queues, identity providers, AI providers and infrastructure components each critical path depends on.
Logs, metrics, traces and health checks answer different questions. Collect the smallest useful set that makes failures diagnosable.
An alert is useful only when someone knows what it means, when action is required and what first diagnostic step to take.
Do not copy secrets, unnecessary personal data, full prompts or confidential payloads into logs merely because they are convenient for debugging.
Decide what can continue, queue, retry or fail clearly when a dependency is slow or unavailable.
Backups, rollback and failover assumptions should be exercised in ways appropriate to the system instead of existing only in documentation.
Use failures and support cases to improve instrumentation, runbooks, tests and architecture rather than treating recovery as the end of the work.
Describe the critical user journeys, dependencies, current telemetry, support pain points and recovery expectations so the right operational signals can be prioritized.
