Production GraphQL systems often need observability and lifecycle behavior around requests.

Apollo Server provides a plugin architecture that can be used for concerns such as:

• request timing
• logging
• tracing
• metrics
• usage reporting
• startup and shutdown behavior

Conceptually, a plugin can observe a request lifecycle:

Request begins
    ↓
Operation parsed
    ↓
Validation
    ↓
Execution
    ↓
Response created
    ↓
Request completed

This is useful when you need consistent instrumentation without adding logging code to every resolver.

For example, a request logger can record:

requestId=abc123
operation=GetDashboard
duration=84ms
status=success

Resolver-level logs can then add details for individual operations.

Avoid logging entire GraphQL variables blindly. Variables can contain passwords, access tokens, personal data, or other sensitive values.

A good observability strategy records enough information to diagnose production behavior while deliberately excluding secrets and sensitive payloads.
