Tool Observability and Incident Response

Log Field Checklist Builder

Generate structured logging schemas by incident type. Configure required fields for HTTP, WebSocket, Worker, Database, and Exchange API incidents.

5incident types

Good structured logging is the foundation of incident response. When something breaks, you need to know what happened, when, and why. This builder generates JSON schema for structured logs based on the type of incident you are diagnosing.

http.methodstringrequired

HTTP method (GET, POST, PUT, DELETE)

http.urlstringrequired

Full request URL

http.status_codeintrequired

HTTP response status code

http.response_time_msintrequired

Response time in milliseconds

error.typestringrequired

Error classification (timeout, 429, 5xx, etc.)

error.messagestring

Error message from the response

retry.attemptint

Current retry attempt number

idempotency.keystring

Idempotency key used for the request

Frequently asked questions

Why is structured logging important?
Structured logging makes logs machine-readable and searchable. During incidents, you can query by field (error.type, http.status_code) instead of grepping text. This speeds up root cause analysis significantly.
What fields should I always include?
Always include: request ID, timestamp, error type, duration, and status code. For trading bots, also include exchange name, endpoint, and error code. The builder marks required fields for each incident type.
How do I use the generated schema?
The builder generates JSON Schema that you can use to validate your logs, generate typed classes, or document your logging standard. Import it into your logging library or use it as a reference for your team.

What engineers say

“The retry policy generator alone saved us from a production incident. We had exponential backoff configured wrong for months — the timeline visualization made it obvious instantly.”
