Implementing Robust Error Monitoring
In a distributed system, silent failures are the enemy. I integrated Sentry with custom context to pinpoint exactly which merchant is experiencing an issue.
- Contextual Tagging: Every error in Sentry is tagged with
shop_urlandplan_type, allowing us to prioritize issues for high-tier merchants. - Slack Integration: Critical 5xx errors trigger a Slack alert, reducing our Mean Time to Resolution (MTTR) by 50%.
- Log Aggregation: I use structured JSON logs in CloudWatch to trace a request from the initial webhook to the final DB update.
