Monitoring

Sentry

Sentry is a tool used for monitoring, prioritizing, and debugging errors. The dashboard provides real-time visibility into platform errors and it enables developers to quickly identify and resolve issues that impact application performance and user experience.

  • Error Monitoring: Errors on our platforms are reported to Sentry, with detailed information about each error, including the stack trace, request information, and metadata. One can know in which brand the error was caused, which application (e.g web, courses, pinboard) as well as information on the client side (operating system).

  • Prioritization: It automatically groups similar errors together, so errors that are occurring most frequently can be prioritized accordingly.

  • Debugging: Sentry provides detailed information about each error, making it easier to identify the root cause and fix the defect.

An example of how our app reports errors to Sentry:

rescue Restify::ClientError => e
  ::Sentry.capture_exception(e)

Frontend Error Tracking

Frontend JavaScript errors should be captured and reported to Sentry. In application code, prefer the shared handleError utility (app/assets/util/error.ts), which reports to Sentry and optionally shows a user-facing message. Unhandled exceptions and promise rejections are tracked automatically.
