Sentry is an application monitoring and error tracking solution designed to give developers insight into how their applications are performing in production environments.


  • Environments isolate different deployments of the same application.
  • SDKs intercept errors and send them into Sentry.
  • Events represent individual errors or transactions sent to Sentry.
  • Errors are representations of failure conditions, e.g. exceptions.
  • Issues are groupings of similar events, grouped by fingerprint.
  • Alert rules set conditions and a series of actions taken for events or issues.
