Pattern: Exception tracking

Context

You have applied the Microservice architecture pattern. The application consists of multiple services and service instances that are running on multiple machines. Errors sometimes occur when handling requests. When an error occurs, a service instance throws an exception, which contains an error message and a stack trace.

Problem

How to understand the behavior of an application and troubleshoot problems?

Forces

  • Exceptions must be de-duplicated, recorded, investigated by developers and the underlying issue resolved
  • Any solution should have minimal runtime overhead

Solution

Report all exceptions to a centralized exception tracking service that aggregates and tracks exceptions and notifies developers.

Resulting Context

This pattern has the following benefits:

  • It is easier to view exceptions and track their resolution

This pattern has the following drawbacks:

  • The exception tracking service is additional infrastructure
  • Log aggregation - exceptions should be logged as well as reported to a tracking service
