May 22, 2023: A company like Lumigo uses a set of tests to deploy code changes fast and relies on integration tests to ensure new changes work and don't break existing functionality. However, these tests can sometimes fail due to issues such as test code being too fragile or caching problems. To address this, the company recently switched from traditional logging methods to OpenTelemetry traces graphs, allowing them to better understand system behavior and identify issues that may be difficult to uncover through logging alone. By using OpenTelemetry, they can create meaningful graphs and timelines of events, including tracing test execution, external calls, logs, and more.
