All the unit tests & the largest QA team still can’t stop bugs from slithering into production. With a distributed microservice architecture debugging becomes much harder. Especially across language & machine boundaries. APMs & logs provide the first steps. But in these crucial moments we need something more. Production bugs are the WORST bugs. They got through unit tests, integration, QA & staging… We cross our fingers, put on the Sherlock Holmes hat & hope the bug made it into the log… If not our only remedy is more logging. That bogs performance for everyone & makes logs damn near unreadable. We have no choice other than crossing our fingers & going through CI/CD again... again... again... With continuous observability we can follow a specific process through several different microservices and “step into” as if we were using a local debugger without interrupting the server flow. In this session I will demonstrate such an approach and how everything integrates into elastic nicely.
