Abstract [en]

In recent years applications and internet services have begun to transition from monolithic systems to cloud- and distributed systems in order to achieve fault tolerant systems with high availability and scalability. As systems starts to span over dozens of servers, networks and infrastructures the old traditional means of monitoring and troubleshooting issues are no longer as accurate as before.‘ Those sorts of heterogeneous environments makes end-to-end metrics not credible when investigating requests and network communication over the cloud. Since there are no out-of-the box solutions to combine logs and metrics from multiple of diff‚erent services and timelines to one single causally correct entity.

Distributed tracing emerged as a solution to that issue by ignoring the system as a whole and instead treating it as a nestled collection of services that could be causally combined in order to understand the whole course of events. Th‘e goal of this is to solve where the problem occurred and why it occurred. Distributed tracing makes it possible by tracing network requests throughout it’s whole journey and collecting information of every service it passes through. ‘The end result is a directed acyclic graph comprised of logs and information of every a‚ffected service that can easily be used to monitor distributed systems.
