“Oops! It’s the Network!”

No developer, operator, or engineer wants to hear this, but here we are! When the network presents a challenge it requires them to comb through a variety of systems and tools to find the culprit. This is challenging when operating at scale in heterogeneous platforms and environments. Also, when developers test or build something locally or in a cloud environment, connectivity challenges can be a barrier to progress. Maybe a developer is trying to address latency with tracing capabilities but needs a quick lesson on how to use a tracing tool. Perhaps a platform team needs a quick refresher on networking tools to quickly identify problem areas.

In this tutorial, Nele and Marino demonstrate how to discern and troubleshoot application issues across a few scenarios. We’ll use and describe several tools that operate at different OSI layers, how they pinpoint issues, and how they enable developers and operators to be more self-service oriented with network issues.
