Visualising and Tracing Requests Through a Cluster - Integrating OpenTracing into OpenStack Swift

Explore the integration of OpenTracing into OpenStack Swift in this 46-minute conference talk from linux.conf.au. Dive into the world of request visualization and tracing within clusters, learning how this approach can benefit SREs and Ops teams. Discover how tagging requests and integrating tracing into the software itself can provide valuable insights into inter-node requests and node-specific activities. Gain understanding of how this method allows for better cluster configuration tuning, topology optimization, and identification of areas requiring developer focus. Follow along as the speaker demonstrates the evolution from middleware benchmarking to comprehensive request tracing, showcasing the ability to visualize request time allocation, understand different request patterns within the cluster, and utilize this information for performance optimization. The talk covers topics such as Swift overview, OpenTracing integration, transaction IDs, object operations, and concludes with benchmarks and a Q&A session.
