Its only been a year since ChatGPT was introduced. Since then we see LLMs (Large Language Models) and Generative AIs being integrated into every days life software applications. Developers have the hard choice to pick the right model for their use case to produce the quality of output their end users demand.Tune in to this session where we have Nir Gazit, CEO and Co-founder of Traceloop, educating us about how to observe and quantify the quality of LLMs. Besides performance and costs engineers need to look into quality attributes such as accuracy, readability or grammatical correctness.Nir introduces us to OpenLLMetry - a set of Open Source extensions built on top of OpenTelemetry providing automated observability into the usage of LLMs for developers to better understand how to optimize the usage of LLMs. His advice to every developer is to start measuring the quality of your LLMs on Day 1 and continuously evaluate as you change your model, the prompt and the way you interact with your LLM stack!If you have

After analyzing Distributed Traces over more than 15 years Brian and I thought that everyone in software engineering and operations must be satisfied with all that observability data we have available. But. Maybe Brian and I were wrong because we didn’t fully understand all the use cases - especially those for developers that must fix code in production or need to quickly understand what code from somebody else is really doing without having the luxury to add another log line and redeploy on the fly. To learn more about the observability requirements of developers we invited Liram Haimovitch, CTO at Rookout and now part of Dynatrace, who has spent the last 7 years solving the challenging problems that developers face day and night. Tune in and learn about what non-breaking breakpoints are, how it is possible to "debug in production" without impacting running code and how we can make developers lives easier even though we push so many things "to the left"

I was invited to speak at BankTechShow in Budapest, Hungary where the nations IT leaders in the banking sector presented and discussed the future of banking - both in the cloud as well as what it means for the physical bank branches. I got a chance to sit down with Adam Gajdi, IT Solutions CoE Lead at K&H, who walked me through the process of their recent new mobile banking app launch. Adam highlighted the importance of observability for both business owners as well as developers. Furthermore, Adam enlightened me with the fact that Hungarian banks are mandated to conduct chaos tests to proof that their systems are resilient in case of data center outages. I was obviously also curious about how AI, LLMs and other technologies are adopted in their sector. Tune in to learn more

Martin Spier was one of six engineers to take care of all of Netflix Operations about 10 years ago. Back then performance and observability tools weren't as sophisticated and didn't scale to the needs of Netflix as some do today. FlameScope was one of the Open Source projects that evolved out of that period, visualizing Flame Graphs on a time-scaled heatmap to identify specific performance patterns that caused issues in their complex systems back then.Tune in to this episode and hear more performance and observability stories from Martin, about his early days in Brazil, his time at Expedia and Netflix and about his current role as VP of Engineering at PicPay - one of the hottest fin techs in Brazil.More links we discussed:Performance Summit talk about FlameCommander: https://www.youtube.com/watch?v=L58GrWcrD00CMG Impact talk on Real User Monitoring at Netflix: https://www.cmg.org/2019/04/impact-2019-real-user-performance-monitoring-at-netflix-scale/Learn more about Vector: https://netflixtechblog.com/extendin

Africa is not only the second largest continent in the world - its also top when it comes to adoption of cloud native technologies. I was fortunate to spend a week in South Africa and had the chance to spend a lot of time with Kelvin Klein, Dynatrace Product Manager at Mediro ICT.

Do you measure build times? On your shared CI as well as local builds on the developers workstations? Do you measure how much time devs spend in debugging code or trying to understand why tests or builds are all of a sudden failing? Are you treating your pre-production with the same respect as your production environments?Tune in and hear from Trisha Gee, Developer Champion at Gradle, who has helped development teams to reduce wait times, become more productive with their tools (gotta love that IDE of yours) and also understand the impact of their choices to other teams (when log lines wake up people at night). Trisha explains in detail what there is to know about DPE (Developer Productivity Engineering), how it fits into Platform Engineering, why adding more hardware is not always the best solution and why Flaky Tests are a passionate topic for Trisha.Here the links to Trishas social media, her books and everything else we discussed during the podcastLinkedIn: https://www.linkedin.com/in/trishagee/Trishas We

Do you know why customers spend more money at a pub when ordering at a table vs ordering directly from at the bar tender? Do you want to know how to get SaaS vendors to send you their observability & telemetry data? Do you want to know the career path of how an Infrastructure Analyst turned Digitial Readiness Manager?Tune in to this PurePerformance episode where we sat down with Mark Forrester from Mitchell & Butlers answering all these questions and also drawing the parallels to Observability. Because observability has come a long way just as Mark: From traditional infrastructure (CPU, Memory, Network) to APM (Service Response Time & Failure Rates), to Real User Behaviour and now End-2-End Business Processes Analytics. Unlocking the potential of Digitial Business Observability lets Mark optimize the end-2-end customer journey to make sure their customers always feel like they are taken care of when trying to order online food delivery, a meal or a drink at a restaurant. As you learn, digital busi

As far as we know - besides Kubernetes there is only Prometheus that belongs to the prestigious group of open-source projects that have their own documentary. Now why is that? Prometheus has emerged as the go-to solution for capturing metrics in modern software stacks, earning its status as the de facto standard. With its widespread adoption and a constantly expanding ecosystem of companion tools, Prometheus has become a pivotal component in the software development landscape.Join us as we sit down with Björn Rabenstein, an accomplished engineer at Grafana, who has dedicated nearly a decade to actively contributing to the Prometheus project. Björn takes us on a journey through the project's early days, unravels the reasons behind its meteoric rise, and provides us with insightful technical details, including his personal affinity for Histograms.Here are the links we discussed during the podcast for you to follow up:Prometheus Documentary: https://www.youtube.com/watch?v=rT4fJNbfe14First Prometheus talk at SRE

APIs are powering and empowering software innovation as they enable new use cases on top of existing services. Observability into API usage to answer questions like: how APIs are called, what APIs do, where APIs fail, where APIs are slow, where APIs are misused … has to be on top of mind for architects that decide to build or use APIs.In this episode we welcome Sonja Chevre, Group Product Manager at Tyk, who recently gave a captivating talk at KubeCon about using OpenTelemetry to get insights into popular API frameworks such as GraphQL. We are discussing common challenges for SREs such as that APIs often hide the status of a call behind an HTTP 200 or that debugging individual calls is really hard as details of the call are not exposed by default to telemetry data. We also cover topics such as API-led growth, API as a product as well as open standards such as OpenTelemetry and OpenAPI. Here the list of discussed links during the show:KubeCon Talk: https://kccnceu2023.sched.com/event/1HyVc/what-could-go-wrong-
