👋 Hello Grafana & Friends Singapore! This month, we are excited to partner with the MongoDB for a collaborative evening of tech! As observability and data landscapes become increasingly complex, the integration between the LGTM stack and MongoDB is more critical than ever. This month, we are bringing together engineers from both ecosystems to share implementation strategies, architectural best practices, and real-world monitoring patterns. As always, come ready to learn, connect, and exchange ideas with the community. Light bites and networking included! **Topic 1: Real-Time Observability with MongoDB and Grafana: From Logs to Dashboard** **Speaker: Piti Champeethong**, Senior Consulting Engineer, MongoDB **Session Abstract:** Learn how to integrate MongoDB Atlas with Azure Grafana to build real-time dashboards for both database performance and application data. This session covers Prometheus-based monitoring, direct querying, and Azure-native pipelines for modern observability. **Topic 2: Agentic Observability: From OTel Signals to Production Remediation with MongoDB MCP** **Speaker: Hendri Tjiptowibowo**, Senior Partner Solutions Engineer, Grafana Labs **Session Abstract:** Learn how Grafana Assistant (available on OSS) combines OpenTelemetry signals with MongoDB MCP to move from observability to action. This session demonstrates AI-driven investigation of production issues, including trace analysis, query plan inspection, index recommendations, and automated remediation workflows. **📅 Date:** Thursday, June 11th, 2026 **🕡 Time:** 6:00pm - 9:00pm **📍 Location:** Smartworks Great Eastern Centre, 1 Pickering Street, Singapore 048659 - Level 8 ⚠️ **Reminder:** Please bring your valid physical photo ID (NRIC or Passport) to access the building. **Agenda** * **6:00 PM:** Registration, Light Bites & Networking * **6:55 PM:** Welcome & Opening * **7:00 PM:** Piti Champeethong, Senior Consulting Engineer at MongoDB – Real-Time Observability with MongoDB and Grafana: From Logs to Dashboard * **7:30 PM:** Hendri Tjiptowibowo, Senior Partner Solutions Engineer at Grafana Labs - Agentic Observability: From OTel Signals to Production Remediation with MongoDB MCP * **8:00PM:** Networking & Close **In Partnership with MongoDB:** This event is a collaborative session between **Grafana & Friends Singapore** and the **Singapore MongoDB User Group**.

**About the Speaker** **Simon Ritter** With over a decade of experience as Deputy CTO at Azul Systems, our speaker has helped shape the adoption of Java and JVM technologies across the global developer community. A recognized expert in Java and open source, he is passionate about advancing developer productivity, application performance, and innovation throughout the software ecosystem. **Agenda** **Keeping Your Java Hot by Solving the JVM Startup and Warmup Problem** Java bytecodes and class files deliver on the original vision of “write once, run anywhere”. Using a Just-in-Time (JIT) compiler allows JVM-based applications to compile only the code that’s used frequently and optimise it precisely for how it's used. Using techniques like speculative optimisation can often deliver better performance than static, Ahead-of-Time (AOT) compiled code. However, this flexibility and performance come at a cost. Each time the JVM starts an application, it must perform the same analysis to identify hot spots in the code and compile them. This is referred to as the application warmup time. In this session, we’ll look at several approaches to alleviating or even eliminating this problem. Specifically: · Static compilation of Java code ahead-of-time (AOT). Specifically, the Graal native image approach · Generating a JIT compiler profile of a running, warmed-up application that can be reused when the same application is restarted, eliminating the need for much of the JIT compilation. This will include details of the work of the OpenJDK Project Leyden. · Decoupling the JIT compiler from the JVM for a Cloud environment. Providing a centralised JIT-as-a-Service allows caching of compiled code and offloading the compilation work when new code must be compiled. · Creating a checkpoint of a running application. This includes all application state (heap, stack, etc.) in addition to the JIT-compiled code. Project CRaC will be used as an example. At the end of the session, you’ll be all set to keep your Java hot! **Modern Java Puzzlers** Since JDK 9, Java, as a language, has evolved faster than at any point in its 30-year history. For developers, this is great, as it means we get more new features that make our code more concise and, hopefully, easier to read and understand. All new language features also bring their quirks and possibly unseen consequences. In this fun interactive session, we’ll examine a range of recent language features and pose questions to the audience about how the code works and what it does. We’ll cover many of the new language features from recent releases, including switch expressions, sealed classes and pattern matching. We’ll even look at some curious ways special characters can be used in unexpected ways. The answers will most definitely not always be as you expect!

**For ages 17 and above.** The Quickstep was developed in the 1920s in suburban New York, and was greatly influenced by the Charleston fever of 1925. Seen as a light and fast-paced dance with smooth glides and chasses, the Quickstep is a dance with basic steps that are easy to learn for beginners, and provides an impressive expression of rhythm for advanced dancers. The Quickstep is certainly a fun dance for those who want to learn Ballroom dancing and also keep in shape. ### **Address** 795, North Bridge Rd, #02-01 797, 198763 ### **Schedule** Fridays 9PM - 10PM ### **Booking Information** * Please contact **98225900** to find out how to book this class. * The instructor will reach out to you once you've booked the class.
