The JAX online conference gathers Java and software architecture enthusiasts globally. This year, an architect presented “Let's crash the applications!”, addressing issues like memory leaks, deadlocks, and CPU spikes through sample code. Understanding these triggers can simplify diagnosing and resolving related problems. Presentation slides are provided for reference.
The World’s Largest 6th Annual All Day DevOps conference took place on October 28, 2021, featuring architect Ram Lakshmanan, who presented a webinar on the "7 habits of highly effective Performance Troubleshooters." The presentation covered forecasting problems, addressing incidents in real-time, root cause identification, and prevention strategies.
On October 11, 2021, GCeasy experienced an outage due to HTTP 504 errors caused by inefficiencies in a new SQL query from a recent deployment. AWS CloudWatch monitored CPU and database connection spikes, while yCrash identified the problematic code. Commenting out the SQL query restored application performance.
The 'java.lang.System.getProperty()' API allows Java developers to read system properties but can degrade application performance when used in critical code paths due to synchronization issues. A real-world example shows 189 threads getting blocked, impacting response time. Solutions include upgrading to JDK 11 or caching property values for improved performance.
Naveen Kumar Namachivayam from QAInsights invites Ram Lakshmanan, the architect of yCrash, to speak at the Performance Engineers Clubhouse. Their discussion covers fundamental aspects of garbage collection, the significance of memory management, and introduces GC throughput, among other related topics, in an informative video.
fastThread Enterprise Edition significantly outperforms the Public and Premium editions with enhanced features, including problem detection, unlimited uploads, improved security, and automated data capturing. It enables extensive data analysis, tools integration, and collaboration for multiple users. Key features like dashboards, micro-metrics monitoring, and report comparison are exclusive to the Enterprise Edition.
The JAX Online Conference gathers Java and software architecture enthusiasts for knowledge sharing. This year features a webinar by an architect on “Major Outages in Major Enterprises,” focusing on analyzing thread dumps and other data to troubleshoot significant issues like CPU spikes and application unresponsiveness.
JAX - Online conference brings together Java and software architecture enthusiasts to share knowledge globally. This year featured a webinar on "JVM Internals in 1 slide," where attendees learned JVM fundamentals and how to troubleshoot, tune, and optimize JVM performance effectively. A presentation deck accompanies the session.
The post highlights the complexity of managing over 600 JVM arguments related to garbage collection and memory. It emphasizes seven key arguments across four videos that enhance application performance for Java, Scala, and Jython. Topics include heap size, thread stack size, garbage collection settings, and error handling.
