This September, we successfully hosted another engaging session in our performance engineering series: “Advanced Heap Dump Analysis Techniques.”
The webinar brought together developers, performance engineers, and JVM enthusiasts from across the globe to explore one of the most powerful yet often intimidating tools for diagnosing memory problems — heap dumps.
The session sparked insightful discussions, practical demonstrations, and real-world examples that made the subject approachable and actionable. Our expert speaker unpacked advanced analysis strategies, from querying with OQL to automating investigations with APIs, giving attendees confidence to handle even the largest and most complex dumps.
What the Webinar Covered
Heap dumps can feel overwhelming due to their size and complexity. But with structured techniques, they become a goldmine of diagnostic information.
In this webinar, we explored:
- How to query heap dumps with OQL (Object Query Language) for precise insights
- Automating investigations using Heap Dump Analysis APIs to save time and effort
- Strategies for handling remote heap dumps securely and efficiently
- Methods to trace incoming and outgoing references to identify leaks and retaining objects
- How to achieve a 360° JVM health view by correlating heap dumps with GC logs, thread dumps, NMT, kernel logs, and application logs
These techniques provided attendees with a systematic approach to uncover the root causes of memory leaks, high memory consumption, and OutOfMemoryErrors.
Why Advanced Heap Dump Analysis Matters
When applications run into memory issues, heap dumps often hold the answers. However, without the right tools and techniques, engineers can spend countless hours digging through noise.
By mastering advanced heap dump analysis, teams can:
- Reduce the time to identify memory leaks and inefficiencies
- Uncover hidden references that bloat the heap
- Automate recurring investigations to improve consistency
- Correlate multiple JVM artifacts for faster root cause analysis
Ultimately, this knowledge leads to healthier, more resilient Java applications and fewer production surprises.
Key Takeaways: Advanced Heap Dump Analysis Techniques
- OQL enables powerful, SQL-like queries for targeted memory investigations
- APIs allow repeatable, automated analysis workflows
- Remote dump handling is not only possible but efficient with the right setup
- Tracing references is essential for pinpointing leaks and retainers
- Cross-referencing heap dumps with other JVM artifacts accelerates troubleshooting
