About This Tool
Conceptually, it builds a thread interaction graph, applies deadlock-detection logic, and ranks threads by wait time. It can handle multiple dumps to observe cross-dump patterns.
Who benefits: SREs and developers debugging backend services, platform teams profiling latency sources, and incident responders needing rapid root cause. Unique value: automated deadlock detection, clear bottleneck signals, and easy export for automation. Core features include parsing, normalization, deadlock analysis, contention hotspots, per-stack aggregation, and export options (JSON/CSV). Typical use cases include post-mortem investigations, proactive health checks, and performance tuning of Java services.
How to Use
- Provide inputs: paste the thread dump text into the input field and set optional settings as needed.
- Choose method: select output format and whether to include system properties or filter by package.
- Run analysis: submit to process the dump and wait for results.
- Review outputs: read the summary, check deadlock details, and inspect hotspot lists.
- Export data: download JSON/CSV or copy the report for automation.
