we troubleshooted a CPU spike problem that surfaced in a major trading application in North America. All of a sudden, this application’s CPU started to spike up to 100%
Identifying the critical code path is essential for performance optimization and creating accurate test suites. Less than 5% of code often accounts for over 90% of execution time, making its optimization key. Thread dumps help in pinpointing these paths by grouping stack traces, enabling targeted testing and improved application performance.
fastthread.io is a tool designed to simplify the analysis of thread dumps, which are often analyzed manually in a labor-intensive way. It works with any language that operates on the JVM, enabling proactive troubleshooting of complex production issues. A video is available to demonstrate its ease of use.
The presentation titled "Don't Dump Thread Dumps" was delivered at the Great Indian Developer Summit (GIDS) in Bangalore. It aims to provide insights and best practices regarding the effective handling of thread dumps for developers. The content is available for review through the linked slideshare.
Fastthread.io offers a RESTful API for efficient thread dump analysis, eliminating manual tasks associated with DevOps teams. Users can automate root cause analysis, monitor performance, and integrate tests into continuous integration processes. The API allows for easy invocation with CURL commands, supports various compression formats, and provides valuable insights in JSON format.
