What is Processor Time Analysis Tool for Linux?
When processor resource is getting exhausted, it is crucial to find threads that consume most of processor resources. Processor Time Analysis Tool for Linux® analyzes Linux performance log and IBM Java ™ thread dumps to help you identify Java threads that consume the most processor resources.
How does it work?
The tool parses the Linux performance log and finds Java threads and processes that consume large amount of processor resources. It then creates charts of processor usage for Java processes and threads, parses IBM Java thread dumps and correlates Linux performance data and identifies processor usage, thread name, Java stack trace and native stack trace for each Java thread.
