Can any one help me in finding out what is the CPU usage per thread. This will be instantly recognized if the cpu% reported is >100% for a process or thred but can be misleading if you see 50 threads with 20% cpu utilization. Not the answer you're looking for? It has many more features than top, including showing individual threads and individual CPU usage etc. http://rdiyewar-tech.blogspot.com/2013/04/per-thread-cpu-usage-on-linux.html

The investigation itself has been applied to many thousands of performance problems. Htop Thread Name The threaddumps or javacores will then be correlated to the system thread information. To see the per cpu usage in header section, press 1. This spread implies that no one thread has a particular problem.

Note that the "Cpu(s)" line in the header of the output shows the percentage usage across all of the available CPUs, whereas the %CPU column above represents the percentage usage of Javacores will be named (by default) javacore.yyyymmdd.hhmmss..0001.txt and will reside in the home directory of the JAVA process. 0001 is a sequence number and will increment for each javacore for the Linux Show Threads Per Process It will usually result in minimizing the number of threads to be investigated.

In Linux, threads (also called Lightweight Processes (LWP)) created within a program will have the same "thread group ID" as the program's PID.
