Capturing Exception Stacks

When a performance exception is detected, you need to capture and analyze the related stack information in a timely manner.

• Viewing based on GDB

  gdb -p <pid>
  # Access the GDB CLI and print the call stack of the process or main thread.
  bt
  # View the call stack of a thread.
  info threads
  thread<n>
  bt

• Viewing based on pstack

  pstack <pid>

• Viewing based on cat

  cat /proc/<pid>/stack
