Percona Toolkit is mature, proven in the real world, and well tested, but all database tools can pose a risk to the system and the database server. Before using this tool, please:

  • Read the tool's documentation
  • Review the tool's known "BUGS"
  • Test the tool on a non-production server
  • Backup your production server and verify the backups

pt-eustack-resolver is the tool that gets stack traces for a selected program with "eu-stack" and resolves symbols. This is companion tool for pt-pmp, called when option "--dumper=pteu" is specified.

"eu-stack" is a tool from elfutils https://sourceware.org/elfutils package that prints a stack for each thread in a process or core file. "eu-stack" is faster than gdb and have smaller overhead on the diagnosed process.

Stack for each thread, formatted similarly to "gdb thread apply all bt" output.

This tool accepts additional command-line arguments. Refer to the "SYNOPSIS" and usage information for details.

Show help and exit.
Show version and exit.

Using <PTDEBUG> might expose passwords. When debug is enabled, all command line parameters are shown in the output.

You need "eu-stack" from the elfutils https://sourceware.org/elfutils package.
