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 ## DESCRIPTION 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 \ 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. ## OUTPUT Stack for each thread, formatted similarly to `"gdb thread apply all bt"` output. ## OPTIONS This tool accepts additional command-line arguments.
