Configuring debug symbols

These days many debugging tools can fetch debug symbols from debuginfod servers. The official project page lists the URLs you should use for each supported distribution. For example, in my Arch Linux, the DEBUGINFOD_URLS environment variable is set to https://debuginfod.archlinux.org by the /etc/profile.d/debuginfod.sh script (a part of the libelf package).

If you want this variable to be preserved when running commands with sudo, you can add a rule such as the following to a file in /etc/sudoers.d/ (e.g., /etc/sudoers.d/debuginfod):

Defaults env_keep += "DEBUGINFOD_URLS"

Installing monitoring tools

If you are looking for a tool that will allow you to monitor running processes in the system, you may consider installing one of the tools listed below

GUI tools

  • Mission Center is my favourite GUI app listing processes running in the system as well as providing insights into system CPU and memory usage, and services status. On Arch, install using: sudo pacman -Sy mission-center
  • Resources is a monitoring app which will become a default Gnome system montoring app, very similar to Mission Center
  • TuxManager is a Qt-based monitoring app, similar to Microsoft’s Task Manager.

TUI tools

  • btop
  • Glances is an interesting choice if you’re looking for a TUI or web application. You may run it with uv, for example: uv tool run --with fastapi --with uvicorn --with jinja2 glances -w --bind 127.0.0.1. Then open http://127.0.0.1:61208/ in the browser. The ‘h’ key will show you available shortcuts.
