mtr

About

mtr is a network diagnostic tool that combines ping and traceroute into one program. Nixpkgs contains two flavors of it: the standalone application and a prometheus-ready exporter:

{
  programs.mtr.enable = true;
  services.mtr-exporter.enable = true;
}

Issues

mtr needs to be called with sudo

To avoid the need to escalate privileges when calling mtr create a setcap wrapper by setting

programs.mtr.enable = true;
