== nvidia-smi ==

To enable the <code>nvidia-smi</code> plugin you have to make sure <code>nvidia-smi</code> can be called by <code>netdata</code>.

<pre>systemd.services.enable = true;
systemd.services.netdata.path = [pkgs.linuxPackages.nvidia_x11];
services.netdata.configDir.&quot;python.d.conf&quot; = pkgs.writeText &quot;python.d.conf&quot; ''
  nvidia_smi: yes
'';</pre>
== samba ==

To enable <code>samba</code> plugin a lot of things need to be done.

<blockquote>Still I could not make samba to work, because systemd services seem to be forbidden to run sudo. Please update if you are able to make it work.

<pre>systemd.services.enable = true;
services.netdata.configDir.&quot;python.d.conf&quot; = pkgs.writeText &quot;python.d.conf&quot; ''

# add samba and sudo to path of python plugin
systemd.services.netdata.path = [ pkgs.sudo pkgs.samba ];

# permit to run sudo smbstatus -P

  netdata ALL=(root) NOPASSWD: ${pkgs.samba}/bin/smbstatus
