The following error occurred: [telegraf] Error running agent: Error parsing /etc/telegraf/telegraf.conf, line 3467: field corresponding to sadc_path 'is not defined in * system.SystemStats'
The # indicates a comment in TOML; right now the [[inputs.sysstat]] section of your config file is still commented out, which deactivates the plugin. In order to activate it, uncomment the section.
I suspect you will also have to remove the spaces from the sadc_path.
