Note that this plugin does _not_ collect firewalld information, which is handled by a separate plugin. Collections from this plugin are largely gated byt the presence of relevant kernel modules - for example, the plugin will not collect the nf_tables ruleset if both the `nf_tables` and `nfnetlink` kernel modules are not currently loaded (unless using the --allow-system-changes option). zfirewall tablesZfirewall_tables)�network�system)� /etc/nftables)Z ip_tablesZ ip6_tables� nf_tables� nfnetlinkZebtablesc C s2 d| }d| d }| j |t| |dgd�d� dS )z� Collecting iptables rules for a table loads either kernel module of the table name (for kernel <= 3), or nf_tables (for kernel >= 4).
