+# nfacct.plugin
+
+`nfacct.plugin` collects Netfilter statistics.
+
+## Prerequisites
+
+1.  install `libmnl-dev` and `libnetfilter-acct-dev` using the package manager of your system.
+
+2.  re-install Netdata from source. The installer will detect that the required libraries are now available and will also build `netdata.plugin`.
+
+Keep in mind that NFACCT requires root access, so the plugin is setuid to root.
+
+## Charts
