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.
